Abstract
A method for implementing full cycle regeneration of a waste lead acid battery is provided. The method includes the following steps. Step (1): the waste lead acid battery is smashed and separated so as to obtain grid lead, diachylon, plastic and waste electrolyte. Step (2): the obtained diachylon after being dried is positioned into an airtight reactor for desulphurization and deoxidation, wherein lead sulfate and the lead dioxide both in the diachylon react to obtain lead monoxide (PbO) and sulfur trioxide (SO). Step (3): the obtained lead monoxide is reduced by solid phase electrolysis in a wet way so that the lead monoxide is reduced into sponge lead.
