Characteristics of Lithium bis(fluorosulfonyl)imide (LiFSI) as conducting salt in electrolytes

Lithium bis(fluorosulfonyl)imide (LiN(SO2F3)2, LiFSI) has a high thermal stability and a high dissociation constant thus leading to increased ionic conductivity. The use of LiFSI leads to a better low-temperature performance. The LiFSI electrolyte is currently used in lithium-ion batteries as co-salt and additive.
