摘要： A battery has an electrode with a mixture layer including electroactive material formed on a current collector whose exposed part is welded to a lead, and also a separator that shrinks with heat. In the battery, a heat shrinkage-preventing layer is provided on a portion of the separator that faces the lead. As a result, even if a minor short-circuit occurs and a large amount of current is flown to a minor short-circuit region, the heat shrinkage-preventing layer prevents expansion of a short-circuit area resulting from heat shrinkage of the separator. Thus, a conspicuous decrease in battery properties is prevented.
摘要翻译：电池具有具有混合层的电极，包括形成在集电体上的电活性材料，其暴露部分焊接到引线上，以及还具有热收缩的隔板。在电池中，隔板的面向引线的部分设置有防热层。结果，即使发生小的短路并且大量的电流流向短路区域，因此防热层防止由隔板的热收缩引起的短路区域的膨胀。因此，防止了电池特性的显着降低。

摘要： A non-aqueous electrolyte secondary battery including: a positive electrode having a positive electrode material mixture containing a composite lithium oxide; a negative electrode; a polyolefin separator; a non-aqueous electrolyte; and a heat-resistant insulating layer interposed between the positive and negative electrodes. The positive electrode active material mixture has an estimated heat generation rate at 200° C. of not greater than 50 W/kg. The estimated heat generation rate is determined by obtaining a relation between absolute temperature T and heat generation rate V of the positive electrode material mixture using an accelerating rate calorimeter; plotting a relation between the inverse of absolute temperature T and the logarithm of heat generation rate V according to the Arrhenius law; obtaining a straight line fitted to the plotted points in a heat generation temperature range of T

摘要： A non-aqueous electrolyte secondary battery comprises a positive electrode and a negative electrode capable of intercalating and de-intercalating lithium, a non-aqueous electrolyte and separators or solid electrolytes. The negative electrode contains, as a main component, composite particles constructed in such a manner that at least part of the surface of nuclear particles comprising at least one of tin, silicon and zinc as a constituent element, is coated with a solid solution or an inter-metallic compound composed of the element included in the nuclear particles and another predetermined element which is not an element included in the nuclear particles. To improve the ability of the battery, the composite particles mentioned above can include at least one trace element selected from iron, lead and bismuth. The porosity of a mixture layer at the negative electrode is 10% or more and 50% or less. The amount of the non-aqueous electrolyte, the thickness of the separators or the like is restricted in a specific value. The foregoing construction suppresses occurrence of an internal short circuit between the positive electrode and the negative electrode caused by expansion of the negative electrode materials, thereby achieving a high capacity battery with a superior charge/discharge cycle properties, which is suitable for a high-speed charging.
