Abstract: The sluggish kinetics and large overpotential of oxygen reduction reaction (ORR) severely limit the widespread production and application of metal-air batteries. Herein, a conductive 3D porous spiral-like polyhedron structures composed of nitrogen-doped carbon nanosheets (L/D-SPNC),… read more here.
