Application of Ultrasonic Spot Welding Technology in Lithium Ion Battery Industry

Application of Ultrasonic Spot Welding Technology in Lithium Ion Battery Industry

As a key part of the lithium battery manufacturing process, the ultrasonic welding process is applied to the lithium battery; aluminum foil/copper foil positive and negative current collectors, electrodes, and battery packaging are connected at multiple locations. Any defect in the welded joint will affect the consistency of the performance of the lithium battery. So it is necessary to understand the ultrasonic welding process. In the ultrasonic welding process, the sensor converts high-frequency electrical signals into ultrasonic vibration signals. The high-frequency vibration is transmitted to the surface of the welded metal through the welding joint, and the interface metal oxide film is broken under a certain pressure and strength. Ultrasonic vibration and friction, under the combined action of friction and ultrasound, further soften the flow and diffusion of plastic, gradually increase the connection area and finally realize the connection. The strength of the welded joint decreases as the pressure increases. The welding pressure changes the sliding resistance. A small welding pressure will cause the sliding resistance of the interface to be small, so that the energy generated by friction is not enough to form an effective connection at the interface, and the welding pressure will cause the tool head to be pressed too deeply. Therefore, the advancing welding pressure parameter plays a decisive role in welding quality. The welding time directly affects the energy input during the welding process, and has a direct effect on the welding effect. The welding time is too short and the input energy is insufficient. Due to insufficient friction, it is difficult to form an effective solder joint; if the welding time is too long, the temperature rises and mutual friction causes the workpiece material to soften. The oxide film at the interface of the welding zone is destroyed and plastic deformation, which can form more Good connection, when the welding time is further extended, the welding head is likely to form deeper marks on the surface of the workpiece, which will affect the welding effect. If the welding time is too long, it will easily cause the welding head and the workpiece to be welded. In the ultrasonic welding process, the vibration system formed by the workpiece and the workpiece directly affects the instantaneous speed of vibration at the interface of the workpiece, and ultimately affects the frictional heating and plastic deformation, thereby affecting the welding quality.
Lithium Battery Electrode Roller Press synopsis

Lithium Battery Electrode Roller Press synopsis

First, adjust the power switch of the electrode rolling machine,Then wipe the steel roller with a cloth dipped in alcohol. Confirm the following three points before starting up. 1. Check that the emergency stop switch remains connected before powering on 2. The surface of the steel roller is dry, clean, free of oil and particles. 3 Adjust the gap between the steel rollers. There are different rolling parameters in the battery mode. Don't move around here. Pay attention to the rolling stroke to avoid motor failure. Second, take a suitable electrode roller press, 1 Adjust the gap between steel rolls to the range of process requirements. 2. Keep the balance between the electrode and the micrometer. Place the material on the unwinding shaft and adjust it to a proper position. Place the electrode between the two rollers. The electrode is required to be parallel to the front and back, and cannot be mounted sideways in the air or tilted. Turn on the tension system and automatic correction system in front of the roller press, and pay attention to adjusting the tension not too tight or too loose. Third, during the electrode rolling process, the weight requirements are as follows: 1. Pay attention to the perpendicularity of the electrode and the micrometer. 2. Keep the hand movement speed the same as the electrode movement speed. After the material is rolled, the surface of the roller should be wiped. Use an anti-rust agent to wipe the surface of the roller to keep it clean. If there are no two roller presses, one roller press must be used to process the cathode and anode at the same time, and the roller must be cleaned. In addition, the electrode will have moisture after being rolled, so it should be placed in an oven for baking.
How Much Lithium Carbonate Is Needed In An Electric Car

How Much Lithium Carbonate Is Needed In An Electric Car

How Much Lithium Carbonate Is Needed In An Electric Car First of all, judging from a big assessment, someone once investigated lithium iron phosphate battery companies.According to them, about 1GWh of lithium iron phosphate battery requires 2000-2500 tons of cathode material, and one ton of lithium iron phosphate material requires about 0.25 tons of lithium carbonate( LiCoO2 ) From a micro point of view: a 60kWh lithium iron phosphate battery, a car needs 30kg lithium carbonate; From a macro point of view: if we calculate according to a 60kWh car, 100,000 cars 6GWh and 1 million 60GWh, the corresponding demand for lithium carbonate is 30,000 tons respectively.According to China's lithium carbonate output in 2020 is 166,000 tons, a year-on-year increase of 4.4%, of which battery-grade lithium carbonate production is 106,000 tons, and industrial-grade lithium carbonate production is 60,000 tons.That is to say, 100,000 tons of battery-grade lithium carbonate, all made of lithium iron phosphate batteries correspond to 200GWh. At that time, another argument was that 0.25 tons of lithium carbonate was used as a positive electrode lithium iron phosphate material of 10,000 tons, corresponding to 4-5GWh batteries, which was related to the difference in energy density.

