PURPOSE: An electrode assembly is provided to improve battery capacity by increasing ion conductivity by using barium titanate(BaTiO3) as a ceramic material. CONSTITUTION: An electrode assembly includes a positive electrode, a negative electrode, and a separator. The positive electrode includes a positive electrode active material layer. The negative electrode includes a negative electrode active material layer. The separator separates the positive electrode and negative electrode and comprises a porous membrane bonded by a first ceramic material, a second ceramic material, and a binder. The first ceramic material is barium titanate(BaTiO3). The second ceramic material is at least one material selected from the group consisting of silica(SiO2), alumina(Al2O3), zirconium oxide(ZrO2) and titanium oxide(TiO2). |
