As the most popular power source for energy storage equipment, lithium-ion batteries (LIBs) offer advantages such as high-energy density, high power, and long cycle life. However, the performance of LIBs is hindered by increased impedance and reduced lithium-ion diffusion at low temperatures, leading to poor electrochemical activity and decreased capacity. This review comprehensively examines the factors affecting the performance of LIBs at low temperatures and highlights methods and mechanisms for improving the capacity of various electrode materials.
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.
