Advanced Energy Materials, EarlyView.To overcome silicon anode instability, a hierarchical silicon/carbon composite fabricated from industrial waste via a scalable milling process is demonstrated. In‐depth post‐mortem analysis reveals how functional carbons—a CNT network and graphene shell—synergistically suppress degradation. This robust design delivers outstanding stability in practical
