A novel Bi-based anode material with a stable alloy reaction is prepared by a solvothermal method. The Mg storage mechanism is elucidated for the first time. Owing to the space confinement of in situ conversion, the anode material shows superior magnesium storage performance, especially the cycling stability (capacity retention >96% after 100 cycles).
