This work is to investigate the impact of relatively harsh temperature conditions on the thermal safety for lithium-ion batteries, so the aging experiments, encompassing both cyclic aging and calendar aging, are conducted at the temperature of 60 °C. For cyclic aging, a constant current-constant voltage (CC-CV) profile is employed.
Elevated temperatures have been shown to improve plating/stripping efficiency and to reduce the incidence of dendritic deposition 52. While the melting point of lithium (∼ 180 °C) imposes an intrinsic upper temperature limit for cells, lithium-metal batteries would have more practical challenges in the low temperature regime.
Lithium batteries function best within a specific temperature range, typically between 20°C and 25°C (68°F and 77°F). Within this range, the chemical reactions that generate power occur efficiently, allowing for optimal performance. When temperatures fall outside this ideal range, battery efficiency can decline significantly. 2.
Consequently, to address the gap in current research and mitigate the issues surrounding electric vehicle safety in high-temperature conditions, it is urgent to deeply explore the thermal safety evolution patterns and degradation mechanism of high-specific energy ternary lithium-ion batteries during high-temperature aging.
Employing multi-angle characterization analysis, the intricate mechanism governing the thermal safety evolution of lithium-ion batteries during high-temperature aging is clarified. Specifically, lithium plating serves as the pivotal factor contributing to the reduction in the self-heating initial temperature.
