Constructing advanced electrode materials for low-temperature lithium-ion batteries: A review

As the most popular power source to energy storage equipment Lithium-ion battery (LIB), it has the advantages of high-energy density, high power, long cycle life, as well as low pollution output. However, owing to increased battery impedance under low-temperature conditions, the lithium-ion diffusion in the battery is reduced, and the polarization of the electrode materials is accelerated, resulting in poor electrochemical activity and a drop in capacity during cycling. This issue is greatly hindering the further advancement of LIBs. In this review, we comprehensively review the factors affecting the performance of LIBs at low temperatures and introduce key methods and related mechanisms for improving the capacity of various electrode materials. Our overview aims to fully elucidate the basic principles of the low-temperature property of LIBs from a material point of view and to facilitate the advancement of high-performance LIB electrode materials that can be used in the wide working temperature range.
