| Abstract |
Nowadays, with increasing hybrid electric vehicles, the amount of waste secondary batteries also increase dramatically. The waste secondary battery is considered as solid waste in many countries on account of the existence of hazardous components. Thus, it is necessary to recycle the waste secondary batteries through the proper way. The waste secondary battery is generally composed of cathode, anode, organic electrolyte and separator. Especially, valuable metals such as Co, Ni, Li and Mn are contained abundantly in cathode-active material and regarded as significant strategic metals in industry field. Therefore, many studies have been conducted on leaching of the metal species from cathode-active material by using inorganic acid such as HCl, HNO3, and H2SO4 as leaching agent. However, these acids could inevitably cause the corrosion and liquor waste. The present work aims at the recovery of each valuable metal from cathode-active materials in extraction and separation ways using environmentally acceptable various organic acids. |
