Loosening the Solvation Cage in Polysaccharide Polymer Electrolyte for Sustainable Lithium Metal Batteries

Biomass with naturally ion-conducting segments (e.g., hydroxyl) holds promise for sustainable batteries. Several expeditions are proposed to successfully enhance the ion conduction in biomass polymer mainly by intermolecular structure regulation. Presently, the recognition and research of biomass polymer electrolytes are still limited, requiring continuous explorations to promote the application of such promising electrolytes. Herein, a molecularly asymmetric electrolyte is produced, comprising polysaccharides of starch and chitosan. The strong Li
