Biochar Powers the Future: How Corncobs Are Upcycled into Battery Catalysts

Turning agricultural waste into a high-performance energy solution? Cutting-edge research reveals its potential! 

A innovative research has successfully transformed corncobs into a high-performance biochar electrocatalyst through a process of pyrolysis and chemical activation. In Zinc-Air battery tests, this material demonstrated impressive results:

  • Exhibits excellent bifunctional catalytic activity (ORR & OER).
  •  Achieves an open-circuit voltage of ~1.4V.
  •  Delivers a max power density of 55 mW cm⁻².

This breakthrough paves a new path for upcycling biomass waste, offering a low-cost and sustainable catalyst for future energy storage.  The future of biochar in sustainable energy is bright!
