Zinc-air battery is among the most promising technologies for near future batteries due to its large theoretical specific capacity, high energy density, and low manufacturing cost. One of the challenging issues is the sluggish oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) from the air electrode. To address this problem, we focus on the bifunctional electrocatalyst Pt nanoparticles decorated on the surface of electrospun spinel bimetal oxide NiCo₂O₄. The as-prepared catalyst can provide higher catalytic activity and long-term stability than the Pt/C electrocatalyst towards higher performance of Zn-ion batteries.
