摘要： This separator is provided at least at one surface thereof with a heat-resistant layer containing inorganic oxide particles and a binder, and the inorganic oxide particles have a component containing gallium in the range of 5 to 200 weight ppm in an aluminum oxide. This lithium ion secondary battery has: an electrode body including a positive electrode plate and a negative electrode plate laminated by interposing the separator therebetween; and a non-aqueous electrolytic solution impregnated in the electrode body. A lithium ion secondary battery using the separator having the heat-resistant layer is therefore less likely to cause a rise in resistance even in use under high-rate conditions.

摘要： An oxygen permeable film including an aggregate of water-repellent particles and having an average particle size of the particles of 0.01 to 50 μm has a contact angle with water of not less than 120° and super water repellency, and therefore has an excellent water vapor permeation inhibiting capability. As the particles, fluorocarbon resins such as polytetrafluoroethylene, polyvinyl fluoride and polyvinylidene fluoride are suitable. The specific surface area of the oxygen permeable film is preferably not less than 0.1 m2/g and not more than 500 m2/g.

摘要： In an AA alkaline battery, an opening of a battery case is sealed by a gasket. The battery case houses a positive electrode, a negative electrode, a separator, and an alkaline electrolyte. The positive electrode contains manganese dioxide having a potential of higher than or equal to 270 mV measured by using mercurous oxide (Hg/HgO) as a reference electrode in 40 wt % of a potassium hydroxide aqueous solution. The negative electrode contains 4.0 g or more of zinc. The gasket has a hydrogen gas permeability coefficient, per one gasket, in the range from 6×10−10 (cm3H2(STP)/sec·cmHg) to 3×10−9 (cm3H2(STP)/sec·cmHg), both inclusive.
