Polymeric Electrolytes for Ambient Temperature Lithium Batteries

Interfacial engineering of solid electrolytes

The roles of interfaces in either blocking or enhancing ionic conduction in various types of solid electrolytes, including lithium, sodium, oxygen and other types of ion conductors as well as proton conductors, are critically reviewed. Two important fundamental interfacial phenomena, namely the formation of space charges and two-dimensional interfacial phases (complexions), can markedly alter i...

Materials design of solid electrolytes.

S olid electrolytes play an important role in several technological applications, such as fuel cells. Optimization of such materials is often done by trial and error. The work of Andersson et al. (1) in this issue of PNAS demonstrates that the choice of dopants can be guided by computer simulations, in which parameters that are essential for the high ionic conductivity are determined from a ser...

Solid lithium electrolytes based on an organic molecular porous solid.

A new type of solid lithium-ion conducting electrolytes prepared by incorporation of Li(+) ions into a cucurbit[6]uril (CB[6])-based organic molecular porous solid shows high Li(+) ion conductivity (∼10(-4) S cm(-1)) and mobility (transference numbers, tLi(+) = 0.7-0.8). In addition, the solid electrolytes show excellent, thermally stable performance even after several temperature cycles.

Resistance-change devices based on solid electrolytes

Scalable elements that can be switched between widely-separated non-volatile resistance states at very low power are desirable for applications in next generation memory and logic. One potential approach involves the use of solid electrolyte films. A mobile metal ion-containing electrolyte film sandwiched between an oxidizable metal layer and an inert electrode constitutes a device which revers...
