Free QuoteIn 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).
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.
Therefore, it is very meaningful to study the overcharge behavior of high-power type lithium-ion batteries (maximum discharge rate 50 C). In addition, previous studies [ 9, 10, 11, 12, 13, 14, 18, 19, 20, 21] are based on the condition that the battery is continuously charged until thermal runaway.
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.
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.
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.
