Title:
METHOD FOR PRODUCING LITHIUM-VANADIUM OXIDE CRYSTALS, LITHIUM-VANADIUM OXIDE CRYSTALS, ELECTRODE MATERIAL, AND POWER STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/075627
Kind Code:
A1
Abstract:
Provided are: a method for producing lithium-vanadium oxide crystals that can save energy and have favorable rate characteristics; lithium-vanadium oxide crystals having favorable rate characteristics; an electrode material; and a power storage device. The method comprises: a step for preparing water or a water-containing mixed solution; a step for preparing an aqueous solution the pH of which is adjusted to at least 5 by dissolving a vanadium source and a lithium source in the water or water-containing mixed solution; and a drying step for vaporizing a liquid from the aqueous solution to precipitate lithium-vanadium oxide crystals. The precipitated crystals include primary particles having a diameter of at most 50 nm and pores having a peak at 10 nm or less in the pore distribution.
