Lithium-ion Battery Heavy Impact Test

Lithium ion batteries have become one of the main power sources for portable electronic products such as mobile communications and laptops due to their high specific energy and high voltage. However, under abusive conditions such as heating, overcharging, over discharge short circuit, vibration, compression, etc., lithium-ion batteries may experience incidents such as fire, explosion, and even personal injury, resulting in a large number of lithium-ion batteries being recalled.
Therefore, how to improve the safety performance of lithium-ion batteries has become a key issue in their development. Currently, many countries or testing institutions have developed relevant safety testing methods for lithium-ion batteries. Lithium ion batteries must pass safety tests to reduce their usage risks. The international standards related to the safety of lithium-ion batteries mainly include IEC 62133, IEC 62281, UL 1642, UL 2054, UN 38.3, etc.
