A partially ion-paired solvation structure design is demonstrated that combines the beneficial characteristics of contact-ion pair (CIP) and solvent-separated ion pair (SSIP) structures. A facile desolvation and preferential reduction of anion/fluorinated co-solvent for LiF-dominated interphases are achieved without compromising ionic conductivity, effectively expanding the operational capabilities of lithium batteries under extreme conditions.

极端工作条件下锂硫电池的部分离子对溶剂化结构设计

证明了部分离子对溶剂化结构设计，结合了接触离子对（CIP）和溶剂分离离子对（SSIP）结构的有益特性。在不影响离子电导率的情况下，实现了以LiF为主的界面的阴离子/氟化共溶剂的轻松去溶剂化和优先还原，有效扩展了锂电池在极端条件下的运行能力。
