Abstract

Abstract : The Cover Feature illustrates the enhanced mobility of ionic charge carriers after substitution of F − on the O 2− site. Interestingly, weakened chemical bonds were observed between the cations (A or B site) and the oxygen ions by the anion doping strategy resulting in an improved oxygen mobility in the lattice. This finding suggests that targeted anion doping is a promising strategy for the development of a new generation of electrolyte materials. More information can be found in the Aricle by J. Gao et al .
