Abstract

A disiloxane-functionalized ionic liquid based on a phosphonium cation and a bis(trifluoromethylsulfonyl)imide (TFSI) anion was synthesized and characterized. This new ionic liquid electrolyte showed good stability with a lithium transition metal oxide cathode and a graphite anode in lithium ion cells.
