Since the electrochemical potential of lithium metal was systematically elaborated and measured in early 19th century, lithium-ion batteries with liquid organic electrolyte have been a key energy storage device successfully commercialized at end 20th century. Although battery technology has progressed enormously recent years, it still suffers from two core issues, intrinsic safety hazard low density. Within approaches to address challenges, development all-solid-state (ASSLBs) based on halide solid-state electrolytes (SSEs) displayed for application stationary devices may eventually become an essential component future smart grid. In this Review, we categorize summarize current research status SSEs different halogen anions perspective chemistry, upon which synthetic routes possessing high room-temperature ionic conductivity, compare detail performance terms activation energy, electronic interfacial contact stability, window corresponding optimization strategies each above-mentioned indicators.

Radical polymerization is a powerful technique for producing variety of polymeric materials. However, the chain transfer reaction impedes formation polymers from many common α-olefins such as propene and 1-butene using this method. Consequently, poly(α-olefins) are predominantly produced via coordination polymerization. To address limitation, we have devised strategy involving group radical (GTRP) to facilitate homopolymerization access carbon-chain poly(α-olefins).
