Abstract

A lithium electrochemical cell is provided that provides many cycles with loss in capacity. The cell contains an ion conducting solid polymer electrolyte and an electronically conductive, anion-intercalating polymer cathode.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A solid state electrochemical cell including metallic lithium as an anode, (PEO) 20  (LiCF 3  SO 3 ) 1  (LiN[CF 3  SO 2  ]) as a solid polymer electrolyte and and poly (3-methylthiophene as a solid polymer cathode. 
     
     
       2. A solid state electrochemical cell including metallic lithium as an anode, (PEO) 20  (LiCF 3  SO 3 ) 1  (LiN[CF 3  SO 2  ] 2 ) 1  as a solid polymer electrolyte and poly 3-methylthiophene-BF 4  as a solid polymer cathode. 
     
     
       3. A solid state electrochemical cell including metallic lithium, as an anode, PEO) 20  (LiCF 3  SO 3 ) 1  (LiN[CF 3  SO 2  ] 2 ) 1  as a solid polymer electrolyte and poly(3-methylthiophene-CF 3  SO 3  as solid polymer cathode. 
     
     
       4. A solid state electrochemical cell including metallic lithium as an anode, (PEO) 20  (LICF 3  SO 3 ) 1  (LiN[CF 3  SO 2  ] 2 ) 1  as a solid polymer electrolyte, and poly(3-methylthiophene)-N(CF 3  SO 2 ) 2  as a solid polymer cathode.
