In this instructable a novel (resistive) pulsing approach is described for driving the lead-sulfate back into solution that is faster than the more traditional inductive method. Sulfation is not the only aging mode in lead acid batteries, so while desulfation may extend the life, it will not do so indefinitely.
This is what desulfation (desulphation)is about. Batteries are subject to an internal discharge, also called self-discharge. This rate is determined by the battery type, and the metallurgy of the lead used in its construction. Wet cells, with the cavities inside for electrolyte, use a lead-antimony alloy to increase mechanical strength.
Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.
Lead paste was firstly desulfurized with sodium carbonate, in the meanwhile lead sulfate was converted into lead carbonate and the form of lead metal and lead oxides remained unchanged, and then the desulfurized lead paste was reduced by charcoal under vacuum.
With the wide application of lead acid battery, spent lead acid battery has become a serious problem to environmental protection and human health. Though spent lead acid battery can be a contaminant if not handled properly, it is also an important resource.
The lead dioxide (PbO 2) plate reacts with the sulfuric acid (H 2 SO 4) electrolyte resulting in hydrogen ions and oxygen ions (which make water) and lead sulfate (PbSO 4) on the plate. The lead plate reacts with the electrolyte (sulfuric acid) and leaves lead sulfate (PbSO 4), and a free electron.
