The Cover Feature illustrates the lithium storage mechanism of binary metal oxide Bi₂Mo₃O₁₂ as high‐capacity anode material. The “parent” Bi₂Mo₃O₁₂ undergoes a typical conversion reaction into metallic Bi and Li₂MoO₄ components (represented by the children) during initial lithiation process, followed by reversible lithium storage through alloying/de‐alloying of Li₃Bi and intercalating/de‐intercalating of Li_2+xMoO₄ for eventual capacity contribution. Compositing Bi₂Mo₃O₁₂ with Ti₃C₂‐based MXene significantly improves cycle stability and rate capability of the Bi₂Mo₃O₁₂/Ti₃C₂ anode material.
