In electrical performance testing, high-temperature testing is an essential part, including high-temperature storage, high-temperature cycling, and thermal chamber testing. Although we will not discuss extreme testing conditions such as thermal shock for now, thermal runaway caused by thermal chamber testing is a destructive test. Under normal high temperature conditions, the battery cells stored at high …
