    摘要： The present invention provides a sealed nonaqueous electrolyte secondary battery which is equipped with a current interrupt device that is actuated by a rise in internal pressure of a battery case and in which the current interrupt device is actuated in a speedy and stable manner during an overcharge. In the sealed nonaqueous electrolyte secondary battery, an electrode body formed by a positive electrode 10 and a negative electrode that oppose each other via a separator, an electrolyte, and an overcharge inhibitor are housed in the battery case. The positive electrode 10 includes a positive electrode current collector 12 and a positive electrode active material layer 14 which is formed on the current collector and which mainly contains a positive electrode active material. In addition, a conductive material layer 16 which mainly contains a conductive material is formed between the positive electrode active material layer 14 and the separator. A porosity of the conductive material layer 16 is 35% or more and 55% or less

    摘要： A nonaqueous electrolyte secondary battery includes an electrode body (20), a nonaqueous electrolytic solution, a battery case (80), and a bag-shaped film (10). The electrode body has a laminate structure in which a positive electrode (30) and a negative electrode (40) are laminated. The battery case accommodates the electrode body and the nonaqueous electrolytic solution. The bag-shaped film covers the electrode body to insulate the electrode body and an inner wall of the battery case from each other. An inner pressure of the battery case is adjusted to be 0.14 MPa to 0.23 MPa.

    摘要： A battery pack (2) includes a plurality of non-aqueous electrolyte single cells (10), each single cell being such that a rolled electrode body (16) is housed in a flat case (11); a plurality of spacers (20); and a banding member (5, 7). The rolled electrode body includes a collector portion (17, 18), and a power generating portion (16a). Each spacer (20) has at least one recessed portion provided on at least one surface that faces the adjacent single cell (10). A side plate (31) of the case that faces the surface of the spacer on which the recessed portion is provided includes a thick portion (31a) that contacts the power generating portion (16a) of the rolled electrode body (16) inside the case, and a thin portion (31b) that is thinner than the thick portion (31a) and is continuous with both sides of the thick portion (31a) in the rolling axis direction. The surface of the spacer (20) on which the recessed portion is provided abuts against the thick portion only.

    摘要： The present invention provides a lithium ion secondary battery in which an electrode assembly, in which a positive electrode sheet having a positive electrode mixture layer and a negative electrode sheet having a negative electrode mixture layer are overlain each other, is housed in a container together with a nonaqueous electrolyte solution. The negative electrode mixture layer includes a carbon material having at least in part a graphite structure as a negative active material. When S (m 2 ) represents a value obtained by calculating a total surface area of the negative electrode active material included in a region of the negative electrode mixture layer lying opposite the positive electrode mixture layer per 1 Ah of capacity of the battery, V represents a value obtained by calculating a total volume of pores included in the region of the negative electrode mixture layer per 1 Ah of capacity of the battery, and N represents the number of lithium ions included within the volume V of the nonaqueous electrolyte solution, the value α computed by the formula α = S × N is from 1 × 10 25 to 2.5 × 10 25 .