Demand for aluminum foil for power batteries increases

As the current collector of lithium battery cathode materials aluminum foil has a low cost ratio in lithium batteries but is indispensable. Driven by the continued boom in the new energy automotive industry, the market demand for lithium battery aluminum foil ushered in an explosion The energy vehicle market continued its high growth trend in the fourth quarter of last year, which led to a significant year-on-year increase in power battery installed capacity, and a surge in demand for lithium battery aluminum foil market, which helped many aluminum foil companies to increase their orders and shipments. Unlike the aluminum foil used for the positive electrode current collector of lithium batteries and the copper foil used for the negative electrode, both the positive and negative electrode current collectors of sodium ion batteries can use aluminum foil, which will create new market growth space for aluminum foil. Corresponding to the huge market demand. At present, only a few companies in China, such as North China Aluminum, Nanshan Aluminum, Dingsheng New Materials, Dongyang Branch, Mingtai Aluminum, and Wanshun New Materials, have the ability to mass produce and supply aluminum foil for lithium batteries. And the overall production capacity is small.
Sodium-ion batteries and lithium-ion batteries

Sodium-ion batteries and lithium-ion batteries "dance"

Sodium-ion batteries and lithium-ion batteries "dance" "Sodium-ion batteries are not a substitute for lithium-ion batteries, but are complementary to lithium-ion batteries, alleviating the anxiety of lithium resources in the power battery industry and preventing the future from getting stuck." Currently, secondary batteries are mainly lead-acid batteries and lithium-ion batteries. Lithium-ion batteries are undoubtedly the best in secondary batteries. However, with the widespread popularity of electrification, the shortage of reliance on overseas lithium resources has become increasingly prominent, and it is difficult to complete the important task of my country's energy reform by relying solely on lithium-ion batteries. It is urgent to innovate another technical route. Sodium ion batteries have the advantages of low cost, long life and high safety performance. Not only can it become a supplement to lithium-ion batteries to a certain extent, but also alleviate the shortage of lithium resources. It can also gradually replace lead-acid batteries with serious environmental pollution to ensure my country's energy security and sustainable social development. The Institute of Physics of the Chinese Academy of Sciences has made many attempts in the development of sodium ion batteries. In terms of cathode materials, it is the first time that the Cu2+/Cu3+ redox couple, which is inactive in lithium ion batteries, has electrochemical activity in sodium ion oxide. Based on this, a ternary cathode material of copper, iron and manganese was designed, which has excellent stability, electrochemical performance, and lower cost. The invention patent has been authorized by China, Japan, the United States and the European Union at the same time. In terms of anode materials, the Institute of Physics focuses on carbon materials, aiming to develop a low-cost amorphous carbon anode material, and proposes to use anthracite, a cheap precursor, to become an amorphous carbon material. Now it can achieve 260 Ah/kg, taking into account cycle life and cost. In addition to the advantages of abundant reserves and low cost, sodium ion batteries also have the advantages of easy manufacturing, low cost, high safety, long life, wide temperature range and high rate. The application scenarios are mainly for fields below 150Wh/kg, including various energy storage, electric bicycles, and low-speed electric vehicles.

The difficulty of battery electrolyte VC additives

The difficulty of battery electrolyte VC additives

The difficulty of electrolyte VC additives   Introduction:Vinylene carbonate (VC) is a common SEI film forming additive. VC polymerizes on the surface of the negative electrode in a lithium ion battery to form a dense SEI film, thereby preventing further reduction and decomposition of the battery electrolyte on the surface of the anode electrode.   Since the beginning of this year, the supply of electrolyte additive VC has continued to be tight, and the VC additive gap has continued to grow. Some electrolyte additive manufacturers have placed VC orders in the first half of 2022.   At present, the quotation of VC bulk orders has soared to 270,000/ton, an increase of 68%-80% from the average market price of 150,000 to 160,000 last year. And VC manufacturers have the same words, "The core issue now is not price, but production capacity."   VC additives are mainly used to improve the capacity and cycle life of batteries. As the proportion of VC added to lithium iron phosphate batteries is much higher than that of NCM batteries, as the production and sales of lithium iron phosphate continue to pick up, the supply of VC continues to increase.   The preparation method of VC additive is relatively open, but the purity of the product is required to be high, because traces of impurities may affect the performance of the lithium battery.   At the same time, the production of VC additives has a certain degree of danger, and has high requirements for safe production and environmental protection. The relevant management departments have strict requirements for the construction, commissioning, and operation of projects involving hazardous chemicals.   It is worth mentioning that previously, due to less market demand for VCs, fierce price war competition, and strict control of production under environmental supervision, a number of VC manufacturers cut production and stopped production last year. It is more difficult to resume production in the later stage, which greatly reduces the overall supply of VC.   In order to ensure the supply of production capacity, Hankang Chemical (Xinzhoubang Holding Subsidiary), Zhejiang Tianshuo (Tianci Materials Holding Subsidiary), Suzhou Huayi (October Co., Ltd.), Huasheng Lithium Battery, Yongtai Technology, etc. are all in Accelerate the expansion of the deployment of additives. However, limited by VC's technology, patent barriers, and process requirements, it is difficult to expand production. It is expected that the VC gap may continue until the second half of next year.

