Figure 1

Schematic illustration of the NKO and conventional metal-O2 battery. (a) NKO battery consisted of a Na anode, glassy fiber separator impregnated with 1.0 M of KOTF in G2, and a porous SP cathode. (b) Conventional metal-O2 battery adopting an electrolyte containing the same element M+ as the anode (M = Na/K).
