Co3O4 nanoparticle modified N, P co-doped carbon paper as sodium carrier to construct stable anodes for Na-metal batteries

Abstract

N, P co-doped carbon paper modified with Co3O4 nanoparticles has excellent sodiophilicity as anode current collector of Na–CO2 batteries, which can stably operate for 165 cycles at current densities of 500 mA g−1 with capacity of 500 mA h g−1.
