Abstract

The purpose of this study is to research and develop polymer secondary battery. This paper describes the first discharge characteristics of PAn/Li-Al secondary battery. PAn was prepared in $HBF_4$ aqueous solution by galvanostatic electropolymerization and then used as cathode active material. PAn/Li-Al secondary battery was prepared in 2025 coin type. Characteristics of this battery are summarized as follows. ${\bullet}$ Open curcuit voltage and discharge end voltage was 3.5V and 2.9V, respectively. ${\bullet}$ The ratio of electricities in discharge to theoretical electricities in all undoping of PAn cathode was 56% at constant current discharge of 1mA. ${\bullet}$ The capacity density, energy density and maximum power density per weight of PAn electroactive material were 56.1Ah/kg, 168.4Wh/kg and 16.9kW/kg, respectively.
