Abstract

La presente invención proporciona una celda de batería en la que un conjunto de electrodos, que comprende: un electrodo positivo; un electrodo negativo; y un separador interpuesto entre el electrodo positivo y el negativo, está integrado en una carcasa de batería, donde el separador incluye: un sustrato de polímero poroso; una primera capa de recubrimiento poroso orgánico-inorgánico formada en al menos una superficie del sustrato de polímero poroso; y una segunda capa de recubrimiento poroso orgánico-inorgánico formada sobre la primera capa de recubrimiento poroso orgánico-inorgánico. La primera capa de recubrimiento poroso orgánico-inorgánico incluye una primera partícula inorgánica y un primer polímero aglutinante, la segunda capa de recubrimiento poroso orgánico-inorgánico incluye una segunda partícula inorgánica y un segundo polímero aglutinante, la segunda capa de recubrimiento poroso orgánico-inorgánico está orientada hacia el electrodo positivo, y el peso molecular promedio en peso del segundo polímero aglutinante es mayor que el peso molecular promedio en peso del primer polímero aglutinante. En consecuencia, al aumentar la fuerza de adhesión entre el electrodo positivo y el separador, es posible aumentar la seguridad contra sobrecarga sin necesidad de un dispositivo adicional.
