Heterojunction electrode materials derived from MOFs have been shown to effectively improve capacity and rate performance. In this paper, ZnS/Co 9 S 8 (ZCS) heterojunction is successfully embedded in the three-dimensional spatial structure composed of cellulose fiber and MXene, forming a unique composite system by solvothermal method and electrostatic self-loading technology. ZCS particles are well dispersed to the fiber substrate and MXene, exhibited a large specific surface area of 54.80 m 2 g −1 and high level of structural defects, which p...
