Abstract:
The all-ceramic RuO2@La0.7Ca0.3CuO3 membrane cathode contributes to an ultra-high capacity of 21 518 mA h g-1 over 110 cycles in Li-O2 batteries. A simple infiltration technique is effective for obtaining a highly active supported RuO2 catalyst, and a solvent with a high donor number should be preferentially chosen because it contributes to a much higher capacity.
