METHODS FOR TESTING LITHIUM ION BATTERY AND EVALUATING SAFETY OF LITHIUM ION BATTERY |
摘要 |
A method for testing a lithium ion battery is disclosed. An under-test lithium ion battery including a cathode active material is provided. A reference voltage value is set according to the cathode active material. The under-test lithium ion battery is over charged, while an actual voltage change of the under-test lithium ion battery is tested during the over charging. A maximum voltage value is recorded before a first decrease in the actual voltage change of the under-test lithium ion battery during the over charging. The maximum voltage value is compared with the reference voltage value. A method for evaluating a safety of a lithium ion battery is also disclosed. |
