具有高锂离子电导率的硫化物基固态电解质被认为是最有希望实现实用全固态电池的电解质体系。然而，硫化物基全固态电池的实际应用受到严重的界面问题以及大规模材料制备和电池制造问题的阻碍。与当前电池制造兼容的能够改善电极/电解质界面接触并实现硫化物电解质的大规模生产和基于硫化物的电池组件的可规模制造的涉及液体的界面处理和制备工艺引起了相当大的关注。从这一角度出发，综述了目前硫化物基全固态电池中液体参与处理和工艺的研究进展。然后介绍了相关的化学机理和存在的挑战。最后，还提出了硫化物基电池的未来指导。我们以硫化物基全固态电池为重点，旨在提供对液体参与过程的新见解，并促进具有更高能量密度和更好安全性的全固态电池的发展。
Sulfide-based solid-state electrolytes with ultrahigh lithium ion conductivities have been considered as the most promising electrolyte system to enable practical all-solid-state batteries. However, the practical applications of the sulfide-based all-solid-state batteries are hindered by severe interfacial issues as well as large-scale material preparation and battery fabrication problems. Liquid-involved interfacial treatments and preparation processes compatible with current battery manufacturing capable of improving electrode/electrolyte interface contacts and realizing the mass production of sulfide electrolytes and the scalable fabrication of sulfide-based battery component have attracted considerable attention. In this perspective, the current advances in liquid-involved treatments and processes in sulfide-based all-solid-state batteries are summarized. Then relative chemical mechanisms and existing challenges are included. Finally, future guidance is also proposed for sulfide-based batteries. Focusing on the sulfide-based all-solid-state batteries, we aim at providing a fresh insight on understandings towards liquid-involved processes and promoting the development of all-solid-state batteries with higher energy density and better safety.
