6 FAQs about [Lead-acid battery desulfurization and repair application]

Can a pulsing method extend the life of a lead acid battery?

Can spent lead acid batteries be reused?

Spent lead acid batteries are the main raw materials for the production of recycled lead (Jiang et al., 2019), which will gradually replace the primary lead. The lead-containing substances in spent lead acid batteries can be reused through proper recovery to decrease the exploitation of primary lead (Liu et al., 2018).

How to desulfurize lead paste by regenerated alkali?

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.

What is a direct desulfurizer for lead paste?

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.

How much desulfurizer is required for sodium-calcium double alkali lead paste slurry?

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

How to recover lead from a battery?

At present, pyrometallurgy and hydrometallurgy are the main methods to recover lead from the lead pastes of spent lead acid batteries (Ma and Qiu, 2015; Yu et al., 2019). Pyrometallurgy is reducing the lead-containing substances to metallic lead at high temperature.
