LITHIUM VANADIUM OXIDE CRYSTAL, ELECTRODE MATERIAL, AND POWER STORAGE DEVICE, AND METHOD FOR MANUFACTURING LITHIUM VANADIUM OXIDE CRYSTAL
Document Type and Number:
WIPO Patent Application WO/2021/075168
Kind Code:
A1
Abstract:
Provided are a lithium vanadium oxide crystal whereby improved electrochemical characteristics can be achieved, and an application for the same. This novel lithium vanadium oxide crystal is represented by the chemical formula Li3+xV1-xMxO4, in which Li3VO4 is doped with a quadrivalent metal species M, the Li3VO4 has a single-crystal structure in only a γ phase in a temperature environment that includes normal temperature, and the quadrivalent metal species M is included in a ratio such that x ≥ 0.2.
