Anwendungen & Verwendung
Verwenden
Lithium trifluoromethanesulfonate is mixed with ceramic filler to prepare polyethylene oxide films in order to improve the electrochemical and mechanical characteristics of the membrane, which is used in the lithium batteries. It acts as a doping salt used in the preparation of nano manganese-composite polymer electrolytes.
