To improve Li storage capacity and the structural stability of Ti 3 C 2  MXene-based electrode materials for lithium-ion batteries (LIBs), a facile strategy is developed to construct three-dimensional (3D) hierarchical porous Ti 3 C 2 /bimetal-organic framework (NiCo-MOF) nanoarchitectures as anodes for high-performance LIBs. 2D Ti 3 C 2  nanosheets are coupled with NiCo-MOF nanoflakes induced by hydrogen bonds to form 3D Ti 3 C 2 /NiCo-MOF composite films through vacuum-assisted filtration technology. The morphology and electrochemical properties of Ti 3 C 2 /NiCo-MOF are influenced by the mass ratio of MOF to Ti 3 C 2 . Owing to the interconnected porous structures with a high specific surface area, rapid charge transfer process, and Li +  diffusion rate, the Ti 3 C 2 /NiCo-MOF-0.4 electrode delivers a high reversible capacity of 402 mAh g −1  at 0.1 A g −1  after 300 cycles; excellent rate performance (256 mAh g −1  at 1 A g −1 ); and long-term stability with a capacity retention of 85.7% even after 400 cycles at a high current density, much higher than pristine Ti 3 C 2  MXene. The results highlight that Ti 3 C 2 /NiCo-MOF have great potential in the development of high-performance energy storage devices.
