ABSTRACT Aluminum‐ion batteries (AIBs) hold great promise for large‐scale energy storage owing to their cost‐effectiveness. However, Al‐metal anodes face challenges such as passivation, dendrites, and structural degradation, thus limiting long‐term cycling stability. Inspired by the highly sensitive diffuse nerve net of sea anemone tentacles, a bioinspired Al@CNT anode is rationally designed by incorporating aluminophilic carbon nanotubes (CNTs) into Al matrix. These CNTs form a homogeneous neur
