  "textContent": "A battery cell including an electrode assembly present in a battery casing. The electrode assembly includes a positive electrode, a negative electrode and a separator interposed between the positive electrode and the negative electrode. The separator includes a porous polymer substrate, a first organic/inorganic porous coating layer on at least one surface of the porous polymer substrate, and a second organic/inorganic porous coating layer on a surface of the first organic/inorganic porous coating layer. The first organic/inorganic porous coating layer includes first inorganic particles and a first binder polymer, the second organic/inorganic porous coating layer includes second inorganic particles and a second binder polymer, the second organic/inorganic porous coating layer faces the positive electrode, and the second binder polymer has a weight average molecular weight higher than the weight average molecular weight of the first binder polymer.",
