Safety is a key concern for high-power energy storage systems such as will be required for electric vehicles. Present lithium ion batteries, which use a flammable organic liquid electrolyte, lack inherent safety. Our approach in solving this problem is to replace the liquid electrolyte with a liquid-free polymer electrolyte. Data of the composition of the positive electrode, charge-discharge and cycle-life capability are presented. The cell using metallic lithium anode and crosslinked polymer electrolyte P(EO/MEEGE/AGE)-LiTFSI showed a discharge capacity of 134 mAh g-1 of LiCoO2 at 60C and 140 mAh g-1 at 140C.
