We designed an excellent-performance porous nitrogen-doped carbon material with a NiO/Cu/Cu2O hetero-interface derived from bimetal-organic frameworks. The hetero-interfaces between NiO/Cu/Cu2O could boost the Na+ diffusion and increase the electrical conductivity. The obtained composite achieves highly reversible Na-storage with excellent cycling stability and rate capability.
