An ode to anodes: Si–Fe–Al composite materials are synthesized by high‐energy ball‐milling as anodes for lithium‐ion batteries. The as‐prepared Si composite anodes deliver high capacity values, high Coulombic efficiencies, and good cycle performance. The performance is mainly attributed to the unique structure of elemental Si uniformly distributed amongst inactive intermetallic phases.
