0.1〜0.3重量%程度添加されている。2. Description of the Related Art Conventionally, several kinds of additives have been added to a negative electrode active material of a lead storage battery. One of them is lignin, which is a by-product in the production of pulp, used in combination with barium sulfate as an expander (shrinkproof agent) for the purpose of improving low-temperature high-rate discharge performance. About 4% by weight is added. In addition to the above, carbon is added in an amount of about 0.1 to 0.3% by weight for the purpose of improving current efficiency during chemical conversion.

放電性能や寿命性能が改善されると考えられている。[0003] Lignin is adsorbed on the surface of the negative electrode active material,
It is considered to have the effect of increasing the size of the lead sulfate crystals generated during discharge and suppressing the decrease in the specific surface area of the active material during charging, which results in high rate discharge performance at low temperatures and life performance. It is believed to be improved.

低下するという問題があった。However, the lignin adsorbed on the surface of the active material is gradually eluted into the electrolytic solution from the negative electrode plate during charging / discharging, and the further eluted lignin is oxidized on the positive electrode plate to form carbon dioxide. However, there is a problem that the effect does not last for a long time. In addition, when a large amount of lignin is added in order to maintain the effect for a long period of time, there is a problem that charge acceptability is lowered, charge is insufficient, and the capacity is rather lowered.

ある。According to the present invention, 0.5 to 1.0% by weight of lignin and 1.0 to 2.0% by weight of carbon are added to a negative electrode active material.
It is intended to provide a lead-acid battery which has a long-lasting effect of an expander and is excellent in charge acceptance. That is, a large amount of lignin is added to the negative electrode active material to decrease the charge acceptability, so by adding a large amount of carbon to supplement the charge acceptability, the effect of the expander is prolonged without decreasing the charge acceptability. It is intended to be maintained for a period.

FIG. 1 shows the 20 A discharge performance during the life cycle, and FIG. 2 shows the low temperature high rate discharge (150 A discharge at −15 ° C.) performance during the life cycle. In the conventional battery (Battery N0.5), the low-temperature high-rate discharge capacity is remarkably reduced from the beginning of its life. This is because lignin eluted from the negative electrode plate during the life cycle. In addition, the battery (battery No. 6) in which only the lignin was increased to 1.0% had poor charge acceptance and became insufficiently charged.
Both the 20 A discharge and the low temperature high rate discharge gradually decreased in capacity from the beginning of the cycle. On the other hand, the battery containing only the increased amount of carbon (Battery No. 7) showed almost the same capacity transition as the conventional product in both 20 A discharge and low temperature high rate discharge.

There was no sudden decrease in capacity at the beginning of life, and there was no capacity decrease due to insufficient charging, and good low-temperature high-rate discharge performance was exhibited until the end of life.
