Title:
ELECTRODE MATERIAL AND ELECTRODE MATERIAL MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2023142043
Kind Code:
A
Abstract:
To provide an electrode material with excellent output characteristics while suppressing changes in crystal structure due to moisture, and a simple method for manufacturing the electrode material.SOLUTION: An electrode material includes lithium vanadium phosphate bonded to a conductive carbon material, the lithium vanadium phosphate is a mixture with titanium or a titanium compound such as titanium (IV) oxide. The lithium vanadium phosphate forms a mixture in which particles of a titanium compound such as titanium or titanium (IV) oxide are mixed inside and on the surface of a crystal whose base material is lithium vanadium phosphate. This electrode material is manufactured through a crystallization step that combines a conductive carbon material and the lithium vanadium phosphate. The crystallization step includes an addition step of adding titanium (IV) oxide, a mixing step of mixing water as a solvent, and a drying step of spray drying.SELECTED DRAWING: Figure 1
