Organic acid leaching followed by calcination process shows a facile and mild route in recovery of spent lead-acid battery with low-emission of hazardous gases, which are the most studied processes for the recovery of spent lead paste.
The recycling technologies for the recovery of component materials from lead-acid batteries can be based on both hydrometallurgical and pyrometallurgical processes. Recycling through hydrometallurgy basically consists of the acid or base leaching of scrap to put the metals in a solution.
The method has been successfully used in industry production. Recycling lead from waste lead-acid batteries has substantial significance in environmental protection and economic growth. Bearing the merits of easy operation and large capacity, pyrometallurgy methods are mostly used for the regeneration of waste lead-acid battery (LABs).
Two technological challenges in hydrometallurgical recovery process for spent lead-acid battery are recognized as: removal of impurity elements (such as Fe and Ba) and loop reuse for reducing dosage of leaching reagents.
Typically, lead-acid batteries for vehicles contain an average of 7.94 kg lead and 5.68 liters of sulfuric acid . Lead-acid batteries which are improperly disposed of can corrode, thus releasing lead and sulfuric acid which can seep into the ground and contaminate the soil and the ground water.
The synthesized leady oxide is used as the active materials for battery assembly, and the preliminary testing of batteries show a good electrochemical performance [56, 57]. Fig. 5. SEM images of the calcination product (a) and the carbon skeleton (b), and sketches of calcination transfer-reaction model: (c) whole, and (d) in section .
