Abstract: PURPOSE: A ceramic particle capable of improving charging and discharging characters of a lithium battery including a polymer film, the polymer film including the particle, and a manufacturing method of the ceramic particle are provided to enhance the amount of an impregnated electrolyte and ion conductivity of the polymer film. CONSTITUTION: A ceramic particle has a core and shell structure. The core includes silica, and the shell includes a polyelectrolyte which is chemically bonded to the core. The silica is an organic-inorganic hybrid silica. The polyelectrolyte includes a lithium ion. The chemical bond is a Si-C bond. The polymer film includes ceramic particles. The content of the ceramic particle is 3-30 parts by weight based on 100 parts by weight of the polymer. A manufacturing method of the ceramic particle comprises the following steps: preparing silica particles in which a reactive functional group is connected to the surface; and forming a polymer electrolyte layer on the silica surface by reacting the silica particles with monomers.
