Application of poly-p-phenylene as positive electrode active material for Al secondary battery with ambient-temperature molten salt electrolyte

Abstract

Al secondary batteries with the ambient-temperature chloroaluminate molten salt electrolyte have been developed. Various conducting polymers were evaluated in order to improve the positive electrode. Among them, the electrochemical characteristics of poly-p-phenylene (PPP) film were the most excellent. In the case of the charging below 50 mAh g-1, the charge/discharge efficiency was around 100%. It was found that the PPP film electrode operated well as the positive electrode for Al secondary battery. Al, Secondary Battery, Poly-p-phenylene, Ambient-Temperature Molten Salt.
