Recycling Lithium-ion Batteries – Green Technology and Circular Economy

GS 3 – SCIENCE AND TECHNOLOGY

Context:

Arvind Bhardwaj, co-founder and CTO of MiniMines Cleantech Solutions, highlights the importance of recycling lithium-ion batteries (LIBs) to address environmental and resource sustainability challenges. With the increasing demand for electric vehicles (EVs) and clean energy solutions, efficient battery recycling is becoming crucial.

Key Highlights

1. Environmental Concerns:
   • Lithium-ion batteries contain heavy metals that pose serious environmental risks if improperly disposed of.
   • Improper handling can lead to fire hazards, soil contamination, and health risks.
2. MiniMines’ Contribution:
   • Developed a proprietary Hybrid Hydrometallurgy process to:
     • Recover high-purity nickel, lithium, cobalt, graphite, and copper from all types of end-of-life batteries.
     • Reduce mineral import dependence and support a circular economy.
   • Achieved high recovery rates:
     • Nickel: 96%
     • Purity: 99%
3. Global Context:
   • With the rise of electric vehicles and renewable energy storage, global demand for LIBs is skyrocketing.
   • Sustainable recycling of LIBs ensures resource security and minimizes environmental damage.
4. Circular Economy Impact:
   • By recycling LIBs, India can reduce dependence on imported raw materials.
   • Strengthens India’s energy security and creates pathways for green job opportunities.
5. Challenges:
   • Limited infrastructure and high costs of recycling technology.
   • Need for government policies to support domestic battery recycling ecosystems.
