摘要： Disclosed is a positive electrode for non-aqueous electrolyte secondary batteries, the positive electrode including a positive electrode material mixture layer which includes positive electrode active material particles and a binder. A curve representing a correlation between a distance from a current collector in the thickness direction of the positive electrode material mixture layer and an amount of the binder has a first maximum point, a minimum point, and a second maximum point. The minimum point corresponds to a position in a center area of the positive electrode material mixture layer in a thickness direction thereof, and the first and second maximum points correspond to a position nearer the current collector and a position further away from the current collector than the position corresponding to the minimum point, respectively. A ratio W1/W2 of an amount W1 at the first maximum point to an amount W2 at the minimum point of the binder per 100 parts by weight of the positive electrode active material particles is greater than 2.

摘要： A lithium secondary battery that is excellent in resistance to short-circuits and heat, is unlikely to suffer a capacity loss due to impact such as dropping, and has a high capacity. The lithium secondary battery includes an electrode assembly including a strip-like positive electrode and a strip-like negative electrode that are wound together with a porous heat-resistant layer interposed therebetween, a non-aqueous electrolyte, and a battery can. The battery has a restricting part for restricting vertical movement of the electrode assembly. The distance A from the restricting part to the inner bottom face of the battery can and the width B of the negative electrode satisfy the relation: 0.965≦B/A≦0.995.

摘要： A method for evaluating the safety of a battery under an internal short-circuit condition. The method for evaluating an internal short-circuit of a battery is characterized in that a short-circuit can be caused at a desired location inside the battery. According to the evaluation method of the invention, the evaluation result is not affected by the constitution of the outermost part of the battery unlike nail penetration tests which are conventional evaluation methods. Also, unlike crush tests which are conventional evaluation methods, the locations of short-circuits do not vary among tests and the safety under an internal short-circuit condition can be evaluated accurately.
