增强型自适应水凝胶电解质构筑高性能锌空气电池
High performance zinc air battery based on enhanced adaptive hydrogel electrolyte
摘要
Abstract
Solid-state zinc-air batteries(ZABs)exhibit great potential for applications in flexible en-ergy storage systems.In this study,an enhanced adaptive neutral hydrogel electrolyte was fabricated by incorporating sodium hyaluronate(SA),polyvinyl alcohol(PVA)and zinc salts using freeze-thaw cycling method.The physicochemical properties and electrochemical performance of the resulting material were systematically analyzed.The results demonstrate that the strong hydrogen bonding be-tween SA and water molecules endows the material with excellent adaptive mechanical properties,water retention capability,and thermal stability.Additionally,the formation of hydrogen bonds effec-tively reduces water activity,thereby inhibiting hydrogen evolution side reactions and zinc dendrite growth.Moreover,the strong binding energy between SA and Zn2+significantly alters the Zn2+trans-port pathway.Benefiting from this optimized design,the symmetric battery exhibits stable cycling for over 5 000 hours at current density of 0.4 mA/cm2.Furthermore,the cycling lifespan and full dis-charge capacity of the ZABs are significantly improved.关键词