CATL's long-term order locks in lithium hexafluorophosphate

CATL's long-term order locks in lithium hexafluorophosphate On May 28, Tinci Materials announced that Ningde Kaixin, a wholly-owned subsidiary, and Ningde Times signed the "Material Supply Framework Agreement", stipulating that Ningde Kai will be within the validity period of the agreement (from the effective date of the agreement to June 30, 2022). Xin supplied CATL with an amount of electrolyte corresponding to the expected usage of 15,000 tons of lithium hexafluorophosphate (up or down not more than 20% can be negotiated by both parties). According to industry estimates, based on a single ton of electrolyte demand of 0.135 tons of lithium hexafluorophosphate, 15,000 tons of lithium hexafluorophosphate corresponds to about 110,000 tons of electrolyte, which can support 100±20% GWh lithium battery demand. This means that CATL's power battery capacity demand can reach 100GWh by the end of June 2022. CATL locks in the electrolyte supply of Tinci materials and the price of lithium hexafluorophosphate through long-term orders and advance payments, which fully reflects the increase in the bargaining power of lithium hexafluorophosphate, and further reflects the current situation that downstream demand is strong and the supply of lithium hexafluorophosphate products exceeds supply. Industry data shows that on May 19, the market price of lithium hexafluorophosphate rose again, quoting 270,000-310,000 yuan/ton. Since the beginning of this year, the domestic price of lithium hexafluorophosphate has risen from 110,000 yuan/ton to the latest 270,000 yuan/ton, an increase of over 145%, a 4-year high. At the same time, companies including Duo Fluoride, Tianji, Jiujiu Jiu and other companies have substantially increased their lithium hexafluorophosphate quotations. For example, Tianji announced in late April that the price of lithium hexafluorophosphate products will be increased by 15%-20% based on the existing quotations. It is expected that demand will continue to pick up in 2021, and the gap between supply and demand will widen. The wave of price increases will continue until 2022, especially when new energy vehicles enter the peak production and sales season in the second half of 2021. Prices are expected to continue to rise and continue to consolidate at a high level.
Electrolyte Fluorinated Lithium Salt LIFSI Become

Electrolyte Fluorinated Lithium Salt LIFSI Become "new force"

Electrolyte fluorinated lithium salt LIFSI --"new force"   As the "blood" of lithium batteries, electrolyte is essential for performance such as energy density, high and low temperature, cycle life, and safety. In the electrolyte, the solute lithium salt determines its basic physical and chemical properties, so it has also become a key variable that affects the performance of the battery.   Under the general trend of high-voltage and high-nickel power lithium batteries, the introduction of new lithium salts and additives to optimize the electrolyte formulation, and thereby empower the overall performance of the battery, is becoming the consensus of domestic and foreign battery companies.   Aiming at new opportunities in the upstream lithium salt field brought about by the evolution of power lithium battery technology, a number of emerging lithium salt and additive companies in China have begun to grow rapidly and have become "new forces" with great potential and stamina for the development of the industry.    Tianzhu Hong Fluoride Lithium Industry is one of them. Figure1: Tianzhu Hong Fluoride Lithium Industry “In the next few years, the market application window for new lithium salts represented by LiFSI is rapidly opening, and companies with technical reserves and rapid industrialization capabilities will enter the fast lane of rapid development.” This is the judgment of Cao Bin, chairman of Hong Fluoride Lithium.   Up to now, Macrofluorolithium has successfully realized the industrial production of lithium hexafluorophosphate, lithium difluorophosphate, lithium difluorooxalate borate, lithium tetrafluoroborate, and lithium bisoxalate borate. At the same time, it has made a forward-looking layout in the industrialization of the new lithium salt LiFSI.   In the short term, due to technical difficulty and high cost, LiFSI has not been directly used as a solute lithium salt, but as a solute additive mixed with LiPF6 for use in the electrolyte of a ternary power battery to improve performance.   Compare with LiFSI and LiPF6   Compare Item LiFSI LiPF6 Basic Substance  Molecular weight 187 152 Electric conductivity High slightly lower  Heat stability High Low Hydrolyzability Hydrolysis resistance, no hydrofluoric acid production Easily hydrolyzed to produce hydrofluoric acid Battery Performance Cycle life Long Short High temperature performance Good Bad Gas expansion Suppress battery swelling The battery swells Safety High Big safety hazard But in the medium and long term, with the realization of large-scale production and substantial cost reduction, LiFSI will gradually replace LiPF6. Start a new era of lithium salt. Judging from the market trends in recent years, more and more companies are turning their attention to LiFSI.
Large size cylindrical battery

