Japanese researchers succeed in extracting rare metal from lithium-ion batteries
The current lithium-ion battery recycling system includes the usage of toxic inorganic acids such as sulfuric acid or strong organic solvent which are very harmful to the environment. In addition, some chemical process includes high-temperature condition and emit toxic corrosive vapors which is very dangerous to factory operators.
Researchers all over the world work on improving the recycling of lithium-ion batteries. Now Dr. Ryohei Mori at Green Science Alliance developed alternative process to extract and recycle rare metals from lithium-ion battery cathode materials. He has also succeeded in extracting cobalt, nickel and manganese from the waste material called “Black Mass” from lithium-ion batteries. His solution: Instead of using toxic inorganic acid and solvent, he uses the so-called deep eutectic solvent.
