Westborough, Massachusetts, United States

● Worked in a team of highly skilled metallurgists and battery scientists; applied hydrometallurgical techniques on mixed metal hydroxide precipitates to selectively remove impurities like magnesium, iron and aluminium with the end goal being obtaining high purity battery grade Cathode active material(CAM)(98%) for high performance applications and eliminating waste from end of life Lithium ion batteries.● Extended support to other research teams; worked on Lithium pilot plant by using… Show more ● Worked in a team of highly skilled metallurgists and battery scientists; applied hydrometallurgical techniques on mixed metal hydroxide precipitates to selectively remove impurities like magnesium, iron and aluminium with the end goal being obtaining high purity battery grade Cathode active material(CAM)(98%) for high performance applications and eliminating waste from end of life Lithium ion batteries.● Extended support to other research teams; worked on Lithium pilot plant by using pyrometallurgical techniques like roasting black mass for technical grade Lithium carbonate recovery. ● Achieved 17.6% cumulative Mg removal from black mass using flotation techniques; also gained some knowledge on ICP-OES●Equipment setup and configuration, SOP writing and managing and multifunctional role in a startup were some additional learning opportunities.

● Determined and estimated ratio of slurry compositions for different ambient condition parameters: temperature, humidity● Figured out a mass balance on the process and found about 5-7% by weight of scrap could be reused and mixed with raw materials thereby eliminating waste and making the process more sustainable.● Provided new boiler specifications by changing the tube design and thereby optimizing heat transfer. Hypothesised that this will help lower fuel consumptions by 7.8%… Show more ● Determined and estimated ratio of slurry compositions for different ambient condition parameters: temperature, humidity● Figured out a mass balance on the process and found about 5-7% by weight of scrap could be reused and mixed with raw materials thereby eliminating waste and making the process more sustainable.● Provided new boiler specifications by changing the tube design and thereby optimizing heat transfer.

Nagpur, Maharashtra, India

● Verified process flowcharts and unit operations(filtration, drying, mixing) in order to make sure that they were efficient and safe● Conducted studies to find accuracy of packaging: Reported about 2% (w/w) foreign materials were present in a batch during packaging● Inspected nitrogen and carbon dioxide levels (ensured MAP levels) and integrity of packaging by initiating random checks
