    • 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.
    • 传统电池具有这样的问题,即电池的尺寸不能减小,因为电池必须使用固体罐来维持其电极之间的电连接。 在这样的各电极通过粘合树脂与隔膜接合的电池中,除此之外,电极与隔膜之间的粘合力以及电池的特性,特别是电池的离子传导性和内阻作为 相互矛盾。 为了解决这些问题,通过减小电极之间的电阻即电池的内阻来提高电池的特性,同时对两个电极之间的电子传导的绝缘功能与离子传导性彼此兼容 此外,在保持两个电极之间的粘合强度的同时减小电池的重量,尺寸和厚度,使得电极可以牢固地彼此连接。 通过使用至少具有一个含有填料的粘合树脂层的粘合树脂层将阳极和阴极彼此接合而降低电池的内阻,并且此外电池的特性得到改善并且粘合强度 通过在多孔层中形成粘合树脂层来维持电极之间的连接,从而树脂层的孔可以填充电解液,并且树脂层可以具有足够高的离子传导性。
