    摘要： In case of a conventional battery having a laminated sheet material as a battery case for storing a battery body, the metal foil on the laminated sheet does not contact to either a positive electrode or a negative electrode and electric potential is unstable. Therefore, there was a problem that it was impossible to obtain electrical shielding effect. In order to maintain the function of the sealed part in the battery case, an extended part extended from the sealed part is disposed at a position where it overlaps with the positive electrode lead or the negative electrode lead, and by jointing the lead and the extended part with the conductive material piercing therethrough, the metal foil on the laminated sheet material of the battery case is electrically connected to the lead to maintain the electric potential of the battery case to the electric potential of the positive electrode or the negative electrode.

    摘要： Conventional batteries have a problem that, in case the battery temperature should rise to or above a temperature at which the separator melts or flows due to an internal short-circuit, etc., a large short-circuit current develops to generate heat at the part where the separator flows. It follows that the battery temperature further increases, which can result in a further increase of the short-circuit current. The invention has been completed to solve the abovementioned problem. It is an object of the invention to provide an electrode which increases its resistivity with temperature, a method of fabricating the electrode, and a battery using the electrode. Specifically, the electrode of the invention contains a resin which is in contact with an active material or a conducting agent and expands in volume with a rise in temperature.

    摘要： Conventional batteries have a problem that, in case the battery temperature should rise to 100° C. or higher due to an internal short-circuit, etc., a large short-circuit current develops to generate heat. It follows that the battery temperature further increases, which can result in a further increase of the short-circuit current. Further, some of electrode structures involve reduction in discharge capacity. These problems are solved by a battery in which an electron conductive material (9), being in contact with an active material (8) in an electrode, comprises a conductive filler and a resin so that the electrode may increase its resistivity with a temperature rise, and the ratio of the particle size of the electron conductive material (9) to that of the active material (8) is in a range of from 0.1 to 20.

    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, particularly ion conductivity and internal resistivity. To solve these problems, it is an object of the invention to reduce resistance between electrodes, i.e., internal resistance of a battery to improve battery characteristics while securing both insulation function against electron conduction and ion conductivity between electrodes and also to maintain adhesive strength enough to firmly join the electrodes thereby to provide a light, compact and thin battery. The internal resistivity can be diminished by joining a positive electrode and a negative electrode with 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.
