ASSESSMENT OF THIN-FILM BATTERIES BASED ON POLYMER ELECTROLYTES .1. ENERGY DENSITY

The theoretical energy density performance limits for packaged rechargeable lithium polymer electrolyte batteries of both prismatic unipolar and bipolar electrode configurations are discussed. The electrolyte is based on complexes formed between polyethylene oxide and a lithium salt, and the composite cathode is V6O13. The modeling study suggests that specific energies up to 450 Wh/kg are possible for packaged batteries based on both unipolar and bipolar cell designs. This requires the use of low density metallic or metallized plastic current collectors. © 1990.
