This invention is directed to a novel solid polymer electrolyte more particularly thin film terpolymer networks are disclosed that are highly conductive at ambient temperatures. This solid polymer electrolyte can be produced as a thin film (14) that results from the polymerization of three selected monomers together with a lithium salt and plasticizers. The resulting solid polymer electrolyte does have excellent mechanical properties and ionic conductivity at ambient temperatures and can be used in the fabrication of a solid state battery and other solid state electrochemical devices such as supercapacitors, fuel cells, sensors, electrochromic devices or the like. |
