Abstract
It has been demonstrated that LiCoO2 is a very attractive cathode acti ve material for lithium rechargeable cells. Poly(acrylonitrile) (PAN)- based polymer electrolyte is used for Li/LiCoO2 cells. PAN-based polym er electrolyte shows ionic conductivity of the order 1 mS cm(-1) at ro om temperature, irrespective of time evolution, and wide electrochemic al stability up to 4.3 V (versus Li+/Li). An LiCoO2 composite cathode containing 4 wt.% conductive material displays a good cycling performa nce. From a.c. impedance results, the interfacial resistance of Li/LiC oO2 cells is dominated by the passive layer formed at the lithium/poly mer electrolyte interface.
