Principle of desulfurization of lead-acid batteries

The treatment of spent lead paste is essential for the recycling of spent lead-acid batteries. In this study, we propose a facile route for the recovery of lead from spent lead paste by pre-desulfurization followed by low-temperature reduction smelting. The effects of two desulfurization methods, i.e., high-

Lead-Acid Battery Basics

Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.

Answer To The Question: Battery Desulfators

A 12 volt lead acid battery fully charged has a voltage of 15.2 volts. Because they are deliberately under voltage charged sulphation occurs. If a 12 volt battery was charged with 17v minimum the battery would outlast the life of at least 4-5 cars. All battery''s used for off grid/solar should be nickel iron as they last for over 100 years and ...
