Abstract

An additive for a positive electrode material includes an internal component and an external component. The internal component contains a silane coupling agent modified inorganic lithium salt. The external component is formed on a surface of the internal component and contains a polymer with a low melting point. The internal component and the external component form a core-shell structure together, and the shell has a porosity of 0.01% to 20%. A positive electrode material and a lithium-ion battery including the additive, and method of preparing the lithium-ion battery are also provided.
