What Are the Long-Term Effects of Regular Overcharging on Lithium-Ion Batteries?1. Increased Self-Discharge Rate3.
During a lithium-ion battery overcharge, its cathode (anode) is over-delithiumed (overlithiumed), and a series of side reactions generate [8, 9]. Those side reactions produce some heat and gas, resulting in the oxidation of the electrolyte or cathode materials, and thermal runaway occurs .
This work, for the first time, comprehensively investigates the impact of different overcharge degrees on degradation and thermal runaway behavior of lithium-ion batteries.

The effects of charging current, restraining plate and heat dissipation condition on the overcharge performance of a 40 Ah lithium-ion battery are evaluated. The batteries overcharge behaviors show only minor changes with the increase of charging current, as the TTR remains at around 113 °C and the SOC TR decreases slightly.
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.
