Rational fabrication of thin-layered NiCo2S4 loaded graphene as bifunctional non-oxide catalyst for rechargeable zinc-air batteries

Zinc-air batteries are the promising electrochemical energy conversion and storage devices due to their high theoretical energy density, environmental benignity, low cost and safety. Developing high-performing bifunctional catalyst to improve the ORR and OER kinetic is the key issue of the researcha...
