rate of lead–acid battery exports from China, which declined at a stable rate after 2016. In 2018, the lead–acid battery export volume for China reached 190.23 million, whereas the import volume was only 10.94 million [16, 17]. This high-trade decit is one of the major causes of the relatively low lead-recycling rate in China.

1 Introduction. With the rapid development of the automobile industry, the production of lead–acid batteries (LABs) as the automotive ignition power source and energy storage devices has experienced enormous growth during the past few decades. [] Up to 11.7 million tons of refined lead (Pb) were used in the manufacture of LABs, accounting for over
All lead-acid batteries suffer from sulfation. It's just chemistry. Lead-acid batteries contain lead plates and a free-flowing solution of sulphuric acid. One of the inevitable byproducts of the plates and acid coming into contact is that lead sulfate will accumulate on the lead plates of the battery.
Hence, based on the minimum specific gravity of industrial lead paste slurry, the concentration of desulfurizer required for sodium-calcium double alkali lead paste desulfurization was estimated to be at least 2.32 mol/L. 3.2. Mechanism of a novel process of lead paste pre-desulfurization
NaOH was used as the direct desulfurizer for lead paste, and lime was used to regenerate NaOH from the mother liquid at sufficient concentrations for desulfurization.
The desulfurization of lead paste by regenerated alkali was as follows: (i) desulfurization was conducted by adding waste lead paste to a beaker containing a certain volume of regenerated NaOH solution and stirred. (ii) After the desulfurization reaction was complete, filter residue and filtrate were obtained by vacuum filtration.
A lead-acid battery acts as a store of power because of the reaction between the lead plates and the electrolyte. The reason that both sulfation and acid stratification cause batteries to lose power and the ability to accept charge is because they both reduce the contact between the lead plates and the active electrolyte.
1 billion vehicles worldwide use lead-acid batteries. Increasing environmental regulations and fluctuating virgin lead prices around the world have created the need for new technologies to recover the metal and manage processing waste. To address this difficulty, Dross Engineering has developed innovative lead recovery equipment
