For the anode, severe lithium plating happens on the anode surface during overcharge process, resulting in deteriorated thermal stability of the anode and acceleration of battery temperature rise. The overcharge-induced thermal runaway mechanism under different test conditions are revealed through detailed discussion on the TTR.
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).
Lithium ion batteries (LIBs) are booming due to their high energy density, low maintenance, low self-discharge, quick charging and longevity advantages. However, the thermal stability of LIBs is relatively poor and their failure may cause fire and, under certain circumstances, explosion.
Yuan et al. [ 7] investigated the overcharge behaviors of a large battery (32 Ah prismatic cell) by closely monitoring the internal/external cell temperature during the whole charge process. Their analysis revealed that lithium plating is one of the major causes responsible for thermal runaway during overcharge.
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.
