Enhanced Ionic Motion in Solid Electrode Materials

  • W. Weppner
Part of the NATO Conference Series book series (NATOCS, volume 2)


High power density batteries require rapid equilibration of compositional inhomogeneities within the mixed ionic-electronic conducting electrodes. Large enhancement of the ionic motion may be observed for semi-conducting materials with a small number of highly mobile electronic species. Metallic conduction is a disadvantage. In order to meet the various conflicting requirements, the coulometric titration curve should show large slopes at completely charged and discharged states.
