A three-electrode battery is constructed for study. A low-temperature charging framework is developed. This paper proposes a novel framework for low-temperature fast charging of lithium-ion batteries (LIBs) without lithium plating. The framework includes three key components: modeling, constraints, and strategy design.
Challenges and limitations of lithium-ion batteries at low temperatures are introduced. Feasible solutions for low-temperature kinetics have been introduced. Battery management of low-temperature lithium-ion batteries is discussed.
When the dendritic Li penetrates the separator, it will cause short circuit inside the battery, leading to thermal runaway and explosion [147, 148]. Therefore, early detection and prevention of lithium plating is extremely important for low-temperature batteries.
However, commercially available lithium-ion batteries (LIBs) show significant performance degradation under low-temperature (LT) conditions. Broadening the application area of LIBs requires an improvement of their LT characteristics.
Lithium dendrites can puncture the separator and lead to internal short circuit, leading to thermal runaway . To prevent lithium plating during low-temperature charging, Ouyang et al. investigated the charging of lithium iron phosphate batteries at −10 °C.
To prevent lithium plating during low-temperature charging, Ouyang et al. investigated the charging of lithium iron phosphate batteries at −10 °C. They found that lithium plating can be avoided when the charging rate is below 0.25C and the charging cut-off voltage is less than 3.55 V.
