The composition of lithium-ion batteries is more complex, mainly including positive/negative electrode plates, membranes, electrolytes, fluid collectors and binder, conductive agents, etc., involving reactions including electrochemical reactions of positive and negative electrodes, ionic and electronic conduction, and heat diffusion. The general process of lithium-ion battery manufacturing process is: the active substance, binder and conductive agent are mixed to prepare a slurry, and then coated on both sides of the copper or aluminum collector. After drying, the solvent is removed to form a dry electrode sheet. The electrode pellet coating is compacted and densified, and then cut or slitted. Then the positive/negative electrode sheet and the diaphragm are assembled into the battery cell, which is injected into the electrolyte after packaging, activated by charge and discharge, and finally formed the battery product. According to the shape of the core pack, it can be divided into square battery, cylindrical battery and soft battery, and the battery manufacturing process can be conventionally divided into three parts: the first part of the production process, the middle part of the assembly process and the last part of the test process. The production goal of the production section of the previous process is to complete the production of positive and negative pole pieces. Its process route includes pulping, coating, roll pressing, slitting, making, die cutting, and related equipment such as mixer, coating machine, roll press, slitting machine, making machine, die cutting machine, etc. The production goal of the assembly section of the middle process is to complete the manufacturing of the battery cell, and the technical route and production line equipment of the middle process of different types of lithium batteries are different. The essence of the middle process is the assembly process, specifically, the (positive and negative) pole sheet made by the previous process is assembled in an orderly manner with the diaphragm and electrolyte. Due to the different structure of square (roll), cylinder (roll) and soft pack (layer) batteries, there are obvious differences in the technical route and production line equipment of different types of lithium batteries in the middle process. Specifically, the main process of the middle process of the square and cylindrical battery is winding, liquid injection and packaging, and the equipment involved mainly includes winding machine, liquid injection machine, packaging equipment (shell machine, rolling slot machine, sealing machine, welding machine); The main process of the middle process of the soft pack battery includes lamination, liquid injection, packaging, and the equipment involved mainly includes lamination machine, liquid injection machine, packaging equipment, etc. The production goal of the latter process is to complete the formation and packaging. As of the middle process, the functional structure of...

Recently, our company AOTELEC organized a group building trip to Meizhou Island, Putian. This trip not only allowed us to get close to nature, but also further enhanced the cohesion and centripetal force of the team. Meizhou Island, a place known as "Penglai of the South", attracts countless tourists with its unique natural scenery and rich cultural heritage. On the day of departure, we gathered early and embarked on the journey to Meizhou Island with full expectations and a little tension. Along the way, everyone laughed and laughed, sharing each other's stories and expectations, as if they had felt the fun of group construction in advance. After arriving at Meizhou Island, we were deeply attracted by the beautiful scenery here. The breathtaking Mai Yu tidal sound, the Jiubao LAN Golden Beach known as the "Oriental Hawaii", and the mysterious Goose tail Stone and other scenic spots make us feel like we are in a fairy tale world. Everyone took out their mobile phones to record these beautiful moments, but also to keep this good in their hearts. It is worth mentioning that we also visited the Mazu Temple and Mazu Cultural Park on Meizhou Island. Here is not only the holy land of nearly 200 million Mazu believers in more than 20 countries and regions in the world, but also an important place to display Meizhou folk culture. Standing on the top of the mountain in the park, we can clearly see the magnificent Mazu Temple set off by the beautiful peaks, quiet caves and quiet forests, and the towering Mazu statue is facing the sea, graceful and kind, which makes people respectful. This team building trip not only let us relax, but also let us deeply understand the importance of the team. Through cooperation, we have learned to trust and support each other. In the challenge, we stimulate the potential, improve ourselves. I believe that in the future work, we will be more closely united together to face all kinds of difficulties and challenges.

In today's global energy transition tide, lithium batteries with its high energy density, long life, environmental friendliness and other characteristics, has become a key force to promote the development of electric vehicles, energy storage systems and all kinds of portable electronic devices. Behind all these achievements, the important role of lithium battery materials is inseparable. 1、cathode material: the core driving force of energy density The cathode material is the main source of lithium ions in lithium batteries, and its performance directly determines the energy density of the battery. Common cathode materials include lithium cobaltate, lithium iron phosphate, lithium manganate and nickel-cobalt-manganese ternary materials. Lithium cobaltate is widely used in portable electronic equipment because of its high energy density and good cycle stability. Lithium iron phosphate shines in the field of electric vehicles and energy storage with its excellent safety, long life and low cost; Nickel-cobalt-manganese ternary materials, with their high energy density and excellent comprehensive performance, have become the first choice for electric vehicles to pursue driving range. 2、anode material: the key to energy storage efficiency The negative electrode material is responsible for receiving the lithium ions migrating from the positive electrode, and its performance directly affects the energy storage efficiency and cycle life of the battery. As a traditional negative electrode material, graphite has long occupied a dominant position in the market with its stable cycle performance and good electrical conductivity. However, with the demand for higher energy density, new anode materials such as silicon-based materials and lithium titanate are gradually emerging. Silicon-based materials have the potential to improve the energy density of batteries due to their high theoretical lithium embedding capacity. Lithium titanate, with its excellent cycle stability and rapid charge-discharge ability, has shown unique advantages in energy storage systems and specific applications. 3、Electrolyte: bridge and guardian of ion transport As the transmission medium of lithium ion in lithium battery, the performance of electrolyte directly affects the ion conductivity, internal resistance and safety of the battery. Common electrolytes are mainly composed of lithium salts, organic solvents and additives. The choice of lithium salt determines the ionic conductivity of the electrolyte, and the addition of organic solvents and additives can significantly improve the chemical stability and safety of the electrolyte. By optimizing the composition and formulation of the electrolyte, the ion conduction efficiency of the battery can be further improved, the internal resistance can be reduced, and the charging and discharging performance and cycle life of the battery can be improved. 4、separator: the guardian of safety performance The separator is located between the positive...
