A reversible graphite-lithium negative electrode for electrochemical generators

Lithium intercalation compounds in graphite have been obtained by electrochemical methods using a solid organic electrolyte (polyethylene oxide with lithium perchlorate). Intermittent electrochemical techniques have enabled the kinetic (diffusion coefficient) and thermodynamic (enthalpy) values to be calculated. Some secondary battery cycling tests using lithium-graphite as a negative electrode are reported.
