Plate producing method effectively improving floating powder pollution of negative electrode plate

Abstract

The invention discloses a plate producing method effectively improving floating powder pollution of a negative electrode plate. The method comprises the following steps of selecting a negative constant plate groove; feeding the plate charged with a negative constant method; at the end, performing current discharge for 0.5h at the last stage, grooving the plate, and directly drying the same withoutwashing. The plate produced by the method provided by the invention has less surface floating powder on the surface, and the floating powder can be reduced by about 20%, thereby improving the serviceperformance and service life of the battery and improving the production environment of the employee.

Description

technical field [0001] The invention relates to a pole plate method in the production of silicic acid storage batteries, in particular to a pole plate production method for effectively improving the floating powder pollution of the negative pole plate. 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 t...

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.
