AI insight
AI-generatedThe innovation is at lab/prototype stage with no commercial scale or timeline specified. The commercial mechanism is weak: potential future benefit for fuel cell manufacturers and battery recyclers, but no immediate revenue, cost, or supply impact. Sectors selected reflect the technology's relevance to renewable energy (fuel cells), industrial materials (graphite processing), and mining (graphite supply).

- Spent graphite from lithium-ion batteries repurposed to improve methanol fuel cell efficiency.
- Exfoliated spent graphite captures leaking methanol, preventing platinum catalyst poisoning.
- Fuel cell lifespan extended from ~15,000 cycles to 20,000-25,000 cycles.
- Prototype under development after successful lab validation.
- Research led by Prof Raman Vedarajan at Advanced Research Centre for Powder Metallurgy and New Materials.
