CoNiO2/MXene composite is successfully fabricated by a facile hydrothermal method combined with an annealing treatment. The CoNiO2 nanoparticles anchor on MXene evenly form a rough multilayer structure, which can promote Na+ transmission and relieve volume expansion during charge/discharge cycling. The CoNiO2/MXene multilayer structure composite as anode material for sodium-ion batteries delivers a high discharge capacity of 223 mA h g(-1) at 100 mA g(-1) and displays outstanding rate performance of 188 mA h g(-1) at 300 mA g(-1).