Large size cylindrical battery

Large size cylindrical battery "turmoil" The breakthrough of full-tab technology and the parallel ternary/iron-lithium technology have made the advantages of the large cylinder in terms of performance, cost and safety more obvious. The broadening of the application scenario boundary and the follow-up of head battery companies also allow large cylindrical batteries to regain a place in the power battlefield. After the Tesla battery day, the 4680 non-electrode (also known as all-electrode) large cylindrical technical route was proposed. Immediately afterwards, a number of OEMs and battery companies accelerated their actions in the field of large cylindrical batteries. As one of Tesla's three major power battery suppliers, CATL is also actively deploying large cylindrical batteries, mainly targeting the two-wheeled vehicle market. At the same time, it does not rule out the introduction of large cylindrical batteries into the passenger car field. In terms of high-end passenger cars, in addition to having Tesla's market endorsement, Porsche also made it clear that cylindrical batteries are an important future direction for power batteries, and it is studying high-power, high-density batteries. The clear market trend is down, and battery companies are quickly following up. In addition to Panasonic and LG have begun to deploy 4680 battery production lines for Tesla, domestic battery companies have also unveiled the progress of 4680 batteries. BAK Chief Scientist Lin Jian said that BAK is cooperating with customers on the application and development of all-tab large cylindrical batteries. 4680 battery cell samples are expected to be mass-produced within this year, and mass production is expected to start in 2023, and will be the first to be applied in the car electronics market. Ji Yajuan, director of Yiwei Lithium Energy Basic Materials and Technology Research Office, also said that the company has deployed two major models of 46800 and 46950 in large cylindrical batteries, and will gradually promote large cylindrical batteries in the market after 2023. After the completion of large-scale mass production and initial market introduction, the market competition of the large cylinder may have just begun.

BAK overall arrangement full tab 4680 cylindrical battery

BAK overall arrangement full tab 4680 cylindrical battery At the 2021CIBF battery exhibition that opened on March 19. Dr. Lin Jian, chief scientist of BAK Battery, revealed that BAK is cooperating with a number of domestic and overseas customers on the application and development of all-terminal large cylindrical batteries. 4680 battery cell samples are expected to be mass-produced within this year. Compared with the previous 18650 and 21700 batteries, the large cylindrical battery represented by 4680 adopts the full tab technology, which can not only increase the size of the single battery cell and increase the space utilization rate under the premise of ensuring the safety of the entire battery pack, it can also increase the mileage of the vehicle. At the same time, the full tab technology can also solve the power performance bottleneck of the cylindrical cell. This is also the main reason why Tesla has set its sights on the 4680 battery. It is reported that while BAK is strategically exploring large-size cylinders, it has also deployed full battery tab technology and formed a unique full tab technology route in 2019. In the future, full tab large cylindrical batteries for high-end models will become the core product of BAK's automotive electronics applications. As far as the industry is concerned, BAK believes that mass production of large cylindrical batteries is expected to begin in 2023, and large cylindrical batteries will be used in the car electronics market at the earliest. In terms of industrialization progress, BAK revealed that it has begun planning a mass production base for large-size cylindrical batteries, and it is expected to achieve mass production of large cylindrical batteries in the next two years.

