Description of the Related Art Conventional batteries generally have a structure in which a positive electrode and a negative electrode form separate blocks and face each other via a separator containing an electrolyte. However, the battery is lightweight and has high energy consumption. In order to increase the density and the like, like a lithium battery, a positive electrode material, a positive electrode current collector, a positive electrode material, a separator containing an electrolyte, a negative electrode material, a negative electrode current collector, each sheet of the negative electrode material are stacked and spirally wound, There is a structure in which the spirally wound battery element body is housed in a cylindrical case, and the upper surface of the case serves as a positive electrode terminal and the lower surface of the case serves as a negative electrode terminal. However, according to this structure, since the battery shape is limited to the conventional cylindrical shape, there is a problem that space efficiency is poor and an occupied space becomes large when mounting on a substrate or the like.

Since the negative electrode has a spiral shape or a comb shape and the terminal electrode is formed on the outer surface integrally with the positive electrode and the negative electrode or as a separate member, it is not necessary to provide the terminal electrode by using the packaging material. Further, according to the manufacturing method of the present invention, a product in which these positive electrode and negative electrode can be used as terminal electrodes is manufactured. Further, by making the entire shape of the battery into a hexahedral shape, it is possible to set the battery without wasting space when mounting it on a substrate or the like.

A positive electrode 1 is formed by bonding a positive electrode active material such as LiCoO 2 together with a conductive powder made of graphite with a binder made of resin or the like on both sides of a metal film (paste) 2a such as Al serving as a current collector. A positive electrode material 1b is provided, and a negative electrode material 2b is formed by binding graphite as a negative electrode active material with a binder on both sides of a metal film (paste) 2a, which is also a current collector for the negative electrode 2, such as Cu.

An example is shown in which the battery 5 is set by bringing the positive electrode 1 and the negative electrode 2 which also serve as terminal electrodes into contact with each other. Since the terminal electrodes are integrally formed on the outer surface of the battery in this manner, they can be easily mounted on the substrate 6 and can be easily set in the holder 8, and a package material is provided and the terminal electrodes are attached thereto. Space saving can be achieved compared to the ones. Further, the hexahedron structure reduces the waste of the mounting space as compared with the conventional cylindrical battery.

In this example, a battery is produced by stacking a plurality of layers a to n in which a comb-shaped positive electrode 1 and a negative electrode 2 are meshed with each other so as to face each other with an electrolyte 3 in between. In the case of this example, as in the case of the spiral type, as shown in FIG. 7, the outermost portions of the positive electrode 1 and the negative electrode 2 are formed thicker than the other portions and are cut with a cutting margin W. Thus, a battery in which the positive electrode 1 and the negative electrode 2 are exposed on the outer surface is manufactured. Further, also in the case of this example, the terminal electrodes 9, 10 or the exterior body 11 may be provided on the outer surface as in the above example.
