Abstract
Disclosed are a lithium salt expressed by a formula, LiAlXn(OY)4-n, where “X” is an electrophilic substituent group and “Y” is an oligoether group, an ionic conductor with the lithium salt dispersed in a structural member, and a liquid electrolyte with the lithium salt dissolved in a solvent. For example, the ionic conductor exhibits high ionic conductivity as well as high lithium ion transport number.
