Lithium-ion battery (LIB) cells are prone to overdischarge or overcharge when connected in series or parallel as a module or pack for large-format applications, such as electric vehicles (EVs) because of variations in battery capacities and difficulty in maintaining similar state-of-charge (SOC) of every single battery.
Furthermore, the degradation effect is analyzed by analyzing the incremental capacity-differential voltage curves. During the high current cycling process, lithium inventory decreases significantly. Besides, the active material decreases when the battery degrades to a certain level.
indicated that the LIB could fail when it was over-discharged above a critical degree. Fig. 10 shows several typical moments during the burning process of LIB a ected by a 2 kW power electric heater. The batteries were the ones experiencing failure induced by 2C overcharge/over-discharge. The batteries were placed upon the supporting mesh.
The cathode materials and anode materials after over-discharge cycling are characterized by SEM technology. Finally, the state of health (SOH) of batteries were estimated based on the IC peak, lithium-ion diffusion time constant and relaxation voltage curve characteristic.
Compared to the fire behaviors of the overcharged LIB, much moderate fire behaviors were observed for the failed LIB due to over-discharge, and it took more time to be ignited. Therefore, the burning process of the over-discharged LIB lasted much longer.
As described in Equation (4), when the battery cells are charged/discharged with large current rates, rapid heat generation quickly reaches the SEI film decomposition temperature, which induces the chain thermal-electrochemical reactions, finally triggering TR.
