Research Progress of Anode Material for Lithium-ion Batteries

Abstract

Against the backdrop of global energy transition and carbon neutrality goals, lithium-ion batteries are receiving increasing attention due to their high efficiency and large capacity storage advantages. This study systematically evaluated four mainstream positive electrode materials - LiMnO (LMO), LiCoO (LCO), LiFePO (LFP), and ternary materials. These materials have their own characteristics: LMO has low cost and good safety, but its performance may decrease in high-temperature environments; LCO has a high energy density, but is limited by the scarcity and thermal stability of cobalt resources; LFP has outstanding safety and long cycle life, but low energy density; Ternary materials exhibit excellent energy performance, especially suitable for low-temperature environments, but require high thermal management technology. The research results can help match material types according to specific needs, reduce dependence on key raw materials, enhance the sustainability of the battery industry, and provide reference for future research and development directions. Finally, this article combines energy security and environmental protection goals, and proposes corresponding suggestions for different application scenarios to promote battery technology to better serve diversified practical needs.
