Recycling lead from wasted lead acid batteries is related to not only the sustainable development of lead-acid battery industry, but also the reduction of the lead pollution to the environment.
The lead acid battery has been widely used in automobile, energy storage and many other fields and domination of global secondary battery market with sharing about 50% . Since the positive electrode and negative electrode active materials are composed of PbO 2 /PbSO 4 and Pb/PbSO 4, lead is the most important raw material of lead acid batteries.
As an end of life lead acid battery facility, Enva provide a complete battery recycling service for all types of lead acid batteries, using the latest technology to enable us to extract 99.5% of lead ready for re-use in the production of batteries and other lead-based products.
Since the positive electrode and negative electrode active materials are composed of PbO 2 /PbSO 4 and Pb/PbSO 4, lead is the most important raw material of lead acid batteries. In 2010, the world's annual refined lead output reached up to 9.3 million tons, of which about 86% was consumed in the manufacture of lead acid batteries [2], [3].
This paper reports a new lead recovery method, in which high purity metallic Pb is directly produced by electrolyzing PbO obtained from waste lead acid batteries in alkaline solution.
The current efficiency is as high as 99.9% and the electrolytic lead recovery rate reaches up to 99.8%. In addition, the new recovery process avoids the emission of lead effluent by means of the recycling of the waste electrolyte. Therefore, it is a lead recovery process of low energy consumption and environmental friendliness.
