Title:
電極活物質被覆用リチウム含有酸化物前駆体溶液とその製造方法
Document Type and Number:
Japanese Patent JP7410226
Kind Code:
B2
Abstract:
To provide a lithium-containing oxide precursor solution for electrode active material coating capable of improving coverage rate of a coating layer when the coating layer is formed by coating and drying on a powder surface of an electrode active material, using a water-based solution as a solvent, and easily handled in atmosphere.SOLUTION: A lithium-containing oxide precursor solution for electrode active material coating contains: Li in amounts of 0.1 to 5.0 mass%; at least one or more elements selected from Nb, F, Fe, P, Ta, V, Ge, B, Al, Ti, Si, W, Zr, Mo, S, Cl, Br,I in amounts of 0.05 to 35 mass%; and water in amounts 60 to 98.4 mass %. The lithium-containing oxide precursor solution for electrode active material coating has an absorbance value of 0.1 or less at a wavelength 660 nm and a surface energy value of 72 mN/m or less.SELECTED DRAWING: Figure 1
