They established a model for uneven heat production of batteries, revealing that higher rates result in increased temperature distribution unevenness within the battery. This, in turn, leads to uneven lithium plating on the surface of the anode, accelerating battery aging.
These studies have revealed that the thermal safety of aging lithium-ion batteries is affected by the aging path. Aging changes the thermal stability of the materials inside the battery, which in turn affects the thermal safety.
M. Kassem et al. investigated the impact of different storage temperatures (30 °C, 45 °C, and 60 °C) and SOCs (30 %, 65 %, and 100 %) on the calendar aging of LFP batteries over 8 months, finding significant capacity fade at higher storage temperatures, with side reactions at the anode being the main cause.
The aging of batteries is significantly influenced by the charging and discharging rates. During the charging and discharging process, heat in the battery originates from Joule heat, chemical reactions, and phase transitions.
Additionally, the aging mechanism during high-magnification over-discharge cycles is attributed to lithium deposition in the graphite anode and the rise in transition temperature. Yang et al. investigated the effects of slight overcharge cycling on the capacity degradation and safety of LiFePO 4 batteries.
Current research primarily analyzes the aging condition of batteries in terms of electrochemical performance but lacks in-depth exploration of the evolution of thermal safety and its mechanisms. The thermal safety of aging batteries is influenced by electrode materials, aging paths, and environmental factors.
