Desulfation in Lead-acid Batteries; a Novel (resistive) Approach: A major life-limiting problem with lead-acid batteries is that when discharged (partially or otherwise) the resulting lead-sulfate slowly transforms into an insoluble form that eventually disables the battery. (A charged battery is shown, where no l…
Request PDF | Recovery of Lead from Spent Lead Paste by Pre-desulfurization and Low-Temperature ... The treatment of spent lead paste is essential for the recycling of spent lead-acid batteries.
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 …
Herein, a novel electrochemical spent lead-acid battery recycling approach with ultra-low energy consumption is proposed in this work, which is achieved via coprocessing with desulfurization ...
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 …
