Abstract

Bulk-type all-solid-state Li batteries (ASLBs) employing inorganic solid electrolytes are considered a next-generation energy storage system due to their potentials to overcome the limitations of current lithium-ion batteries (LIBs) such as a safety concern and narrow operating temperature. Inorganic solid electrolytes (SEs) with high ionic conductivity, good chemical- and electrochemical stability are crucial for high-performance ASLBs. Among them, halide SEs have gained attention for their high-voltage stability, high ionic conductivity, and potentially lower cost compared to sulfide counterparts. Notably, the recently reported LiNbOCl4 exhibiting high ionic conductivity (≥ 10 mS cm−1) can be a promising candidate. However, in the literature, LiNbOCl4 was prepared by the reaction of LiOH and NbCl5, producing caustic HCl as a by-product. This is problematic for large-scale production and may hinder potential improvement through compositional modification. In this work, we demonstrate an alternative hydrochloric acid-free synthesis route using NbOCl3 that can yield LiNbOCl4 with the same crystal structure and high ionic conductivity of 8.4 mS cm−1 at 25 °C. To confirm its feasibility for the bulk-type ASLB application, its electrochemical properties and dry room stability were also investigated.

期刊介绍: This interdisciplinary journal is devoted to the physics, chemistry and materials science of diffusion, mass transport, and reactivity of solids. The major part of each issue is devoted to articles on: (i) physics and chemistry of defects in solids; (ii) reactions in and on solids, e.g. intercalation, corrosion, oxidation, sintering; (iii) ion transport measurements, mechanisms and theory; (iv) solid state electrochemistry; (v) ionically-electronically mixed conducting solids. Related technological applications are also included, provided their characteristics are interpreted in terms of the basic solid state properties. Review papers and relevant symposium proceedings are welcome.
