Abstract Aluminum‐ion batteries (AIBs) attract interest for their promising features of superior safety and long‐life energy storage. Organic materials with engineered active groups are considered promoting storage capabilities. However, the corresponding density (both voltage plateau sufficient sites required) stability still unexpectedly poor.
