Desulfating a lead-acid battery with a battery reconditioner or desulfator is considered the conventional method of desulfurization. It is a method where the device generates pulses with high-frequency and …
Introduction The global annual output of refined lead is up to 11.7 million tons in 2020, of which more than 85% are used in the manufacture of lead-acid batteries in the forms of lead oxide and lead alloy [1], [2]. However, the …
A green, efficient, and short route for recovering metal lead from spent lead-acid batteries has a great advantage in both environmental protection and sustainable development of lead industry. This paper developed a new scheme to recover metal lead by direct electrolysis in (NH4)2SO4 solution with desulfurized lead paste. Cyclic voltammetry …
The voltage applied when attempting to desulfate a battery depends on the battery''s type and size. For lead-acid batteries, a voltage of 14.4 to 15 volts is recommended. For AGM batteries, a voltage of 15.5 to 16 volts is …

In the reaction process of carbonate desulfurization lead paste, the produced PbCO 3 is easily wrapped in the outer periphery of PbSO 4 to form a product layer, hindering the mass transfer process. Therefore, it is necessary to break the PbCO 3 product layer. In this work, the rotor stator-reinforced reactor was selected as the …
The purpose of our research is to find an optimal method for the recycling of used lead–acid batteries in order to recover lead from positive (PAM) and negative (NAM) active masses and obtain lead oxide …
2.2. Procedure2.2.1. Solubility measurement The experiments were carried out in a round-bottom flask with mechanical agitation at room temperature. Firstly, sodium tartrate was used to prepare the 200 mL solution with a certain C 4 H 4 O 6 2− concentration, and nitric acid (16 mol/L) was added to adjust the pH to the required value. …
The spent lead-acid battery is primarily composed of lead paste, waste acid electrolyte, lead alloy grid, polymer container and some other parts including connecting rods [11]. Among them, the spent lead paste with complex compositions, mainly comprising PbSO 4, PbO 2, PbO and a small amount of lead metal, is the most difficult …
Because lead-acid batteries lose effectiveness due to the effect of "irreversible sulfide", it is recognized that lead sulfate will gradually condense into small particles along with an increase in "irreversible sulfide". During the desulfurization process, the surface of PbSO 4 particles will gradually be covered with a layer of much fewer …

Through controlling the thermodynamic conditions, 99.53% of zero-valent lead (lead grid) was transformed into the layered orthogonal β-lead oxide with merely 0.0494% impurities, and 99.79% of tetravalent lead (lead dioxide in the lead paste) was converted into divalent lead (lead sulfate) in sulfuric acid solution.
Lead-oxidized powder is used as a direct raw material for lead–acid storage battery production, which is still mainly prepared by the ball mill or baton pot …
The recovery of lead from spent lead acid battery paste (SLP) is not only related to the sustainable development of the lead industry, but also to the sustainable evolution environment. An innovative process is proposed for the recovery of high purity metallic lead from spent lead acid battery paste (SLP) by electrodeposition at 333–353 …

Lead-acid batteries contain significant amount of lead that is an important material for emerging perovskite solar cells. Here, we successfully recovered lead from lead-acid battery. Anode and cathode lead mud reacted with acetic acid (CH 3 COOH), and the produced high purity lead acetate (Pb(Ac) 2) was tested with FTIR and XRD.. …
Analytical grade lead oxide and spent lead acid battery were used as experimental materials. Before desulfurization, the battery paste was washed by distilled water to remove acid. The battery pastes were rinsed by filtration for about 10 min.The amounts of water ...
Highlights 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 …
