Silicate storage battery with high stability

Abstract

The invention discloses a silicate storage battery with high stability. A formation method comprises the following steps of selecting a constant negative pole plate groove; allowing a pole plate to enter the groove in a live-line way, and performing formation by a constant negative formation method; and discharging for 0.5 hours with a current at the last stage of formation, taking out the pole plate of the groove, and directly drying without washing. A few amount of floating powder is generated on a surface of the pole plate generated by the formation method, the flowing powder can be reducedby about 20%, so that the service performance of the battery is improved, the service lifetime of the battery is prolonged, and the production environment of staff is also improved.

Description

technical field [0001] The invention relates to a method for forming polar plates in the production of silicic acid accumulators, in particular to a silicic acid accumulator with high performance. Background technique [0002] As we all know, silicon and its compounds are toxic to various tissues of the human body. The way of poisoning can be to inhale its vapor or dust through the respiratory tract, then enter the blood through the respiratory tract or absorb it through the digestive tract, and enter the blood circulation to cause poisoning. However, there is a lot of floating powder on the surface of the pole plate, which will make the production environment very bad, which is especially unfavorable to the health of the on-site employees. [0003] In addition, more floating powder on the surface of the plate will also have an adverse effect on battery performance. First, the main component of the floating powder on the surface of the negative plate is silicon dioxide. Aft...

AI Technical Summary

Problems solved by technology

However, there are more floating powder on the surface of the plate, which will make the production environment very bad, which is especially unfavorable to the health of the on-site employees.

[0003] In addition, more floating powder on the surface of the plate will also have an adverse effect on battery performance

First, the main component of the floating powder on the surface of the negative plate is silicon dioxide. After entering the separator, it will react with sulfuric acid to form silicon sulfate, which will block the "channel" in the separator, thus hindering the chemical process of charging and discharging the battery. The reaction reduces the battery capacity; the main component of the floating powder on the surface of the negative plate is silicon, which is a kind of conductor. After entering the separator, the negative and negative plates will be short-circuited, which also affects the performance of the battery.

Second, there are more floating powder on the polar plate, which also means that the strength of the polar plate is poor, and the polar plate is easy to loosen and drop the grease during vibration.
