摘要:

随着新能源行业的快速崛起,锂离子电池在各个领域的应用持续激增。然而,石墨负极的商用锂离子电池的高性能只能在0 ℃以上实现,这限制了电池在低温寒冷地区的应用。为了满足锂离子电池的低温应用需求,通过分析石墨低温环境的受限因素,探究其机理并深入了解导致锂离子电池低温性能差的关键因素。重点介绍了提高低温性能的可行性策略和解决方案,从结构设计、形貌控制、表面与界面修饰、多相材料等方面综述了低温负极材料工程化的最新进展。最后,对低温石墨负极材料领域有待解决的问题进行了讨论。旨在为开发具有优异低温电化学性能的下一代LIBs提供有价值的见解和指导。

Abstract:

In recent years,with the rapid rise of the new energy industry,the application of lithium-ion batteries in various fields has continued to surge.However,the high performance of commercial lithium-ion batteries with graphite anodes can only be realized above 0 ℃,which limits the application of the batteries in low-temperature cold regions.In order to meet the demand for low-temperature applications of lithium-ion batteries,the mechanism was explored by analyzing the limiting factors of graphite low-temperature environments,providing insights into the key factors contributing to the poor low-temperature performance of lithium-ion batteries.It was focused on the feasible strategies and solutions to improve the low-temperature performance,and the latest progress in the engineering of low-temperature anode materials was reviewed in terms of structural design,morphology control,surface and interface modification,and multiphase materials.Finally,the problems to be solved in the field of low-temperature graphite anode materials were discussed.It was aimed to provide valuable insights and guidance for the development of next-generation LIBs with excellent low-temperature electrochemical properties.

Key words: lithium-ion battery, graphite anode material, low temperature performance, modification
