A Li–O2/CO2 battery†
Abstract
A new gas-utilizing battery using mixed gas of O2 and CO2 was developed and proved its very high discharge capacity. The capacity reached three times as much as that of a non-aqueous Li–air (O2) battery. The unique point of the battery is expected to be the rapid consumption of superoxide anion radical by CO2 as well as the slow filling property of the Li2CO3 in the cathode.
