Controlled/living
radical polymerization was developed to synthesize
branched polyacrylates and polystyrene with tunable degrees of branching
and low dispersities. This method is based on a polymerization-induced
branching process that occurs when n-butyl α-bromoacrylate
is copolymerized under atom transfer radical polymerization conditions.
This novel branching polymerization demonstrates excellent synthetic
versatility, enabling the preparation of complex macromolecular architectures
constructed from branched-polymer building blocks.
Solid-state batteries have become a frontrunner in humankind’s pursuit of safe and stable energy storage systems with high energy and power density. Electrolyte materials, currently, seem to be the Achilles’ heel of solid-state batteries due to the slow kinetics and poor interfacial wetting. Combining the merits of solid inorganic electrolytes (SIEs) and solid polymer electrolytes (SPEs), inorganic/polymer hybrid electrolytes (IPHEs) integrate improved ionic conductivity, great interfacial compatibility, wide electrochemical stability window, and high mechanical toughness and flexibility in one material, having become a sought-after pathway to high-performance all-solid-state lithium batteries. Herein, we present a comprehensive overview of recent progress in IPHEs, including the awareness of ion migration fundamentals, advanced architectural design for better electrochemical performance, and a perspective on unconquered challenges and potential research directions. This review is expected to provide a guidance for designing IPHEs for next-generation lithium batteries, with special emphasis on developing high-voltage-tolerance polymer electrolytes to enable higher energy density and three-dimensional (3D) continuous ion transport highways to achieve faster charging and discharging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
