Abstract

Since the advent of high-technology is followed by industrialization, the amount of spent batteries used as power sources for mobiles, lap-tops, electric watches, remote controllers, and electric calculators are increasing. On the other hand, recovery processes for spent batteries have not been established systematically. In the whole world, approximately 300,000 tons of spent batteries are produced every year. Domestically, more than 12,000 tons of Mn batteries, 200 tons of primary Li batteries, 1,500 tons of secondary Li batteries are produced every year. However, most of spent batteries are buried in landfills or neglected.
Spent batteries are containing valuable metals such as Mn, Zn, Fe, Co, Ni and so on. Since South Korea depends on importing those valuable metals for industries and recycling of imported resources is highly demanded for the future. Therefore, recovery processes for spent batteries are necessary. In addition, KOH, NH4Cl, ZnCl2 and so on contained in spent batteries can cause land and water pollutions. Therefore, development of new recovery process for spent batteries is highly demanded.
Most of established recovery processes for spent batteries have categorization: crushing, classification, separation of valuable metals from dusts. However, those processes have serious problems with explosive crushing processes and emission of pollutive electrolytes. Also, classification is a time-consuming process and it makes processes inefficient.
This research is focused on developing recovery process for spent batteries to collect valuable metals without conventional processes such as classification, explosive crushing, and emission of pollutive electrolytes.
