As an emerging industry, lithium-ion polymer batteries have developed rapidly in the recent two years. More and more companies apply lithium-ion batteries to their products. Customization of lithium-ion battery pack came into being in this environment. Lithium-ion batteries are used in more and more fields, and more and more companies want to customize lithium-ion batteries.

    The customized use of lithium-ion batteries is a process of the charge-discharge cycle. The charge-discharge system, such as the size of the charge-discharge current, the choice of cut-off voltage, and the charge-discharge mode, also have an important influence on the cycle life of the Li-ion battery. Blindly increasing the working current of the battery, increasing the charging cut-off voltage, and reducing the discharge cut-off voltage will reduce the performance of the lithium-ion battery.

    Lithium-ion battery aging can be said to be the most indispensable process in lithium-ion battery customization. The important purpose of the activity stage of lithium-ion battery customization is to fully activate the electrolyte and active substances in the battery, so as to achieve stable electrochemical performance. The aging of lithium-ion batteries is an important contribution to this goal.

    At present, there are hundreds of domestic lithium-ion battery manufacturers, but few of them have the capacity to produce a complete set of powerful lithium-ion batteries. There is a lack of core technology for customized lithium-ion batteries. Many core technologies still rely on foreign patents and equipment, which makes the price of customized lithium-ion batteries raised.
