Abstract

An oxide particle coated with amino groups, which is a composite LLZO particle; the composite LLZO particle includes a first LLZO particle. A hydroxide ion layer is coated on an outer surface of the first LLZO particle. The hydroxide ion layer and the first LLZO particle form a second order LLZO composite particle. A dopamine layer is coated on an outer side of the second order LLZO composite particle. Dopamine molecules of the dopamine layer are hydrophobic to protect the first LLZO particle and to prevent the first LLZO particle from being dampened. A CTAB (cetyltrimethylammonium bromide) layer is coated on an outer side of the dopamine layer. A part of the CTAB molecules is mixed within the dopamine layer and the hydroxide ion layer.
