The aqueous zinc-ion batteries (AZIB) have emerged as a promising technology in the realm of electrochemical energy storage. Despite its potential advantages terms safety, cost-effectiveness, and inherent AZIB faces significant challenges. Issues attributed to unsupported thermodynamics non-uniform distribution deposition, present formidable obstacles that necessitate resolution. To tackle these challenges, novel strategy adapting hybrid organic-inorganic situ derived solid-to-hydrogel...
