In recent years the lithium consumption for batteries has remarkably increased because of the extensive applications of rechargeable lithium batteries in portable electronic devices, electric tools, electric vehicles, and grid storage. The surging demand for these applications asks for innovative solutions for recycling of the spent lithium ion batteries. This proposed project is an attempt to develop solutions for two of the challenges in the lithium ion battery recycling process flowsheet of a Canadian company, Li-Cycle, to produce high value products for market from the ingredients of spent batteries.
