Abstract : The rechargeable high energy density polymer electrolyte battery utilizing a lithium anode, poly(ethylene oxide)-salt complex electrolyte and Vanadium oxide composite cathode is being investigated in this laboratory. Cycled tests indicated good adhesion at the anode/electrolyte and electrolyte/cathode interfaces, even after one-hundred deep cycles. Results are also presented on the morphological changes taking place at the cathode. A modified polymer electrolyte with relatively higher room temperature ionic conductivity has also been employed in cells at ambient temperatures. Scaled-up designs are under evaluation.
