- Abstract
LaSrMnO ( x = 0.1∼0.4) catalysts for primary and rechargeable zinc-air batteries have been successfully synthesized by the citrate method and their electrochemical properties measured. The materials can catalyze both ORR and OER, and the one with ideal composition of LaSrMnO catalyst exhibits the highest catalytic activity and durability in alkaline medium. The resulting primary zinc-air cell shows a peak power density of 146 mW cm at 235 mA cm. The secondary cell exhibits a charge-discharge voltage gap of 1.0 V at 10 mA cm, which is highly stable over many charge-discharge cycles.
