Description
Technical Field
The utility model relates to the technical field of waste secondary battery treatment, in particular to a waste secondary battery dry smelting furnace.
Background
Lithium secondary batteries (Li-ion batteries) have been commercialized for the first time in 1991, and are beginning to be widely used in portable electronic devices, and are currently used to supply power to environmental-friendly next-generation electric vehicles. The demand for lithium secondary batteries is expected to grow rapidly due to the rapid expansion of the plug-in hybrid electric vehicle (PHEV), hybrid Electric Vehicle (HEV), and Electric Vehicle (EV) markets. This may lead to a natural disaster risk lithium metal resource supply. The global demand for lithium secondary batteries has been increasing explosively. Lithium secondary batteries contain rare metals such as nickel, cobalt, and manganese in addition to lithium. The demand for lithium carbonate (Li 2CO 3) is expected to increase from 26.5 ten thousand tons in 2015 to 49.8 ten thousand tons in 2025. Therefore, it is expected that lithium (Li) will come in short supply after 2023. Accordingly, many positive electrode manufacturers are currently developing new materials that replace lithium. Examples of materials that may replace lithium include sodium, aluminum, and vanadium. Although these materials are expected to replace lithium in secondary batteries in the future, the use amount of other components (e.g., nickel, cobalt, manganese) in secondary batteries is expected to increase rather than decrease. The demand for these rare metals is rapidly increasing, but the supply of raw materials is becoming more and more difficult. Thus, the need for recovery and recycling of these rare metals is expected to increase rapidly. Currently, hydrometallurgical processes are used to recover these rare metals. The hydrometallurgical process involves pre-treated leaching and selective precipitation to recover cathode materials, ion exchange and solvent extraction to extract valuable metals (solvent extraction), and additional purification and recovery techniques. Due to the high valence state of the positive electrode active material and the strong binding force of the organic binder, some hydrometallurgical processes have the disadvantages of relatively long leaching time and low leaching efficiency. In addition, a large amount of high-concentration acidic solution and reducing agent are used, the process steps are complex, a large amount of wastewater is generated, and secondary pollution is caused by the discharge of wastewater and harmful gas in the leaching process.
