α-MnO2/MWCNTs as an electrocatalyst for rechargeable relatively closed system Li-O2 batteries.

Herein, a new, relatively closed system Li-O2 (RCLO) battery, without extra oxygen being involved in the reaction during the charge and discharge process, is reported. This relatively closed system effectively solves the key issue of poor circulation caused by oxygen generation in conventional Li-O2 batteries.
