A kind of electrode of lithium cell preparation method comprising interface stability polymer material and the application in solid state lithium battery

The invention discloses a kind of electrode of lithium cell preparation method comprising interface stability polymer material and its applications in solid state lithium battery.It is characterized in that interface stability polymer material is polymerized thylene carbonate vinyl acetate（PVCA）Or its copolymer.Free radical, which causes monomer, to carry out bulk polymerization and obtains polymer, and interface stability polymer material can form cover film in electrode surface, can effectively inhibit in charge and discharge process the destruction of electrode material and solid electrolyte in the decomposition of positive and negative pole surface.Meanwhile the polymer material can form stabilized protection course on lithium metal surface, inhibit the growth of Li dendrite, and then improve the cycle performance of solid state lithium battery.The present invention also provides the preparation methods of above-mentioned electrochemically stable polymer material, and use the solid state lithium battery of its assembling.
