A VALUABLE MATERIAL RECOVERY METHOD OF A SCRAPPED LITHIUM ION BATTERY

摘要

The present invention discloses a method for concentrating, recovering and recycling valuable metals contained in scraps of a lithium ion battery and a process of manufacturing lithium ion batteries having high added value by using a dry melting method, which is one of high temperature heat treatment methods. The present invention relates to a valuable metal recovery method of waste lithium ion battery, and to a method of recovering waste lithium ion battery and lithium ion battery through a simple pretreatment (crushing and crushing) process, including Ca ₂ based on SiO ₂ , MgO, and Al ₂ O _3. After mixing with the solvent, it is charged into a heating furnace and melted at a high temperature of 1,300 ° C to 1,700 ° C. The molten raw material is kept at 30 minutes to 3 hours under an oxygen partial pressure of 10 ^-17 atm or higher, and then naturally cooled. The main point of the configuration is that metal and impurities can be separated and recovered.;Waste Lithium Ion Battery, Melt Reduction, Valuable Metals, Recovery, Recycling
