A secondary electrochemical cell is made by (i) assembling a solid state electrochemical cell having an anode containing an alkali metal such as lithium as active anode material; a solid alkali metal ion conducting electrolyte, for example a polymer electrolyte comprising a complex of a solid polymer (eg poly(ethylene oxide)) and an alkali metal salt (eg LiClO4), which polymer is capable of forming donor-acceptor type bonds with alkali metal ions; and a cathode containing manganese(IV) oxide as active cathode material; and (ii) discharging the cell under conditions, eg of elevated temperature, such that the cathode material is transformed in situ into a rechargeable cathode material which may, for example be LiMn2O4. d |
