In STREAMS, ISPE will lead tasks 3.1 (Work Package 3) of and 4.1 (Work Package 4) by performing electrowinning to recover metal ions from the secondary sources and recycled black mass. ISPE will also prepare LFP from recycled black mass and will assist AETC in the production of Si/C anodes composites (Work Package 5).
Meet the faces behind the project
Viacheslav Barsukov is the Project Manager and leading scientist of the ISPE research team with a special emphasis on electrowinning methods.
After dissolving the ferrous mass in sulphuric acid, we obtain a mixture of nickel, cobalt, manganese and lithium sulphates in aqueous solution, which we subject to electrolysis. This produces a pure ferromagnetic nickel-cobalt alloy at the cathode (Fig.1) and a pure electrolytic manganese dioxide powder at the anode (Fig.2). Both of these products can have both independent commercial use and be used as raw materials for the STREAMS project (task 4.1). The degree of ion extraction is now as follows: nickel – 57%, cobalt – 98.2%, and manganese – 98.6% according to the results of atomic adsorption analysis.
About ISPE
Founded in January 1991, the Institute of Sorption and Endoecology Problems (ISPE) is a leading research institution in the synthesis, study and practical application of specialised carbon, inorganic, composite sorbents and catalysts. The Institute’s assets include inorganic ionites for deep purification of complex solutions from heavy metals and a wide range of radionuclides; biosorption composite sorbents for soil purification from pesticides; selective catalysts for processing renewable raw materials and new catalytic processes; new carbon electrode materials for supercapacitors and their hybrids with batteries. A number of the Institute’s developments are aimed at strengthening the defense capabilities of our country.
