Abstract
Abstract Side reactions on zinc metal (Zn) anodes are formidable issues that cause limited battery life of aqueous zinc‐ion batteries (AZIBs). Here, a facile and controllable layer‐by‐layer (LbL) self‐assembly technique is deployed to construct an ion‐conductive and mechanically robust electrolyte/anode interface for stabilizing the Zn anode. The LbL film consists of two natural and biodegradable bio‐macromolecules, chitosan (CS) and sodium alginate (SA). It is shown that such an LbL film tailors the solvation sheath of Zn ions and facilitates the oriented deposition of Zn. Symmetric cells with the four double layers of CS/SA ((CS/SA) 4 –Zn) exhibit stable cycles for over 6500 h. The (CS/SA) 4 –Zn||H 2 V 3 O 8…
