A Review on Low-Temperature Performance Management of Lithium-Ion Batteries

Abstract

Lithium-ion batteries (LIBs) are widely used in electric vehicles, energy storage power stations and other portable devices for their high energy densities, long cycle life, and low self-discharge rate. However, they still face several challenges. Low-temperature environments have slowed down the use of LIBs by significantly deteriorating their normal performance. This review aims to resolve this issue by clarifying the phenomenon and reasons for the deterioration of LIB performance at low temperatures. From the perspective of system management, this review summarizes and analyzes the common performance-improving methods from two aspects including preheating and charging optimization and then depicts the future development of methods in this regard. This review is expected to inspire further studies for the improvement of the LIB performance at low temperatures.
