Effects of CO2 accumulation during cycling of a Li–O2 battery on the transition of discharge product and performance fading

This study reveals an important mechanism of performance fading of Li–O2 battery and develops an efficient approach to increase the cycle life, which has thrown new insight into the design and construction of Li–O2 batteries with long lifespan.Graphical abstractA thorough investigation on the effects of CO2 accumulation during cycling of a Li–O2 battery employing RuO2/rGO cathode leads to realize a strategy to preload CO2 absorbent (CaO) into the battery, which has prolonged significantly the cycle lifespan.
