酰胺与咪唑鎓聚合物保护层实现部分去溶剂化Zn2+传输，锌离子电池循环达2200 h
Coordination Bridges in Confined‐Water Domains Enable Partially Desolvated Zn 2 + Transport in Aqueous Zinc‐Ion Batteries
AI 导读
研究设计了一种含酰胺与咪唑鎓基团的多功能聚合物保护层，用于水系锌离子电池。亲锌酰胺基团提供稳定的Zn2+结合位点，吸湿性咪唑鎓基团构建受限水域并调节局部溶剂化，水分子在离子迁移中充当配位桥但向电极表面的移动受限。
推荐理由
作者把酰胺与咪唑鎓基团引入聚合物保护层，用受限水域同时调节Zn2+溶剂化与界面迁移，为水系锌离子电池的界面设计提供了一条可迁移思路。
创新点
将亲锌酰胺位点与吸湿性咪唑鎓基团集成到同一聚合物保护层中，用受限水域让水分子充当Zn2+迁移的配位桥同时限制其向电极表面扩散，从而在同一界面层上兼顾离子传输与抑制析氢。
