Replacing liquid electrolytes with solid‐state polymer electrolytes (SPEs) can solve the safety hazards of Li metal batteries (LMBs) while increasing their energy density. However, there has been limited success so far in preparing advanced SPEs with controllable molecular structure and chemical composition, posing great obstacles to further promoting its application in LMBs. Recently, ring‐opening polymerization (ROP), including cationic ROP, anionic ROP, and ring‐opening metathesis polymerization, has become a dazzling new star in achieving SPEs due to its mild polymerization conditions and controllable chemical composition (molecular structure, functional group), etc. Besides, there is no small molecule released during the polymerization process, which means reduced interfacial side reaction. Hence, in this review, the merits of ROP in preparing SPEs and its mechanism as well as interfering factors, etc are evaluated from the perspective of synthetic chemistry. Furthermore, the review focuses on outlining the existing cases related to ROP as much as possible and summarize them from different ring structures (from triple ring to multivariate ring) and polymerization methods, hoping to provide a comprehensive understanding and serve as strategic guidance for designing high‐performance SPEs. Challenges and opportunities regarding this burgeoning field are also discussed at the end.

“…Among the various forms of BCP, cylindrical (C) pore channels have been applied, though the lamellar (L) structures possess higher f values and theoretically higher ionic conductivity than C, but L has been explored very little. Liu et al [ 233 ] employed an intermediate layer of azobenzene to synthesize a series of tablet-b-bottlebrush (TB) BCP electrolytes ( Figure 12 c). The liquid crystal polymer segments can form nanopores in a directional and rapid manner after solvent thermal annealing and the presence of polyethylene oxide (PEO) side chains leads to increasing electrical conductivity.…”

With the speedy progress in the research of nanomaterials, self-assembly technology has captured the high-profile interest of researchers because of its simplicity and ease of spontaneous formation of a stable ordered aggregation system. The self-assembly of block copolymers can be precisely regulated at the nanoscale to overcome the physical limits of conventional processing techniques. This bottom-up assembly strategy is simple, easy to control, and associated with high density and high order, which is of great significance for mass transportation through membrane materials. In this review, to investigate the regulation of block copolymer self-assembly structures, we systematically explored the factors that affect the self-assembly nanostructure. After discussing the formation of nanostructures of diverse block copolymers, this review highlights block copolymer-based mass transport membranes, which play the role of “energy enhancers” in concentration cells, fuel cells, and rechargeable batteries. We firmly believe that the introduction of block copolymers can facilitate the novel energy conversion to an entirely new plateau, and the research can inform a new generation of block copolymers for more promotion and improvement in new energy applications.

Self-healing polymer electrolytes are essential for overcoming the limitations of liquid and solid electrolytes by offering superior mechanical robustness, enhanced safety, and repeated processability. Herein, we present thermally reprocessable and self-healing thermosets for solid polymer electrolytes using sulfonylimide-based anionic monomers and thermo-reversible Diels−Alder chemistry. Six different types of linear copolymers are synthesized by varying the chemical structures of furancontaining monomers and the proportion of electrolytic components. Then, bismaleimide cross-linkers are introduced to form thermally reversible cross-linked networks. We investigate the effect of the comonomer ratio and monomer structure on the thermomechanical and electrochemical properties of these polymers. Furthermore, we evaluate the mechanical and ion conducting properties after up to 30 thermal reprocessing cycles. Our findings demonstrate the potential of these thermosets as promising candidates for high-performance solid polymer electrolytes in lithium-ion batteries.
