摘要：
A carbon-free and binder-free RuO2/Co3O4 cathode was prepared with porous nanosheet structure on stainless steel felt substrate. Both the porous structure of Co3O4 and the adding of RuO2 improved the catalytic perfor-mance with enhanced discharge capacity (4072 mAh g(-1)) and lower charge voltage (4.05 V) for Li-O-2 batteries.
