Therefore, the burning process of the over-discharged LIB lasted much longer. Finally, according to the physical characterization of anode materials and the mechanism of overcharge, the failure of the battery after overcharge was mainly caused by the excessive deposition of lithium ions in the anode and the formation of an internal short circuit.
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
Lithium-ion batteries are popular in modern-day applications, but many users have experienced lithium-ion battery failures. The focus of this article is to explain the failures that plague lithium-ion batteries. Millions of people depend on lithium-ion batteries. Lithium-ion is found in mobile phones, laptops, hybrid cars, and electric vehicles.
In this paper, the overcharge performance of a commercial pouch lithium-ion battery with Li y (NiCoMn) 1/3 O 2 -Li y Mn 2 O 4 composite cathode and graphite anode is evaluated under various test conditions, considering the effects of charging current, restraining plate and heat dissipation.
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).
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. 4. Conclusion
