  "textContent": "[Problems] Provided are a battery separator with which a battery with improved safety can be formed, and a battery including the separator. [0002] [Solving Means] The battery separator of the present invention includes a multilayer porous film including at least a resin porous film (I) and a heat-resistant porous layer (II) predominantly composed of heat-resistant fine particles. The battery separator shuts down at a temperature of 100 to 150°C and at a speed of 50 Ω/min·cmor higher. The battery of the present invention includes a positive electrode having an active material capable of intercalating and deintercalating Li ions, a negative electrode having an active material capable of intercalating and deintercalating Li ions, an organic electrolyte and the battery separator of the present invention.",
