α-PbO Recovery from Spent Lead Paste by Coalesced Reduction …
Recycling end-of-life lead acid batteries is essential for the recovery of lead oxide (active material of new laboratory assembly) from spent lead paste. In this approach, a low-temperature coalesced reduction and sulfur fixation process was introduced for the extraction of lead oxide from spent lead paste followed by wet chemical conversion and …
Synthesis and characterisation of tribasic lead sulphate as the negative active material of lead-acid battery …
Although tribasic lead sulphate (3BS) has been chemically prepared and found in the cured negative plates of lead-acid batteries (LABs), little was known about its behaviour if it is used directly as their negative active material (NAM). Here, we report a much more facile and energy-saving route to prepare phase pure 3BS powders: after β …
