As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects.
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.
