Typical lead recovery methods that do not require cell crushing prior to the melting stage include water jacket furnace, reverberatory furnace, electric furnace, and long/short rotary furnaces.
What is lead-acid battery recycling?
As already mentioned, lead-acid battery recycling has a long tradition, especially in industrialised countries. The battery and scrap trade takes back spent batteries free of charge or even pays the metal value.
Regarding the treatment of hazardous waste, lead-acid batteries are the most damaging waste fraction. Phasing out lead-acid batteries for lithium-ion is currently too expensive to be feasible in the unregulated sector, and the capacity of governments to enforce such a measure is limited.
What are lead-acid batteries used for?
Lead-acid batteries (LABs) are widely used in electric bicycles, motor vehicles, communication stations, and energy storage systems because they utilize readily available raw materials while providing stable voltage, safety and reliability, and high resource utilization. China produces a large number of waste lead-acid batteries (WLABs).
Does China recycle lead-acid batteries?
China produces a large number of waste lead-acid batteries (WLABs). However, because of the poor state of the country's collection system, China's formal recycling rate is much lower than that of developed countries and regions, posing a serious threat to the environment and human health.
Where are lead batteries recycled?
In developing countries spent lead batteries are recycled both in industrial facilities and by informal small enterprises. Industrial recycling smelters use both the grid metal and the lead-containing paste to produce secondary lead.
Will lead-acid batteries continue to play a role in off-grid electrification?
Therefore, lead-acid batteries are expected to continue to play a fundamental role in off-grid electrification, and the adequate management of lead waste should be one of the highest priorities in any waste management strategy.
