The Cover Feature illustrates the lithium storage mechanism of binary metal oxide Bi 2 Mo 3 O 12 as high‐capacity anode material. The “parent” Bi 2 Mo 3 O 12 undergoes a typical conversion reaction into metallic Bi and Li 2 MoO 4 components (represented by the children) during initial lithiation process, followed by reversible lithium storage through alloying/de‐alloying of Li 3 Bi and intercalating/de‐intercalating of Li 2+ x MoO 4 for eventual capacity contribution. Compositing Bi 2 Mo 3 O 12 with Ti 3 C 2 ‐based MXene significantly improves cycle stability and rate capability of the Bi 2 Mo 3 O 12 /Ti 3 C 2 anode material.
