Have been used batteries are collected, an act to prevent their entry into the ecosystem, causing harm to the environment. A lot of heavy metals in an electrolyte solution and waste acid, waste alkali contained in the waste batteries. If thrown away, corruption battery will destroy our water, crops and land erosion our survival, our environment will be facing a huge threat. So we need to be discarded after use battery recycling, one can prevent the pollution of the environment, and secondly, the composition of which can be useful for reuse and conserve resources. Handle the volume of lead-acid batteries and lead-acid battery is large lead toxic, so in all kinds of batteries, a pioneer in recycling, so the process is also more comprehensive and constantly evolving. In the lead-acid battery scrap recycling technology, the process is the key sludge, waste lead-acid batteries sludge phase is mainly PbSO4, PbO2, PbO, Pb and so on. PbO2 which is the main component, which accounted for 41% by weight to 46% and 24% filler and 28% of the positive electrode mix filler. Therefore battery recycling process, PbO2 reduction effect has an important impact on the entire recovery technology, its reduction process and wet fire two. Fire is PbO2 and sludge other components PbSO4, PbO, etc. together in the metallurgical furnace smelting reduction to Pb. However, due to the high temperature Pb SO2 and dust generated second contamination, and high energy battery recycling agent, utilization is low, it will gradually be eliminated. Wet reducing agent is added to the conversion of lead compounds PbO2 reduction valence state under solution conditions. Reducing agents have been tried many kinds. Among them, the sulfuric acid solution FeSO4 PbO2 reduction method is more ideal, and has an industrial application. Reducing the use of steel pickling wastewater can be formulated by Waste. Ni-MH batteries, lithium-ion batteries with new development in recent years, hand-held phones and electronic devices get a lot of applications. In Japan, Ni-MH battery production, in 1992 amounted to 18 million battery recycling project in 1993 amounted to 70 million battery recycling, to 2000 accounted for nearly 50% market share. Can be expected in the near future, there will be a lot of waste Ni-MH battery production. These waste Ni-MH battery positive and negative material contains a lot of useful metals, such as nickel, cobalt and rare earth. Therefore, recycling Ni-MH batteries is very useful, relevant to their recycling technology is also in active development.
