Application

Bis(trifluoromethane)sulfonimide lithium salt (LiTFSI) is a source of lithium (Li+) ions that is extensively used as an organic electrolyte in lithium-ion batteries and capacitors. LiTFSI is also used as an additive to enhance the hole conductivity in perovskite and dye-sensitized solar cells.
