PEO-based electrolytes suffer from huge interfacial resistance, poor Li⁺ transport, and Li dendrite formation in all-solid-state lithium metal batteries (ASSLMBs) operating at around room-temperature. This work proposes the regulation of the Li⁺ solvation environment through halogen-bonding interaction and highlights the importance of “weak solvation” of Li⁺ in solid electrolytes for room temperature ASSLMBs.

弱锂离子溶剂化的超分子聚合物离子导体使室温全固态锂金属电池成为可能

在室温附近运行的全固态锂金属电池（ASSLMB）中，基于 PEO 的电解质存在巨大的界面电阻、较差的 Li ^{+传输以及锂枝晶形成等问题。}这项工作提出通过卤素键相互作用来调节Li ^{+溶剂化环境，并强调了Li}⁺在固体电解质中对于室温ASSLMB的重要性。
