Abstract

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.
