Abstract

Alkali-ion batteries have been widely used nowadays. The development of solid-state electrolytes (SSEs) to replace the widely used organic liquid electrolytes could effectively solve the issue of combustion due to the formation of alkali metal dendrites. However, no SSE has been commercialized, since no one has yet to meet all the criteria from real application until now. Therefore, exploration of new materials for SSEs is highly demanded. Herein, a series of new materials, metalorganic compounds, are developed for superionic conductivity for the first time. Three new crystal structures are solved. Among them, the ligand-coordinated derivates show pronounced ionic conductivities, e.g., the ion conductivity of sodium carbazolide ditetrahydrofuran researches as high as 1.2×10-2S cm-1 at 150 °C, which is among the top Na+ conductors under the same condition. The migration of the Li+/Na+ may be facilitated by the dynamic equilibrium of neutral ligand and the large size of anions. More importantly, these newly developed family of superionic conductor provides vast opportunities for discovering new materials in the future.
