Solid polymer electrolyte and electrolytic cell employing the same

A solid polymer electrolyte for an electrolytic cell is prepared by a sol-gel process in which an active metal ion conducting liquid electrolyte, e.g. a lithium-ion electrolyte, containing a salt which is stable in the presence of water, e.g. lithium bisperfluoroethanesulfonimide, LiN(SO2C2F5)2, is...

Zusammenfassung:A solid polymer electrolyte for an electrolytic cell is prepared by a sol-gel process in which an active metal ion conducting liquid electrolyte, e.g. a lithium-ion electrolyte, containing a salt which is stable in the presence of water, e.g. lithium bisperfluoroethanesulfonimide, LiN(SO2C2F5)2, is admixed in aqueous solution with an alkoxide, e.g. silica alkoxide, to form a liquid precursor which is added to the electrolytic cell between the anode and cathode thereof and allowed to solidify in situ to form the solid electroyte.
