Abstract

PURPOSE:To increase adhesion of an active mass to an electrode plate by applying the mixture obtained by mixing powder or particle zinc, short fibers, and a binder on a punched metal substrate, and press-fixing zinc active mass on its outside. CONSTITUTION:Both sides of a nickel plated iron punched metal substrate 1 are coated with the mixture formed by mixing powder or particle zinc, short fibers, and a binder such as PVA, CMC, and dried to form a mixture layer 2. A zinc active mass layer 3 is fixed by applying pressure with a press on the outside of the mixture layer 2 to form the electrode plate for a storage battery. This electrode plate has many advantages such as no falling off of zinc active mass, long life, and low cost.

提供せんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a storage battery electrode plate, and aims to provide a storage battery electrode plate in which the adhesion strength of a zinc active material to a substrate surface is increased.

従来亜鉛極を負極とする蓄電池極板としては、エキスバ
ンドメタル、金網等が使用されている。Conventionally, expanded metal, wire mesh, etc. have been used as electrode plates for storage batteries with zinc electrodes as negative electrodes.

しかしこのものはノ譬ンチンダメタル（打抜き方式によ

った。But iron, nickel, etc./? If a zinc active material is pressed directly onto a soldering metal substrate or a material coated with zinc, the adhesion will be extremely poor.To improve this, the holes in the soldering metal substrate are provided with holes to improve the adhesion. Although attempts have been made to improve this, the work involved in the manufacturing process of the substrate is extremely difficult and impractical.

質を加圧して固定せしめたものである。The present invention has been made in view of the current situation and as a result of extensive research, we have discovered a storage battery electrode plate that significantly improves the adhesion of the zinc active material by providing protrusions on the bent metal substrate. That is, in the present invention, a mixture of powdered or granular zinc and single fibers mixed with a binder is applied to the substrate surface using a non-quantitated metal method, and a zinc active material is fixed on the outside by applying pressure. It was forced upon me.

性を有するアクｙ々繊維が好ましい、又結着剤としては
例えばポリビニルアルコール水溶液、ＣＭＣを使用する
ものである。In the present invention, the single fibers for constituting the adhesion promoter material are not particularly limited, but preferably alkali-resistant aqueous fibers are used, and as the binder, for example, polyvinyl alcohol aqueous solution or CMC is used. It is something to do.

そして単繊維を用いる理由はノ母ンチングメタル基板面

しめんとするものである。The reason for using single fibers is to provide protrusions on the surface of the base metal substrate to strengthen the ethical bond with the zinc active material.

また亜鉛は導電剤としての役割を果すものである。Zinc also serves as a conductive agent.

2-Immerse it in a polyvinyl alcohol aqueous solution for several minutes and then dry it.Next, 1 part by weight of acrylic fiber was added to 100 weight INK of zinc powder, and 2% of this was mixed with a jelipinyl alcohol aqueous solution in a paste-like mixture. The above-mentioned substrate is immersed in water and then dried to provide protruding mixture layers 2 on both sides of the axillary substrate. Thereafter, the zinc active material layer 3 is fixed to the outside of the mixture layer 2 by applying pressure using a press, and the electrode plate of the present invention is hung.
