Research Progress in Low Temperature Performance of Power Lithium-ion Batteries
Lithium-ion batteries are widely used in intelligent electronic devices,electric vehicles,green energy storage systems and other fields.However,due to the obvious capacity and power loss,charge and discharge difficul-ties,cycle life decline,and safety decline of the battery at low temperatures,the performance decline is more signifi-cant than that at high temperatures,which restricts further development.Therefore,according to the thermal manage-ment of intrinsic materials and PCM batteries,this paper introduces the progress of low-temperature power batter-ies,and summarizes the shortcomings of current low-temperature power batteries.
