Construction of Lead Acid Battery

As such the main battery container containing sulfuric acid and therefore material for the manufacture of lead-acid batteries of the vessel must be resistant to sulfuric acid. The material from which the container should be free also affects those impurities of sulfuric acid. Especially iron and manganese will not be tolerated. Glass, lead-lined timber, hard rubber, hard rubber asphalt compound, ceramic materials and molded plastic having the above characteristics, so lead-acid battery container is formed from any of those species. The container was tightly sealed with the cap. Because of these characteristics people buy cheap lead acid battery in Nairobi.

The upper deck has three holes, a shed on each side of the posts and in the middle for vent plug and allowing the electrolyte and gases escape. On inner bottom floor of lead acid battery holder, two ridges to grip the positive lead acid battery plates and a further two ribs keep the negative plates. The ridges or prisms serve as support for the plates while protecting them against short circuits arise otherwise because of the fall of the active material of the plates at the bottom of the container. The container is most basic part of the construction of lead acid battery

Lead Acid Battery Plates

There are generally two methods of producing the active material of the cell and attach it leads to records.  We know the names of their inventors.

Plant Plate

Plant process

This process took two sheets of lead and plunged into dilute H2SO4. When a current in the lead acid cell transferred from an external supply, then as a result of electrolysis, hydrogen and oxygen are developed. At anode, put pilot oxygen attacks in PbO2 while cathode is unaffected because hydrogen is not connected with Pb may form.

If the cell is now discharged and peroxide-coated cathode plate becomes, so the hydrogen form and oxygen combine to form lead dioxide water, PB2 + 2H2 → Pb + 2H2O

Meanwhile, the oxygen feed to the anode lead and PbO2 is formed by the reaction. Thus, the anode becomes lead dioxide film covering.

By reversing the current, or by continuous charging and discharging of the film will become increasingly thick PbO2, cell polarity will require increasingly long time to reverse. After two stereotype by hundreds reversal will acquire lead peroxide sufficiently thick enough to handle high-capacity skin. Production of a positive electrode plate formed of a process called. The negative electrode plate of lead-acid battery is the same process.

Structure of Plant Plate

As can be seen, since the active material consists of a Plant plate formed with a thin layer from the surface of the lead plates PbO2, it must be expected to have a large surface area, to get it a significant volume. Surface area of ​​the lead-acid battery plates can be increased by slots or stacked. The figure shows the Plant positive plate pure lead grid which consists of finely laminated surface. The structure of these panels is reinforced by laminating a large number of fine vertical ribs which is incorporated by horizontal interval

Faure Plate

Faure in the process, the active material is applied mechanically, rather than by the electrolysis itself developed as a lead plate Planet process. Active substance, it is in the red lead (Pb3O4) or a lead oxide (PBO) or both as a mixture of various proportions were pressed into a thin gap also serves as a lead grid current conductor. Paste with the active material of the plate was dried, cured and assembled at the gate of the proportion of weak sulfuric acid solution after. Lead batteries must be long-term affordability of inactivity, with or without an electrolyte solution. Long-term storage, if present in the cell solution may result in insufficient power. This motivates people to buy cheap lead acid battery in Nairobi.
