The cycle life of lithium batteries has always been one of the most important parameters for electric vehicle buyers. How does a lithium battery get old? Aging always appears together with failure, but to be precise, aging and failure are two concepts. Aging, which refers to the deterioration of power battery performance parameters over time, …

The activation stage of lithium battery pack includes precharge, formation, aging, constant capacity and so on. There are two main factors influencing the performance of lithium battery pack, namely aging temperature and aging time. What’s more, it is important that the battery tested in the aging test chamber is in a sealed state. If it …

This passage summarizes the mechanism of thermal runaway and preventive measures, which have been applied in the design and manufacturing of all battery systems. However, in practice, different material systems have different chemical characteristics, so the thermal runaway mechanism of the battery core is different. Different system designs will also lead to different system-level risks …

About salt spray test The salt spray corrosion test can evaluate the ability of salt spray corrosion to materials and their protective layers, and the comparison of process quality of similar protective layers, and also the ability of some products to resist salt spray corrosion. It is mainly used for the corrosion test of parts, …
