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...
متن کاملInterfacial 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...
متن کاملThe Electrochemical Influence and Oxycen Exchange Properties of Mixed Conducting Electrode Materials on Solid Oxide Electrolytes
Solid electrolytes based on oxygen ion conductors find extensive applications as devices for oxygen sensor, oxygen pumps, solid oxide fuel cells and electrocatalytic reactors. When using ceramic ionic conductors for applications, frequent attempts are made to improve the performance of the electrochemical system by apply'rig mixed conductors as thin top layers instead of the conventional ir~ert...
متن کاملCharacterization of Lithium-based Solid Polymer Electrolytes
Sol-gel derived poly(oxyethylene)/siloxane hybrids doped with lithium hexafluoroantimonate, LiSbF6, have been prepared. Compositions of these novel xerogel electrolytes were identified using the conventional d-U(2000)nLiSbF6 notation, (where n is the molar ratio of oxyethylene moieties per Li + ion) and samples with n between ∞ and 2.5 were characterized by conductivity measurements, cyclic vol...
متن کاملSolid 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.
