Abstract:
A method of preparing an electrochemical cell that comprises the steps of:(a) fabricating an electrochemical cell in the discharged state which comprises (i) an anode comprising an intercalation based carbon material, an (ii) a cathode comprising a lithiated cathodic material, and (iii) a polymeric matrix interposed between the anode and cathode which comprises an electrolyte solvent and salt; (b) placing the electrochemical cell in an environment that is maintained at an elevated temperature of at least 30Â° C.; (c) charging and discharging the electrochemical cell; (d) removing gas that is generated by the electrochemical cell in step (c); and (e) sealing the electrochemical cell.
