It was also found that the life performance was improved when the average particle size of the carbon particles was 0.01 to 0.2 microns. The reason that the life performance is improved when carbon particles are included in the electrolytic solution is presumably because the carbon particles adhere to the positive / negative electrode plates, and as a result, the Pb ion precipitation reaction is improved.

In the same procedure as in Example 1, a positive electrode plate and a negative electrode plate were produced, and a plurality of electrode plate groups were produced. Next, after each electrode group was put in a battery case, an electrolytic solution was injected into the separator. Dilute sulfuric acid containing acetylene black as carbon particles was used for the electrolytic solution, and the average particle size or concentration of carbon particles was changed for each electrode plate group. After the formation of each electrode group, a sol solution composed of dilute sulfuric acid and colloidal silica was injected between the electrode group and the battery case to gel. Thus, a plurality of types of gel-retainer hybrid batteries having different electrolytes were obtained. The battery has a nominal voltage of 2V and a nominal capacity of 30Ah.

It was remarkably good at 0.05 g / cc. Also,
It has been found that when the average particle diameter of the carbon particles is 0.01 to 0.2 μm, the life performance is improved. The reason that the life performance of the gel-retainer hybrid battery is improved by the addition of the carbon particles is considered to be that the carbon particles adhere to the negative electrode plate, and as a result, the oxygen gas absorption reaction in the negative electrode plate is promoted.
