  title = {Overcharge Protection for 4 V Lithium Batteries at High Rates and Low Temperatures},
  abstract = {<p>Overcharge protection for 4 V Li<sub>1.05</sub>Mn<sub>1.95</sub>O<sub>4</sub>/lithium cells at charging rates in excess of 1 mA/cm<sup>2</sup> (3C) and at temperatures of 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 were also examined.</p>},
