Our Process

  • The reverse logistics operation employs a HUB & SPOKE model, allowing us to acquire end-of-life Lithium-ion cells from a wide range of locations (SPOKE) and transport them securely and effectively to our main recycling facility (HUB).
  • Battery sources - We responsibly and ethically secure our inventory of used Li-ion cells from diverse sources, including electronics, electric vehicles, and other devices, with a steadfast commitment to safety. While our current procurement primarily focuses on India, we remain receptive to the potential of sourcing from international locations in the future.
  • Harnessing Technology - We employ cutting-edge technologies including Artificial Intelligence, Machine Learning, and Blockchain to continually enhance our efficiency, safety measures, raw material quality, and consistency.

Segregation and Dismantling process

Segregation and Dismantling process

  • Testing:
    1. Visual inspection:
      Batteries are visually inspected for any exterior damage or deformities.
    2. Voltage testing:
      Each battery is tested to measure its voltage output to check for any significant deviations.
  • Sorting:
    1. Sorting by type:
      Batteries are sorted based on their chemistry (e.g., lithium cobalt oxide, lithium iron phosphate) and form factor (e.g., cylindrical, prismatic).
  • Dismantling:
    1. Manual dismantling:
      Skilled technicians disassemble the batteries carefully, removing the outer casing and separating the internal components.

Mechanical process

  • Shredding: The batteries are fed into a shredding machine equipped with sharp blades that tear the batteries apart into smaller pieces. The shredded materials, which include electrodes, electrolytes, and casings, are collected for further processing.
  • Crushing: Secondary crushing: The shredded materials are further processed in a crushing machine to reduce their size into smaller fragments. In some cases, the crushed materials are further pulverized into fine powder to facilitate the separation of different components.
  • Separation of Components: Mechanical separation: Techniques such as sieving and magnetic separation are utilized to separate metal components (e.g., foils) from the powdered mix. Sieving: The fine powder is passed through sieves to separate the different components based on particle size.

Chemical Process

Chemical Process

  • Recovery of active materials: Processes such as hydrometallurgical or pyrometallurgical methods are employed to extract valuable metals such as cobalt, nickel, and lithium from the recovered materials.
  • Recovery of other components: Plastics and other non-metallic materials are also recovered for potential reuse or further recycling.

At PrithviCleantech, we are dedicated to reducing global mining pollution and minimizing battery waste in landfills. Through our commitment to achieving Net Zero Waste and Zero Emissions, we aim to produce high-quality battery materials at our Hubs.
