    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 Background According to historical documents, on the day when Shun, who was one of ancient China’s mythological emperors, came to the throne more than 4000 years ago, he led his ministers to worship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.

    Electric bicycle production in October increased by 30% year-on-year

    Electric bicycle production in October increased by 30% year-on-year On December 9, the Ministry of Industry and Information Technology issued the "Operation of the Bicycle Industry from January to October 2020". 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%.