AOTELEC Wish You a Happy Chinese Lunar Year of 2021

Happy Chinese Lunar Year of 2021 Thank you for all the valued customers, in the year of 2020, we faced terrible pandemic of COVID-19, but we still worked well and we believe that our cooperation will keep going and be better.  Here we want to inform you that the Chinese New Year holidays is coming, we will be off from 6th-20th february 2021, during this period, we may not avaible for replying you on time, but you can still contact the sales person by email. We will try best to reply you in time. Here are some FAQ about Chinese New Year: 1. Is Chinese New Year a Public Holiday? Chinese New Year is a public holiday. It is a day off for the general population, and schools and most businesses are closed. 2. What Do People Do? Many people clean their homes to welcome the Spring Festival. They put up the red posters with poetic verses on it to their doors, Chinese New Year pictures on their walls, and decorate their homes with red lanterns. It is also a time to reunite with relatives so many people visit their families at this time of the year. In the evening of the Spring Festival Eve, many people set off fireworks and firecrackers, hoping to cast away any bad luck and bring forth good luck. Children often receive “luck” money. Many people wear new clothes and send Chinese New Year greetings to each other. Various activities such as beating drums and striking gongs, as well as dragon and lion dances, are all part of the Spring Festival festivities. 3. Background According to historical documents, on the day when Shun, who was one of ancient China’s mythological emperors, came to the throne more than 4000 years ago, he led his ministers to worship heaven and earth. From then on, that day was regarded as the first day of the first lunar month in the Chinese calendar. This is the basic origin of Chinese New Year. China adopted the Gregorian calendar in 1911, so Chinese New Year was renamed the Spring Festival.

Advanced methods for intelligent manufacturing of lithium battery electrodes

The expansion plan of power battery drives lithium battery equipment. The existing relatively clear battery expansion plan corresponds to a total of 198.1 billion yuan in lithium battery equipment procurement needs in 2019-2025; the average annual growth rate of lithium battery equipment investment is about 23%, and overseas equipment is higher than China. From the product level, the core equipment of the front-end process mainly includes a battery coating machine and a battery electrode roller press. Among them, the technical indicators of the coating machine include coating speed, width, thickness and precision, deviation correction, tension control and drying technology. The current localization rate has reached 70-80%, and the core components of high-precision control such as the coating head still need to be imported. Based on this, Li focused on the three major product series of Jin Yinhe lithium battery slurry twin-screw continuous automatic production line, double-sided simultaneous coating machine, and two-stage simultaneous roll-pressing and battery electrode slitting machine. Among them, the battery slurry twin-screw continuous automatic production line currently has 85 normal production lines, including models such as 65 machines, 75 machines, 95 machines, and 125 machines. Li said that the equipment's single production line requires only 1-2 people, and produces 600-2500L/h slurry per hour, with a capacity covering 1-9GWh, realizing continuous conveying and metering, with an accuracy of 0.2%, and the same capacity as the conventional mixer technology. By comparison, it can save 1.4-91.9 million kilowatt-hours of electricity per year. The Jin Yinhe double-sided simultaneous coating machine will be mass-produced and sold in 2020. Compared with equipment with the same capacity, the reduction of one layer of oven effectively reduces energy consumption and energy saving by 30-40%; at the same time, the procurement cost is reduced by about 10-20%, and the operating cost is reduced by 30% the above. In addition, the height of the equipment is reduced by 1/3, and the transition device in the unwinding and unwinding area is eliminated in the length direction, saving about 6m of length space with a single device. Finally, Li emphasized that the two-stage simultaneous roll pressing and slitting machine is designed to increase the compaction density of pole pieces and solve the problem of high-pressure rolling of pole pieces. This product is also the first domestic application to be used in the lithium battery industry; Problems such as sheet bounce and overpressure on the pole surface; in a true sense, the problem of wrinkling in the foil area of the high-speed stripe roller pressure is solved.

In the first October, the output of electric bicycles was 25.48 million, a year-on-year increase of 33.4%. Among them, the monthly output of electric bicycles in October was 2.499 million, a year-on-year increase of 29.9%. In terms of benefits, the operating income of electric bicycles was 75.99 billion yuan, an increase of 26.9% year-on-year, and the total profit realized was 3 billion yuan, an increase of 30.5%. Increased demand on the To B side such as shared bicycles and takeaways has boosted overall sales. Since April, the domestic electric bicycle market has recovered rapidly and started a year-on-year growth rate of 50% for 6 consecutive months. The increase in the output of electric bicycles releases the corresponding demand for lithium batteries, especially the high concentration of electric bicycle application fields such as ToB end, which is more suitable for the promotion of battery swap mode, and further increases the demand for lithium batteries. It is expected that with the emergence of the replacement wave after the transition period of the new national standard and the rapid development of superimposed sharing/replacement, the shipment of bicycle lithium battery will increase to 8.45GWh in 2020, a year-on-year increase of 55%; In 2021, the penetration rate of lithium batteries will further increase, exceeding 30%.
