A VO-flyash composite electrode for a lithium/polymer battery (LPB) was developed. We investigated XRD diffraction and electrochemical properties of vanadium oxide (VO)-flyash composite with polyvinylidene (PVDF)/polyacrylonitrile (PAN)-based polymer electrolyte as a function of mixing ratio. The discharge capacity of VO-flyash with 50 Wt-% V2O5 in PVDF-PAN-PC(5)EC(5)iClO(4) electrolyte was 150 and 128 mAh/g at 1 and 10 cycles, respectively. The discharge capacity of VO-flyash with 85 wt.% V2O5 was 195 mAh/g at 10 cycles. The capacity retention of VO-flyash anode with 3 Wt-% V2O5 was higher than that of VO-flyash cathode with 85 Wt-% V2O5. The VO-flyash with 3 wt.% V2O5 composite anode in PVDF/PAN-based electrolyte shows good capacity with cycling. (C) 2003 Elsevier Science B.V. All rights reserved.
