What is battery aging cabinet and China top 5 battery aging cabinet companies

The battery aging cabinet, as the name suggests, is an important equipment for the battery aging process. The quality of battery aging determines the safety, stability, service life and battery performance of the battery in actual use. Therefore, the battery aging cabinet is the core equipment in the battery quality control process. This article sorts out the top 5 battery aging cabinet companies in China for your reference, including CPET, Benice, ATSTECH, Wangdafu and XINDANENG.

1. What is the battery aging cabinet used for?

Generally speaking, the aging cabinet is used to simulate how long the lithium batteries such as lifepo4 battery, ternary lithium battery, etc. used in our daily life can be used.

If the customer asks how long it takes for the battery pack to be fully charged and how long it takes to fully charge, these data need to be measured with a lithium battery aging cabinet. That is, how long the simulated battery pack can be used once charged.

In fact, the principle is similar. One reason is complete wetting of the electrolyte. On the other hand, some active ingredients in the cathode active material are deactivated by some reactions, making the overall performance of the battery more stable. Many companies want to do this process and accelerate the adoption of high-temperature aging, but high-temperature aging requires attention to control time and temperature.

Because high-temperature aging will cause more active material degradation than normal temperature aging, if it is well controlled, the active components will react completely and the battery characteristics will be stable. If the adverse reaction is controlled excessively, the electrical performance will decrease, the capacity will decrease, the IR will increase, and even the possibility of liquid leakage is high.

2. What is the function of lithium battery aging cabinet?

In the past, burn-in generally referred to battery placement after the first charge after assembly and injection had been completed. It can be aged at room temperature or high temperature. Its role is to stabilize the properties and composition of the SEI film formed after the first charge. The battery aging process has electrochemical kinetic changes, which is of great help to the stability of SEI and can promote the stability of the electrochemical system.

With the rapid development of the battery industry, the definition of battery aging has quietly changed. Due to the high requirements on the battery, in theory, the battery aging cabinet is required for the four steps of battery cell forming, capacity separation, testing, and aging, and the battery aging cabinet is also required in the PACK assembly line.

Therefore, the battery aging cabinet we are talking about now is not a specific device, but a system that runs through the processes of forming, dispensing, testing, and aging detection in battery production, which are different but related to each other.

Secondly, different battery manufacturing processes and battery materials in different top 10 lithium battery companies in the world make the functional requirements of battery aging cabinets different. Therefore, the current battery aging cabinet needs to be tailored.

In actual use, considering the inconsistency between production capacity and market demand, some battery factories have adjusted the aging steps in order to increase production capacity while ensuring quality. The parameters that need to be adjusted for each production line mainly include temperature, space, time and sequence, which are designed according to the characteristics of the battery.

Therefore, the battery aging cabinet in the traditional sense is no longer suitable for the rapidly developing electric vehicle industry. To keep up with the pace, customization is needed, and customization is the best choice in terms of cost and efficiency. At present, the top 5 battery aging cabinet companies in China are also developing rapidly, and the leading industry is moving towards customized services.
