    摘要: Conventionally, the temperature of a cell rises to above 100°C if an inside short-circuit occurs and a large short-circuit current flows and generates heat. Therefore the temperature further rises because of the heat and hence the short-circuit current further increases. A cell according to the invention free from the problem and having an improved performance, comprises an electron conductive material the resistance of which increases with temperature and one of an electrode containing a predetermined amount of a conduction assisting agent, an electrode in which the ratio of the total amount of an electrode conductive material and a conduction assisting agent to that of an active material is a predetermined value, and an electrode in which the ratio of the particle size of a conduction assisting agent to that of an electron conductive material lies in a predetermined range.

    摘要: A cell developed to solve the problems 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, and that when an aluminum-laminated bag is used as a covering member in order to seal the cell body, the sealed port is apt to be opened due to temperature rise, leaving the problem of safety. Specifically a cell in which at least either a 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), and an electrolyte layer (3) is sandwiched between the positive electrode (1) and the negative electrode (2) thereby to constitute a cell body (11). The cell body is sealed with a covering member (14) made of aluminum (13) and a thermally fusible resin (12). The electron conductive material (9) contains an electrically conductive filler and a resin and has a resistance increasing with temperature.

    摘要: Conventional batteries are disadvantageous in that a firm outer case must be used to maintain an electrical connection between electrodes, which has been an obstacle to size reduction. Those in which each electrode and a separator are joined with an adhesive resin suffer from conflict between adhesive strength and battery characteristics. To solve these problems, it is an object of the invention to provide a battery which requires no outer case so as to realize reduction in thickness and weight and yet exhibits excellence in both battery characteristics and adhesive strength. A positive electrode, a negative electrode, and a separator are joined via an adhesive resin layer having at least one adhesive resin layer containing a filler. The adhesive resin layer has pores, which are filled with an electrolytic solution to exhibit sufficient ion conductivity thereby to improve battery characteristics and to retain adhesive strength.

    摘要: The conventional battery has such a problem that the size of the battery is not able to be reduced, because the battery must use a solid can to maintain the electrical connection between its electrodes. In such a battery in which each electrode is joined to a separator with an adhesive resin, in addition, the adhesive strength between the electrodes and a separator and the characteristics of the battery, particularly, the ion conductivity and internal resistance of the battery act as contradictory to each other. In order to solve these problems, the characteristics of the battery are enhanced by reducing the resistance between electrodes, namely, the internal resistance of the battery, while the insulating function to the electronic conduction between both electrodes and the ion conductivity are compatible with each other and, in addition, the weight, size, and thickness of the battery are reduced while maintaining the adhesive strength between both electrodes, so that the electrodes can be joined firmly to each other. The internal resistance of the battery is reduced by joining the anode and the cathode to each other with an adhesive resin layer provided at least with one filler-containing adhesive resin layer and, in addition, the characteristics of the battery are improved and the adhesive strength between the electrodes is maintained by forming the adhesive resin layer in a porous layer, so that the pores of the resin layer can be filled up with an electrolytic solution and the resin layer can have sufficiently high ion conductivity.
