点があった。In the conventional storage batteries mentioned above, zinc, which is the negative electrode active material of the zinc electrode plate, has a considerably high solubility as syndicated ions in the alkaline electrolyte, and zinc dendrites grow during charging, causing internal short circuits and shortening the cycle life. But there was a shortcoming.

。In order to solve this problem, there is a method in which a large number of microporous film separators are interposed between a zinc electrode plate and a nickel electrode plate. According to this method, dendrite growth can be suppressed to some extent, but on the other hand, since there are no pores large enough to allow gas to pass through, oxygen gas diffusion from the nickel electrode is inhibited, and the oxygen absorption effect of the zinc electrode is inhibited. Since this is preferentially carried out at the periphery of the electrode plate, this promotes changes in the shape of the electrode plate, resulting in a decrease in cycle life and utilization rate. Therefore,
In order to improve oxygen gas diffusion and ensure gas absorption by the entire surface of the electrode plate, it has been proposed to insert a polypropylene nonwoven fabric between the zinc electrode plate and the microporous film separator. This method does not cause the inconvenience that the effect of preventing diffusion and dendrite growth is lost, and in addition, during battery assembly, the work of stacking and aligning cell elements consisting of zinc electrode plates, separators, and nickel electrode plates and correctly assembling them in the battery container is troublesome. This brings about such inconvenience as

The present invention provides a cell element composite comprising a non-woven fabric or woven fabric separator bound to at least one side of a horizontal zinc plate with a binder.

。In this composite, the non-woven fabric or woven fabric separator is bound together with a binder to the surface of the zinc electrode plate, so air bubbles do not enter between the surface of the zinc electrode plate and the non-woven fabric separator, and therefore, the growth of dendrites is prevented. can. In addition, oxygen gas from the positive electrode is absorbed on the entire surface of the zinc electrode plate through numerous holes on the entire surface of the non-woven fabric or woven fabric separator. Deformation of the electrode plate is prevented. In addition, when the nonwoven fabric or woven fabric separator uses polyvinyl alcohol as a binder, which serves as a liquid retaining layer, and binds the zinc electrode plate and the nonwoven fabric separator to each other by impregnation coating, the nonwoven fabric or woven fabric separator can swell with an alkaline electrolyte. However, it does not impair liquid permeability or gas permeability.
When used as a zinc-sealed battery, it provides a long-life battery.

It is composed of the following. To describe one example of the manufacturing method of this cell element composite 1, for example, polytetrafluoroethylene is added as a binder to zinc oxide and zinc powder, water is added to these, and the resulting paste is kneaded into a sheet shape. This is then crimped onto a metal porous current collector plate made of copper or the like from both sides to form a zinc electrode plate 2, and then nylon nonwoven fabric separators 3 are crimped onto both sides of this zinc electrode plate 2. is immersed in a binder solution.

る一方、不織布の内外面に均一に付着する。As the binder, a water-soluble binder, especially a polyvinyl alcohol aqueous solution is preferable.The polyvinyl aqueous solution penetrates through the countless small holes of the nonwoven fabric separator 3 and reaches the two surfaces of the zinc electrode plate, thereby forming a bond with the zinc electrode plate 2. It penetrates into the slight gap at the mutual interface with the nylon nonwoven fabric separator 3 and adheres thereto, while also adhering uniformly to the inner and outer surfaces of the nonwoven fabric.

A cell can be constructed simply by laminating the parts, and compared to the conventional cell construction made by laminating cell elements consisting of three parts: a zinc electrode plate, a separator, and a positive electrode plate, the number of assembled parts can be reduced. This simplifies the assembly work and also the work of accommodating the battery in the battery container.
