供するものである。Conventional technology In a type of battery (Fig. 4) in which the negative electrode plate 10 and the positive electrode plate 30, which serve as electrode plates, are assembled into the battery via a separator, conventional methods are used to maintain the active material in the shape of the electrode plates. hand,
The active material is sprayed as a powder or made into a paste (a mixture of the active material and additives in a solvent) to keep it attached.
Alternatively, an electrode plate made of a base material holding an active material can be manufactured by impregnating a conductive base material in a solution in which the active material component is dissolved or dispersed. In the case of the electrode plate used, although the conductivity between the active material and the base material is good, the volume of the base material per volume of the electrode plate is large, and as a result, the amount of active material is small, and the battery capacity is small.Also, the price of the base material is included. As for the strength of the electrode plate, since the active material is attached to the base material, the retention force of the active material part is weak (and some particles may fall off), but the present invention (lighter, cheaper, This provides an electrode plate with a large battery capacity.

である。Means for Solving the Problems The present invention is a method for solving the above-mentioned problems.The present invention has a structure in which an electrode plate for a battery is formed by kneading and curing an active material part and a polymer binder to form an electrode plate. In this method, an electrode plate is formed only from a polymer binder and an active material without using a base material.

〜(Left below) Soluble Nylene Herbal Benzyl Alcohol The paste consisting of the above composition is applied using a manufacturing apparatus as shown in FIG. Apply the paste 4 uniformly to the thin film forming mold 2 using the roller 1 through the slurry 5. Its q vibration is 1 at 90℃ as shown in Figure 2.
Evaporate the muff solvent for 2 hours. ＼Due to the coating, the plate 3 is hardened and formed. (Figure 3)
has strong mechanical strength and maintains sufficient strength even when formed into a spiral shape. In addition, it is easy to cut, and the electrode plate can be freely designed in one E3 function.
t'7) As a result of the experiment, the capacity of the electrode plate was sufficient considering the theoretical capacity of the active material (Figure 5). Compared to the amount of active material, ζ friend: 10% compared to conventional scraping board
It is possible to increase the amount of active material by about 40% and obtain an electrode that exhibits high capacity even with the same electrode plate volume.It is also possible to use alkali-resistant rubber as a polymer binder. Effects of the Invention With the present invention, the amount of active material can be increased without changing the electrode volume, resulting in a battery with high capacity.Also, since it does not contain a conductive base material, the weight of the electrode plate can be reduced, resulting in a lighter battery. The industrial value as a battery electrode plate is extremely high (
