Lithium tetrafluoroborate is a mild Lewis acid, used for Diels-Alder reaction; ethylene oxide ammonolysis catalyst, used as a conductive salt for primary lithium batteries or secondary lithium ion batteries.

Lithium bis(fluorosulfonyl)imide;

Imidodisulfuryl fluoride lithium salt

CAS NO.: 171611-11-3

EINECS NO.: 686-526-7

Molecular Formula: LiN(SO2F)2

Molecular Weight: 187.07

Appearance: White powder

Melting Point(°C): 124

Lithium bisfluorosulfonyl imide can be used as an electrolyte additive for lithium-ion batteries. It can be used in the electrolyte of rechargeable lithium batteries, which can effectively reduce the high and low temperature resistance of the SEI layer formed on the surface of the electrode plate at low temperatures, and reduce the capacity loss during the placement process, provide high battery capacity and electrochemical performance of the lithium battery. It can also be used as an electrolyte for a primary battery; it can be used as a polymerization catalyst; it can also be used as an antistatic agent in the industrial field.
