低温钠离子电池中硬炭负极性能的提高策略
A review of ways to improve the performance of hard carbon anodes in low-temperature sodium-ion batteries
摘要
Abstract
Because of their excellent low-temperature(-15 to-40 ℃)tolerance,sodium-ion batteries are emerging as a complement to lithium-ion batteries for use in extremely cold environments(e.g.high-latitude areas).Hard carbon has a high low-voltage sodium stor-age capacity and a good initial efficiency,making it one of the most promising anode materials for sodium-ion batteries.It has a complex structure,featuring closed pores,nano graphitic domains,and surface functional groups.The sodium storage sites in hard carbon are re-viewed as are the widely accepted sodium storage mechanisms.The main factors contributing to the de-gradation of the good low-temperature performance in hard carbon anodes are considered,including sodium dendrite formation,low ion diffusion rates,and surface-side reactions.Fi-nally,strategies to increase the low-temperature sodium storage performance of hard carbon anodes are summarized,including bulk structure design,and improvements in interfaces and cut-off voltage.Guidance is provided for improving the low-temper-ature performance of hard carbon anodes to accelerate the development of these batteries.关键词
