    摘要： An object is to provide a lithium ion secondary battery which maintains the electrical connections between each active material layer and a separator without using a firm housing, can have an increased energy density, can take an arbitrary shape, such as a thin shape, exhibits excellent charge and discharge characteristics, and has a large battery capacity. Positive and negative electrode active material particles are bonded to their respective current collectors to form a positive electrode and a negative electrode. The positive and the negative electrode active material layers are joined to a separator with a binder resin so that the joint strength between the separator and the positive and the negative electrode active material layers may be equal to or greater than the joint strength between the positive and the negative electrode active material layers and the respective current collectors to prepare a tabular laminated battery body having a plurality of electrode laminates. An electrolytic solution containing lithium ions is held in the voids possessed by the positive and the negative electrode active material layers and the separator to make an electrical connection between electrodes.

    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.
