Recycling of Spent Batteries
Recycling of Spent Batteries from Electric Drive Vehicles
TMEC’s top-engineers, as a part of a NMetAU team, successfully completed the R&D GIPP project BNL-T2-0372-UA “Recycling of Spent Batteries from Electric Drive Vehicles” launched by the U.S. Department of Energy and Brookhaven National Laboratory with the main task to develop a unique, energy-efficient high-temperature furnace technology for thermal treatment of carbon materials recovered from used lithium-ion batteries.
The developed technology allows to remove such impurities as metals, organics, residual sulphur and other contaminants at 2000-2500°C in electro-thermal fluidized bed. To put this technology to practice, the project team developed a number of successive technological operations and the appropriate equipment ensuring the efficiency of the whole process and high quality of the finished product. The operations include: preliminary drying; storing and feeding the material into the furnace; material treatment and cooling.
The main results of the project are:
- the operating prototype of the small technological line (10 kg/hr) which was intended to test a number of design solutions and check technologies of treatment modes.
- the industrial equipment comprising a furnace (1000 kg/hr) with electro-thermal bed, product coolers, auger feeders, an after-burner, a cyclone and a dryer.
