Why does a lithium-ion battery overcharge or over-discharge?
A lithium-ion battery (LIB) may experience overcharge or over-discharge when it is used in a battery pack because of capacity variation of different batteries in the pack and the difficulty of maintaining identical state of charge (SOC) of every single battery. A series of experiments were established to investigat
What are the abuse tests for lithium-ion batteries?
The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.
How is a single lithium ion battery overcharged?
In the standards or regulations, the overcharge performance of single lithium-ion battery is evaluated through several overcharge tests, during which a controlled current is applied to the tested battery (e.g. 1/3 C) up to a set of charge limits (e.g. 2.0 SOC, 1.5 times the upper cut-off voltage).
Why is a battery overcharge test important?
Most battery safety standards require this test as it is the most hazardous abusive condition leading to TR. Also, it represents situations that could happen in battery safety accidents . Thereby, the overcharge test is relevant to perform to enable safer LiBs.
What is a Lib overcharge test?
Overcharge test The overcharge test evaluates the ability of a LiB to withstand an overcharge condition. The overcharge test procedure is also used for testing the functionality of the overcharge/over-discharge protection system . The goal is to charge the cell beyond its voltage limits recommended by the manufacturer.
How to improve overcharge performance of lithium-ion batteries?
Rupture of the pouch and separator melting are the two key factors for the initiation of TR during overcharge process. Therefore, proper pressure relief design and thermal stable separator should be developed to improve the overcharge performance of lithium-ion batteries.
