Compared with other rechargeable batteries, lithium-ion batteries have the advantages of high energy density, high operating voltage, long cycle life, and low self-discharge. At present, small-capacity lithium-ion batteries have been successfully used in mobile phones, digital cameras, and notebook computers and large-capacity high-power lithium-ion power batteries also have good application prospects. However, when the existing lithium-ion battery is applied in a high-temperature environment, side reactions easily occur to generate gas, which causes the battery to expand in thickness and affect normal use. With the continuous deepening of practical applications, the demand for high energy density lithium-ion batteries is becoming more and more urgent. Thereby increasing the energy density of the lithium-ion battery, the electrolyte has an important influence on the performance of the battery.
Electrolyte is susceptible to oxidation reaction, especially in high temperature applications. By using some additives, the storage performance of the battery can be improved, but the impedance of the battery has been greatly increased, and its rate performance and cycle performance have deteriorated. Therefore, in order to meet the requirements for the use of high-voltage batteries, it is indeed necessary to develop a new type of automated production line for the production of lithium batteries to improve the high-temperature performance of lithium-ion batteries without degrading the battery’s rate and cycle performance.
Lithium battery automated production line can realize full automatic code scanning-injection-weighing-rehydration-sealing operation in the super purification glove box, realizing efficient and completely unmanned automated production, greatly saving labor costs, greatly improving productivity and product quality and finished products Rate to maximize customer benefits.
