<p>A cell developed to solve the problem of a conventional cell that a large short-circuit current flows when the temperature of the cell is raised due to internal short circuit, whereby the temperature of the cell is further raised due to heat buildup and a further increased short-circuit current flows. Specifically a cell in which a positive electrode (1) contains an active material containing nickel, and at least either the positive electrode (1) or a negative electrode (2) is provided with an active material layer (6) containing an active material (8) and an electron conductive material (9) in contact with the active material (8), while an electrolytic layer (3) is sandwiched between the positive electrode (1) and the negative electrode (2). The electron conductive material (9) contains an electrically conductive filler and a resin and has a resistance increasing with temperature.</p> |
