What is the role of the aging process of 502030 battery manufacturers in manufacturing lithium batteries?

　　What is the role of the 502030 battery aging process used by 502030 battery manufacturers? 502030 battery aging can be said to be the most indispensable process in the customization of 502030 battery manufacturers. Why do lithium batteries need to be aged before leaving the factory? Are there any rigid requirements for aging? In this article, 502030 battery manufacturers will talk to you about battery aging.

　　What is the role of the 502030 battery aging process?

　　The 502030 battery assembly process is roughly divided into winding, shelling, welding and other processes according to different battery specifications and models. The liquid injection process after assembly includes liquid injection and sealing. The last step is the three-step process of battery formation, aging and capacity separation.

　　The 502030 battery manufacturing process can be roughly divided into three stages: early cell manufacturing, mid-term assembly, and late battery activation. The activation stage of the battery includes battery aging.

　　Aging generally refers to the placement of the 502030 battery after the first charge and formation after the liquid injection is completed. It can be room temperature aging or high temperature aging. Both functions are to make the properties and composition of the SEI film formed after the initial charge and formation more stable. Ensure the stability of battery electrochemical performance. There are three main purposes of aging:

　　1. After the 502030 battery undergoes the preformation process, a certain amount of SEI film will be formed on the graphite anode inside the battery. However, this film has a tight structure and small pores. Aging the 502030 battery at high temperature will help to reorganize the SEI structure and form Loose and porous membrane.

　　2. After formation, the voltage of the 502030 battery is in an unstable stage, and its voltage is slightly higher than the actual voltage. The purpose of aging is to make its voltage more accurate and stable.

　　3. Placing the 502030 battery at high temperature or normal temperature for a period of time can ensure that the electrolyte can fully infiltrate the pole pieces, which is beneficial to the stability of battery performance.

　　The main functions of aging on the performance of lithium batteries are:

　　1. Improve the wettability of the electrolyte in the battery.

　　2. It can accelerate some side effects in lithium batteries, such as gas production, electrolyte decomposition, etc.

　　3. The voltage and internal resistance of the aged 502030 battery are more stable and consistent.

　　Customized aging of lithium batteries will also be affected by some external factors, namely aging time and temperature. In addition, it is also important whether the 502030 battery is in an open or sealed state during aging. The external factors of aging of lithium batteries will change due to changes in the positive electrode material of the battery cell. Because the positive electrode materials of different batteries have different properties, the degree of aging will naturally be different.

　　Summary: The aging system of lithium batteries includes room temperature aging and high temperature aging. If high temperature aging is used, aging after sealing is better. Aging is an essential process. Although the aging of lithium batteries is understood to be the loss and damage of lithium batteries, in fact it is an effective way to screen batteries with high consistency and eliminate defective products.
