Abstract:
With the rising of energy requirements, Lithium-Ion Battery (LIB) have been widely used in various fields. To meet the requirement of stable operation of the energy-storage devices in extreme climate areas, LIB needs to further expand their working temperature range. In this paper, we comprehensively summarize the recent research progress of LIB at low temperature from the perspectives of material and the structural design of battery. First, the fundamental reasons of limiting low-temperature performance of LIB are analyzed. Then, the rational strategies for improving the low-temperature performance of LIB are discussed from four aspects: the research and optimization of electrolyte, the modification and exploitation of electrode materials, the development of new types of battery system as well as the design of Battery Thermal Management System (BTMS). Finally, the urgent problems to be solved in low-temperature LIB research are summarized, and the feasible research direction is suggested for the development of a new generation of low-temperature LIB.
