separation degree and achieves a more balanced donor number and tuned self-cleaning intensity for a reinforced SEI. Consequently, the fast charging/discharging capability of lithium metal batteries with this self-folded lithium salt is progressively improved.
通过在N原子附近连接一个吸电子磺基,Li−N的距离从
LiFEA中的2.069 Å调整到LiETFSI中的4.367 Å,从而增强了离子分离程度,实现了更平衡的供体数量和调整的自清洁强度强化
SEI。因此,采用这种自折叠
锂盐的
锂金属电池的快速充放电能力逐渐提高。
