Researchers directly visualize formation and disappearance of Li-O2 reaction products; insights to support development of rechargeable lithium-air batteries

Green Car Congress

This is in contrast to Li 2 O 2 particles having sizes in the range of 100 to 1000 nm formed in Li-O 2 batteries with aprotic electrolytes. This study showed that using metal oxides as the oxygen electrode could potentially enable a lithium-air battery to maintain its performance over many cycles of operation.
