きる特性を持った負極が必要となってきた。Conventional technology In general, in sealed alkaline storage batteries, in order to prevent the internal pressure from increasing due to gas generation due to water electrolysis during overcharging, (1) oxygen gas generated from the positive electrode is a charging product of the negative electrode. By making the electrochemical capacity of the active material filled in the negative electrode larger than the electrochemical capacity of the active material filled in the positive electrode, hydrogen gas generation from the negative electrode is prevented. This method is being used. However, even when these methods are used, the internal pressure level during overcharging is high, and therefore a negative electrode with characteristics that can further prevent the internal pressure of the battery from increasing has become necessary.

c shows a battery using a negative electrode for comparison. In addition, the equilibrium pressure after discharge indicates the residual hydrogen pressure within the battery. As is clear from this result, a battery using a negative electrode & and C with a layer containing graphite powder formed on the electrode surface is different from a battery using a negative electrode with no layer formed on the electrode surface. The internal pressure is significantly reduced compared to the previous model. This is thought to be because the formation of a conductive layer on the electrode surface made it easier for metal cadmium, which is involved in gas absorption, to be generated near the surface. Further, in battery a using negative electrode B, in which graphite powder adsorbed with palladium was used for the surface layer, the residual hydrogen pressure after discharge was zero. This is thought to be because the generated hydrogen gas was electrochemically absorbed by the action of the catalyst. Furthermore, when comparing the internal pressure curve of battery a with the internal pressure curve of battery C using negative electrode C using graphite powder on which palladium is not adsorbed, the shape is almost the same, so the action of the catalyst is mainly caused by hydrogen gas. It is thought that this is due to absorption.

る水素ガス消失をより円滑に行える。FIG. 2 shows the relationship between battery internal pressure and time in an internal pressure test during charging after battery storage. As is clear from the figure, results similar to those obtained in the internal pressure test during overcharging were obtained in this test as well. By overcharging, the cadmium hydroxide in the negative electrode changes to metallic cadmium, and when there is no longer enough cadmium hydroxide to accept charge, hydrogen gas is generated if charging is continued. Also,
When a battery is stored, γ-type cadmium hydroxide, which easily accepts charge, changes to β-type cadmium hydroxide, which does not easily accept charge, so hydrogen gas is generated when the battery is charged. In this embodiment, hydrogen gas can be electrochemically absorbed in any case. Furthermore, by forming a porous film of fluororesin on the surface of the layer, a gas phase for gas introduction can be secured, and hydrogen gas can be more smoothly eliminated by the catalyst.

If the layer becomes thicker than the above, actual charging and discharging becomes impossible, so it can be said that the appropriate layer thickness is 0.6 to 20 μm. In addition, although polyvinyl alcohol was used as the binder in the examples, similar effects can be obtained by using other water-soluble binders such as methylcellulose or water-insoluble binders such as fluororesin. is obtained.
