Electrode plate of light lead storage battery

Abstract

The invention relates to a storage battery, in particular to an electrode plate of a light lead storage battery. The electrode plate comprises a grid and active substance and is characterized in that the grid is made by pressing graphite material and the active substance is directly adhered on the surface of the grid. The graphite material is adopted to make the grid of the lead storage battery, the active substance is retained, and the weight of the lead storage battery is reduced; and the grid is made from the graphite instead of lead, thus lead fume in a lead grid casting process is avoided, lead consumption is saved by about 40%, the problem that short circuit is caused by growth of the grid in the use process of the battery can be solved to reduce fault, and the reliability is improved. In the invention, the grid does not adopt lead, thus not only is the storing capacity of the battery improved, but also the grade of the product is improved.

Description

Electrode plates for light lead storage batteries technical field The invention relates to a storage battery, in particular to an electrode plate of a light lead storage battery. Background technique The structure of the lead-acid battery is composed of positive and negative plates, bus bars, separators (membranes), electrolytes, exhaust valves, positive and negative poles, and shells (slots), while the positive and negative plates are composed of positive and negative grids. Composed of positive and negative active materials coated on it, the grid is made of lead, and then coated with lead paste on its surface, the weight of the lead-acid battery mainly comes from the plate, that is, the grid and the active material. For a long time, many people have plated lead on aluminum, plastic, copper and other materials, and then made grids. The purpose is to try to reduce the amount of lead used to reduce the weight of the battery. The grid made of aluminum or copper materials, M...

Problems solved by technology

For a long time, many people have plated lead on aluminum, plastic, copper and other materials, and then made grids. The purpose is to try to reduce the amount of lead used to reduce the weight of the battery. The grid made of aluminum or copper materials, Metal aluminum or metal copper will be corroded by the electro-liquid, which will lead to an increasing amount of impurities contained in the electro-liquid, which seriously affects the electric energy storage and power supply capacity of the lead-acid battery. However, due to the fact that the plastic substrate itself does not have conductivity, the quality of this lead-acid battery is very poor in actual use and cannot be applied
