Metal‐organic frameworks (MOFs) are excellent precursors for electrode materials preparations. Synergistic effects may exist between different metal centers in multivariate MOFs, making them often more effective than single‐metal MOFs. Herein, we propose an atom economic mechanochemical method to realize the efficient component regulation of target multivariate MOFs. Moreover, by combining the synthesis of multivariate MOFs and exfoliating MXene, multivariate MOF/MXene composites can be obtained via a one‐step strategy. A further selenization process can derive them into selenides@C/MXene composites. These derived composites contain multiple nanostructured metal selenides embedded in multi‐heteroatom doped carbon matrix. For these composites, abundant heterojunction structures are formed, which can build internal self‐built electric field and effectively enhance the reaction kinetics for sodium‐ion storage. More importantly, the electrochemical performance of NCMS@C/MX composites can be optimized due to the intrinsic characteristics of the containing metal selenides. Overall, experimental results demonstrate the universality of this solvent‐free synthesis route for controllable preparation of high‐performance selenides@C/MXene electrode materials. It provides a feasible and environmentally friendly method to adjust metal ratios for optimal energy storage performance. We hope this research inspires optimization strategies for high‐performance electrode materials and leads to development of energy storage materials with more rational structures and better performance.
