Overcharge Protection for 4 V Lithium Batteries at High Rates and Low Temperatures Guoying Chen ' and Thomas J. Richardson Environmental Energy Technologies Division, Lawrence Berkeley National Laboratory, Berkeley, California 94720, USA z Abstract Overcharge protection for 4 V Li1.05Mn1.95O4/lithium cells at charging rates in excess of 1 mA/cm (3C) and at temperatures as low as -20° C was achieved using a bilayer separator coated with two electroactive polymers. High rate and low temperature overcharge protection and discharge performance were improved by employing a design in which the polymer-coated portion of the separator is in parallel with the cell rather than between the electrodes. The effects of different membrane supports for the electroactive polymers are also examined. Electrochemical Society Active Member z E-mail: gchen@lbl.gov
