Regulating Interfacial Wettability for Fast Mass Transfer in Rechargeable Metal-Based Batteries

Abstract

The interfacial wettability between electrodes and electrolytes could ensure sufficient physical contact and fast mass transfer at the gas–solid–liquid, solid–liquid, and solid–solid interfaces, which could improve the reaction kinetics and cycle stability of rechargeable metal-based batteries (RMBs). Herein, interfacial wettability engineering at multiphase interfaces is summarized from the electrolyte and electrode aspects to promote the interface reaction rate and durability of RMBs, which illustrates the revolution that is taking place in this field and thus provides inspiration for future developments in RMBs. Specifically, this review presents the principle of interfacial wettability at macro- and microscale and summarizes emerging applications concerning the interfacial wettability effect on mass transfer in RMBs. Moreover, deep insight into the future development of interfacial wettability is provided in the outlook. Therefore, this review not only provides insights into interfacial wettability engineering but also offers strategic guidance for wettability modification and optimization toward stable electrode–electrolyte interfaces for fast mass transfer in RMBs.
