Processes taking place in the paste of lead-acid battery plates
During the production of lead-acid batteries, when pasted and cured plates are soaked in H 2 SO 4 solution before formation, sulfuric acid reacts with the cured paste whereby the paste is sulfated. The reaction between H 2 SO 4 and the paste proceeds in a reaction layer between the zones of cured paste and sulfated paste. With the time of soaking, the reaction

Preparation of basic lead oxide from spent lead acid battery paste
A novel process was studied to recover lead as ultra-fine lead oxide from lead paste. The desulphurization rate of lead paste was 99.0% with Na 2 CO 3, NaHCO 3 or (NH 4) 2 CO 3. Around 98% of lead from desulphurized paste was converted to lead citrate precursor. Ultra-fine lead oxide with particle size of 100–500 nm could be obtained at 370 °C.

How much lead acid paste is produced per batch?
1,500 kg of lead acid paste per batch Depending on the production range this results in an output of 4,500 to 6,000 kg/h. Special software was developed for the processing of lead acid paste. Used with a modern process visualization system and PLC it enables all functions to be controlled and monitored.
What is the balance of a lead acid battery?
ern ad; the balance is electrolyte, separators, and the case. [edit] SeparatorsSeparators are used between the positive and negative plates of a lead acid battery to prevent short circuit through physical contact, mostly thro gh dendrites (‘treeing’), but also through shedding of the active material.Separators obstruct the f
What is the phase composition of lead powder?
Phase composition of the paste. It depends on H 2 SO 4 /LO ratio (LO is the oxidized lead powder), temperature, additives and time of mixing. It has been established that the paste is a non-equilibrium system consisting of crystalline basic lead sulfates and oxides, and amorphous sulfate-containing components.
Can I use stoclting wet paste in a battery making unit?
Stoclting wet paste for use in factories with no mixing facilities It is sometimes necessary to supply a small battery making unit with premixed paste. In these circumstances, it is preferable to avoid high sulfation mixes and formulate the paste with medium or low sulfation and adjust the paste density with the water content.
What causes lead-in-air concentrations in the pasting of plates?
There are two areas that generate lead-in-air concentrations in the pasting of plates. At the hopper, paste tends to stick to the top edges of the hopper walls and dry out. This dry paste is easily dislodged whenever the hopper is raised to clear a plate jam and is dropped back into the pasting position.
What is a lead-acid battery grid?
As an important part of lead-acid batteries, the grid is mainly used to support active substances and conduct current. Currently, Pb-Ca-Sn-Al alloys are widely used as materials for valve-regulated lead-acid battery grids.
