METHOD FOR MANUFACTURING OXIDE PARTICLES COATED WITH AMINO GROUPS

includes the steps of: placing a plurality of first LLZO particles and a methanol into a wet mixer for mixing to form a first mixed slurry; then placing a tris (tris(hydroxymethyl)aminomethane) material and a tris(hydroxymethyl)aminomethane hydrochloride into the wet mixer for grinding and stirring to form a second mixed slurry and to cause that an outer surface of each of the first LLZO particles is coated with a hydroxide ion layer; then placing a dopamine hydrochloride into the wet mixer for mixing to form a third mixed slurry and to cause that a dopamine layer is coated on an outer surface of the hydroxide ion layer on each of the first LLZO particles. A CTAB (cetyltrimethylammonium bromide) surfactant is added into the third mixed slurry.
