Second Life for Lithium: How LIBS Enhances the Recycling Process

The age of sustainable energy and eco-friendly solutions has ushered in an unprecedented demand for lithium-ion batteries. From powering our smartphones to our electric cars, these batteries have undoubtedly become an integral part of our daily lives. But as our last article in the lithium series highlights, there’s one critical question we need to address: What happens to these batteries when they reach the end of their lifespan?

Challenges of Lithium recycling

Recycling lithium is far from straightforward. While an impressive 95% of a lithium-ion battery can be repurposed into new batteries, the economic challenges of recycling are substantial. One of the primary obstacles is the low value of the retrieved materials. Though these batteries contain metals like lithium, cobalt, and nickel, market prices often don’t support recycling’s costs, especially for lithium and cobalt, which are obtained in minor amounts. Further complicating matters is the lack of a standardized recycling process. Given the various chemistries and designs of Li-ion batteries, each demands a unique recycling method. This diversity hinders economies of scale, leading to inflated costs.

The primary incentive to recycle batteries arises from the scarcity of lithium. But it’s not just about this element. Batteries encompass other materials, including precious metals. Regrettably, the recycling process for these materials is inefficient. A substantial portion of these materials vanishes – burned or evaporated – during the process, leaving a vast potential untapped.

Black Mass

Lithium-ion batteries, once retired, are a goldmine of metals like lithium, copper, and cobalt. After collection, these batteries are shredded, and the base metals separated, predominantly by ‘shredders’. The resultant compound, termed ‘black mass‘, is a rich repository of the metals from battery anodes and cathodes. Dominated by the graphite from the anodes, this substance constitutes 40-50% of an EV battery’s weight. The next phase sees recyclers diving into this mass, extracting and repurposing the metals, offering a fresh lease of life to the battery metal ecosystem.

How can LIBS help in the recycling process?

When it comes to addressing the intricacies of lithium battery recycling, LIBS, or Laser-Induced Breakdown Spectroscopy, stands out as a transformative solution. Let’s unpack its groundbreaking features:

  1. Elemental Identification: LIBS excels in detecting and quantifying light elements with remarkable accuracy. Key elements of batteries, such as lithium, cobalt, manganese, and nickel, fall right within its expertise.
  1. Purity Verification: LIBS can provide real-time analysis of chemical purity, ensuring that the extracted lithium oxide adheres to strict purity standards, essential for top-tier battery production.
  1. Speed and Integration: LIBS provides rapid and accurate chemical assessments, facilitating its seamless integration into recycling processes and enhancing overall efficiency.
  1. Economic Benefit: By enhancing the precision and speed of the recycling process, LIBS significantly boosts the economic viability of lithium recycling. When more elements are accurately recovered, and contaminants are minimized, the return on investment for recycling plants rises.

As we’ve seen, the story of lithium doesn’t end when a battery depletes; with precision and innovation, its lifecycle can be both extended and optimized. In concluding our comprehensive series on lithium, it becomes clear how integrated processes and technologies, like LIBS, play pivotal roles in every phase of lithium’s journey. From its extraction to its various applications and eventual recycling, LIBS stands out as a revolutionary method, enhancing speed, driving efficiency, and ultimately reducing costs across the board.
