A strained 1-phenyl-2,3-dimethylphosphirene undergoes anionic ring-opening polymerization upon initiation with n-butyl lithium at ambient temperature to yield polyvinylenephosphine, an unsaturated organophosphorus polymer.

In this paper we report the performances of a lithium-ion sulfur battery characterized by a polymer configuration. The cell, based on a sulfur-carbon cathode, a Li-Sn-C nanostructured anode and a PEO-based, polysulfide-added electrolyte, shows very good electrochemical performances in terms of stability and delivered capacity. The remarkable cell performances are ascribed to the mitigation of t...

Is it possible to exceed the lithium redox potential in electrochemical systems? It seems impossible to exceed the lithium potential because the redox potential of the elemental lithium is the lowest among all the elements, which contributes to the high voltage characteristics of the widely used lithium ion battery. However, it should be possible when we use a molecule-based ion which is not re...

This paper reviews different modification methods to cathode, anode and electrolyte materials in view of their electrochemical properties for application in lithium/sulfur batteries. In the sulfur electrode, carbonaceous materials, conductive polymer materials, and metal oxide adsorbing materials are employed to enhance conductivity and reduce polysulfide dissolution. The effects of anodes and ...

A family of lithium-ion-conducting composite polymer-glass electrolytes containing the glass composition 14Li2O–9Al2O3–38TiO2– 39P2O5 (abbreviated as (LiAlTiP)xOy) with high ionic conductivity, an excellent electrochemical stability range, and high compatibility with lithium insertion anodes is described. An optimized composition has a room temperature conductivity of 1:7 10 4 S cm , an Liþ tra...

Due to its high theoretical energy density (2600 Wh kg-1), low cost, and environmental benignity, the lithium-sulfur (Li-S) battery is attracting strong interest among the various electrochemical energy storage systems. However, its practical application is seriously hampered by the so-called shuttle effect of the highly soluble polysulfides. Herein, a novel design of multifunctional sandwich-s...

High ionic conductivity solid polymer electrolyte (SPE) has long been desired for the next generation high energy and safe rechargeable lithium batteries. Among all of the SPEs, composite polymer electrolyte (CPE) with ceramic fillers has garnered great interest due to the enhancement of ionic conductivity. However, the high degree of polymer crystallinity, agglomeration of ceramic fillers, and...

In this study, we prepared high-stability hematite mesocrystals by a facile route without polymer additives. In particular, the rhombic hematite mesocrystals exhibit excellent lithium insertion behavior compared to the hematite single-crystals.

A BIPV-powered smart window comprising a building-integrated photovoltaic (BIPV) panel and an all-solid-state electrochromic (EC) stack is proposed. In the proposed device, the output voltage of the BIPV panel varies in accordance with the intensity of the incident light and is modulated in such a way as to generate the EC stack voltage required to maintain the indoor illuminance within a speci...

I review some considerations that suggest that the biochemical products of evolution may provide hints concerning the way forward for the development of better electrolytes for lithium polymer batteries.
