ABSTRACT:
A solid state electrochemical cell comprises an anode having Li as its active material, a cathode and an electrolyte comprising a complex of a polyether with lithium.
The polyether is atactic, has a low glass transition temperature and is capable of forming a complex with Li.sup.+ ions but not with Na.sup.+ ions. An example of such a polyether is polyvinyl methyl ether. The complex may be blended with another polymer such as a poly (ethylene oxide) - LiClO.sub.4 complex to improve mechanical properties for fabrication into the electrolyte.
