A synergistic CoO/MXene heterostructure anode with facilitated interfacial charge transfer for high-rate micro lithium-ion batteries

, demonstrating remarkable structural integrity and electrochemical reversibility. Furthermore, density functional theory (DFT) calculations analyzed that the MXene-CoO heterostructure enhances conductivity through increased density of states near the Fermi level, optimizes interfacial charge-transfer kinetics to strengthen Li adsorption, and lowers Li⁺ diffusion barriers, collectively contributing to the improved rate performance and cycling stability. This work establishes a novel and controllable strategy for constructing 0D-2D vdW heterostructures and provides mechanistic insights into structure-property relationships, offering a practical pathway toward high-performance anodes for MLIBs applications.
