Thermally Healable Electrolyte‐Electrode Interface for Sustainable Quasi‐Solid Zinc‐ion Batteries

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(9)

Published: Jan. 3, 2024

Quasi-solid zinc-ion batteries using hydrogel electrolytes show great potential in energy storage devices owing to their intrinsic safety, fewer side reactions and wide electrochemical windows. However, the dendrite issues on zinc anodes cannot be fundamentally eliminated anode-electrolyte interfacial interspace is rarely investigated. Here, we design a dynamically healable gelatin-based electrolyte with highly reversible sol-gel transition, which can construct conformal electrode-electrolyte interface further evolve into stable solid-solid by situ solidification. The unique helical gelatin chain structure provides uniform channel for ion transport bridging effect of sulfate groups. As consequence, enables dendrite-free repeatedly repairs interspaces transition retain long-lasting protection sustainable batteries.

Abstract Rechargeable batteries play an integral role toward carbon neutrality. Environmentally sustainable should consider the trade‐offs between material renewability, processability, thermo‐mechanical and electrochemical performance, as well transiency. To address this dilemma, we follow circular economy principles to fabricate fungal chitin nanofibril (ChNF) gel polymer electrolytes (GPEs) for zinc‐ion batteries.
