とができる利点を有する。According to the present invention, an electrolytic solution reservoir for reserving the electrolytic solution is provided even in a thin battery having a thickness of 0.5 mm or less according to the first aspect of the present invention.
The charge transfer rate at 0 ° C. or lower was increased about 10 times, and the utilization ratio of the active material could be increased from 60% to 60% to 70%. Further, the consumption of the electrolyte during storage and use was replenished by the electrolyte in the electrolyte reservoir part, and the initial battery capacity and energy efficiency were stabilized. Regarding the battery capacity, the theoretical capacity of about 180 mAh is about 17 after 60 days at 90 ° C and 90% humidity (accelerated storage test).
It was 0 mAh (it was about 120 mAh in the past). The energy efficiency is about 500 Wh / l, but it is about 493 Wh / l after the energization test at 20 ° C.
It became l. According to claim 2, a plurality of cuts, crevices or recesses are provided in the active material layer as an electrolytic solution reservoir, and the electrolytic solution is reserved inside them to replenish the entire active material with the electrolytic solution. I was able to. According to claim 3, a cavity is provided in the active material layer to store the electrolytic solution, and by making the opening small, it is possible to reduce a large concave portion on the surface in contact with the separator, and to screen the separator. When printing, for example, the printing surface becomes flat, the thickness of the separator becomes uniform, and it is possible to prevent a short circuit between the bipolar active materials. By opening the active material surface side of the counter electrode, the electrolytic solution can be supplemented in another step after the active material is held. According to claim 4, the bendability of the current collector is improved. After holding the active material according to the ninth and tenth aspects, a crack or the like can be easily formed in the active material layer by cracking, for example, rapid heating (drying). Further, by increasing the packing density of the active material, cracks can be provided without heating. With this method, a large number of fine cuts can be provided over the entire surface, which is mechanically impossible, so that the reserve effect of the electrolyte solution, that is, the electrolyte solution can be replenished to all parts of the active material. . Further, by using the polymer solid electrolyte according to claims 5 and 6, it is possible to form uniformly on the surface of the active material provided with cuts and recesses.
The solid electrolyte layer can easily absorb the depleted electrolytic solution. Since it is a non-aqueous solution, lithium or the like can be used as the negative electrode active material. Since the electrolyte is not depleted, the active material is prevented from being partially passivated and the utilization rate of the active material is prevented from decreasing. Further, according to the seventh and eighth aspects, the active material can be easily provided with the electrolyte solution reserve portion such as a cut or a recess. Furthermore, since the same cuts and recesses can be provided between the batteries, it is possible to produce batteries without quality variations. Further, in claim 7, there is an advantage that the packing density of the active material can be increased by pressing the active material after holding it on the surface of the current collector.

No. 3 was formed by pressing a Thomson blade, which was formed in a grid pattern in a cut, against the positive electrode active material 2 surface. Figure 3
Is disposed on the inner surface of a negative electrode current collector (a series of stainless steel having a thickness of about 10 μm) 4 having a thickness of 30 μm of a negative electrode active material 5 (metal lithium, lithium-aluminum alloy, carbon, etc. can be used). After that, the polymer solid electrolyte 6 was screen-printed thereon to a thickness of about 10 μm. After the solid polymer electrolyte 6 is made effective, the adhesive 7 is attached to the negative electrode current collector 4.
Glued to. The positive electrode thus produced and the negative electrode were assembled as shown in FIG. Before assembling, the electrolytic solution 8 was dropped on the surface of the positive electrode active material 2 and was also filled in the cut lines 3. By cutting such a series of batteries at a portion of the adhesive material 7 (corresponding to a portion indicated by a dotted line in FIG. 1 and corresponding to a portion indicated by an arrow in FIG. 4), each individual thickness is reduced to about 0. A battery of 0.2 mm was prepared.
