Informed by theoretical guidance on solvation process, dimethyl(3,3-difluoro-2-oxoheptyl)phosphonate with high permanent dipole moments effectively substitute the coordination of H₂O with charge carriers through relatively strong ion-dipolar interactions, forming a water-lean environment of solvated Zn²⁺ and improved interfacial characteristics of electrodes, thus improving the Zn plating/stripping reversibility.

利用离子-偶极相互作用进行水稀释溶剂化化学：在水性锌离子电池中实现高稳定性锌阳极

在溶剂化过程的理论指导下，具有高永久偶极矩的二甲基（3,3-二氟-2-氧代庚基）膦酸盐通过相对较强的离子-偶极相互作用有效地取代了 H₂O 与电荷载流子的配位，形成了溶剂化 Zn²⁺ 的贫水环境并改善了电极的界面特性，从而提高了 Zn 镀锌/剥离可逆性。
