Li-ion Battery Recycling Technology

Li-ion Battery Recycling Technology:

The Ministry of Electronics and Information Technology (MeitY) in India has transferred cost-effective lithium-ion battery recycling technology to nine recycling industries and start-ups as part of the Mission LiFE under the “Promote circularity campaign.”

  • This indigenous technology can process various types of discarded lithium-ion batteries, recovering over 95% of lithium, cobalt, manganese, and nickel contents in the form of corresponding oxides/carbonates with a purity of about 98%.
  • The recycling process of lithium-ion batteries involves several steps.
    • First, the batteries are collected, sorted and disassembled
    • Next, the electrodes, which contain valuable metals like lithium, cobalt, manganese, and nickel, are extracted, through a process called leaching, where the electrodes are submerged in a liquid that dissolves these metals.
    • After that, the metals are purified to remove impurities, resulting in high-purity lithium, cobalt, manganese, and nickel compounds.
  • Aim is to recover valuable materials from lithium-ion batteries, reducing the need for mining and minimizing environmental impact.
  • It helps conserve resources and promotes sustainable practices in battery manufacturing.
  • Developed by the technology was developed at the Centre of Excellence on E-waste Management, in collaboration with the Government of Telangana and industry partner.
