  "textContent": "An object of the present invention is to provide a separation membrane for a battery, which is excellent in heat resistance, does not expand and shrink depending on a temperature history, has no problem that, even when pressure is applied at a point due to external pressure, dendrite growth or the like, it is broken at the pressure point and its function is damaged at the broken part, and has no problem that the ionic conductivity decreases to decrease the battery performance, and to provide a battery equipped with such a separation membrane for a battery. A separation membrane for a battery which is constructed by binding a scaly inorganic porous material comprising silica, alumina or the like with a binder in a membrane shape, the separation membrane for a battery being provided on the surface of a positive electrode, a negative electrode or a separator of a battery.",
