Abstract
Abstract Polymer electrolytes (PEs) have been deemed as a sought‐after candidate for next‐generation lithium batteries. Substantial effort has been dedicated to exploiting PEs with improved comprehensive performance. Organoboron compounds have aroused great interest in PEs due to their distinct characteristics such as high design diversity, excellent thermal stability, promoting lithium‐ion transportation, and raising Li + transference number. Organoboron compounds also have unique functions that facilitate the development of a stable solid electrolyte interface on the electrode surface. Their diversified structures and multiple functions are fundamentally associated with boron's hybridization form that determines the electronic structure of boron as a central atom. Here, recent advancement in organoboron‐containing PEs is reviewed in the aspect of polymer matrixes with boron moieties and organoboron additives for PEs. This review aims to highlight the diverse roles and high application potentials of organoboron compounds utilized in PEs. It is anticipated to provide a clear perspective of organoboron‐containing PEs and to spur more research interests for the exploration of safe and efficient lithium batteries.
