Abstract:<\/h4>\n
Oxides with a face-centred cubic (fcc) anion sublattice are generally not considered as solid-state electrolytes as the structural framework is thought to be unfavourable for lithium (Li) superionic conduction. Here we demonstrate Li superionic conductivity in fcc-type oxides in which face-sharing Li configurations have been created through cation over-stoichiometry in rocksalt-type lattices via excess Li. We find that the face-sharing Li configurations create a novel spinel with unconventional stoichiometry and raise the energy of Li, thereby promoting fast Li-ion conduction. The over-stoichiometric Li-In-Sn-O compound exhibits a total Li superionic conductivity of 3.38 \u00d7 10-4<\/sup> S cm-1<\/sup> at room temperature with a low migration barrier of 255 meV. Our work unlocks the potential of designing Li superionic conductors in a prototypical structural framework with vast chemical flexibility, providing fertile ground for discovering new solid-state electrolytes.<\/p>\n","protected":false},"excerpt":{"rendered":"DOI: 10.1038\/s41563-024-01800-8 Authors: Yu Chen, Zhengyan Lun, Xinye Zhao, Krishna Prasad Koirala, Linze Li, Yingzhi Sun, Christopher A.
