Characteristics of Rechargeable Battery Using Conducting Poly(p-phenylene) Film

Abstract
A secondary battery utilizing electrochemically prepared poly(p-phenylene) film as cathode material in an electrolyte of LiAsF6/propylenecarbonate with Li anode was studied. A high cell voltage of 4.1 V and energy density of 300 Wh/kg (based on the weight of electroactive materials) were obtained. The cell demonstrates excellent discharge characteristics under the extremely large discharge rate of 2.5 kA/kg with an energy efficiency of more than 85%.
