The Co₂P nanoparticles hybridized with unique N-doping carbon matrices have been successfully designed employing ZIF-67 as the precursor via a facile two-step procedure. The Co₂P nanostructures are shielded with reduced graphene oxide (rGO) to enhance electrical conductivity and mitigate volume expansion/shrinkage during sodium storage. As anode materials for sodium-ion batteries (SIBs), the novel architectures of Co₂[email protected]@rGO exhibited excellent sodium storage performance with a high reversible capacity of 225 mA h g^–1 at 50 mA g^–1 after 100 cycles. Our study demonstrates the significant potential of Co₂[email protected]@rGO as anode materials for SIBs.
