Mn-doped LaSrCoO perovskite catalysts with enhanced performances for non-aqueous electrolyte Li-O batteries
Mn-doped perovskite oxides, La 0.6 Sr 0.4 Co 1− x Mn x O 3 ( x = 0.05, 0.1), have been synthesized and Li-O 2 batteries based on La 0.6 Sr 0.4 Co 1− x Mn x O 3 /Super P electrodes and non-aqueous electrolytes were also fabricated and measured in this work. The oxygen reduction reaction (ORR) and oxy...
