There are lead batteries and alkaline batteries. Among these, alkaline storage batteries are expected to have high reliability and can be made smaller and lighter, so small batteries are used for various portable devices, while large ones are widely used for industrial purposes.In these alkaline storage batteries, cadmium is used as the active material for the negative electrode. In addition to these, other areas include ship iron and hydrogen.

層化されてきている。However, although some air electrodes and silver oxide electrodes are used as positive electrodes, in most cases nickel electrodes are used. The pocket type has been replaced by the sintered type, which improves its properties, makes it possible to seal it, and expands its uses.In addition to the sintered type, high-capacity foamed types and felt types are being taken up and put into practical use. .

して電圧が低下し容量が減少する。Problems to be Solved by the Invention Nickel hydroxide, the active material of the nickel electrode, has almost no electronic conductivity in either charging or discharging states, and the electrode tends to swell with repeated charging and discharging, so it has sufficient characteristics and is long-lasting. Long-life non-sintered nickel electrodes have not yet appeared.
% In other words, if a large amount of other conductive agent with excellent electronic conductivity is added in order to increase the conductivity and improve the utilization rate of the active material, the absolute amount of the active material will decrease\ Also, swelling and falling off of the active material will occur. Increasing the amount of binder that is effective in suppressing this decreases the electron conductivity of the electrode.The permeability of the electrolyte into the electrode also decreases, resulting in a decrease in voltage and capacity.

。Means to solve the problem Screen, Expanded Meta/L (punched metal or other inexpensive conductive porous material with a two-dimensional structure is coated with nickel hydroxide, a conductive agent and a thermoplastic binder, and then made into a sheet. In this case, the thermoplastic binder is a styrene copolymer rubber resin, and the lyophilic separator is a woven fabric of polyamide or lyophilically treated polyolefin. It is preferable that the nonwoven fabric and the conductive agent contain at least cobalt, carbon, and nickel powders and fibers, but are not limited to these materials.

をＡとする。Therefore, by using thermoplastic resin as a binder and integrating it with a separator by heating and pressurizing, the active material inside the nickel electrode is fixed as a support and the surface is fixed by the separator, so expansion and contraction due to charging and discharging is suppressed and the characteristics decrease is significantly reduced. Note that using a lyophilic sebaleta can also solve the problem of a decrease in the utilization rate of the active material due to poor compatibility of the thermoplastic binder with the electrolyte. 8 doses of phosphorous graphite 6 doses of nickel powder
Acrylonitrile single iron fiber 0.0 as a reinforcing agent. To 8 parts of this, a 3% (by weight) toluene solution of a styrene-ethylene-butylene copolymer is added so that the amount of this resin is 4 to 5 parts based on the nickel hydroxide to form a paste. This paste has a thickness of 0.17mm and a hole diameter of 1.8mrrx.
It was applied to a nickel-plated punched metal plate made of iron with an aperture of 53% and smoothed through a 155 mm slit, then dried at 120°C for 1 hour.
The lead plate was cut to a length of 210 mm and attached by spot welding.Meanwhile, it was treated with concentrated sulfuric acid to make it lyophilic.
A 2 mm polypropylene non-woven fabric is distributed on both sides of the nickel electrode, and is integrated into a sandwich shape through a roller press machine heated to 160 t' to form a sealed nickel-cadmium battery using a sintered cadmium electrode known as a nine-part electrode. The electrolyte used was 20 g/l of lithium hydroxide dissolved in a caustic potassium aqueous solution with a specific gravity of 1.25.
