Lignin-derived biochar is a game changer in terms of its potential applications in lithium-ion batteries (LIBs), particularly as a conductive electrode additive and active lithium host material.

The biochar has been found to exhibit high conductivity similar to Super P carbon black, the main conducting material found in most batteries. What’s more, biochar only creates 1.2 kg of CO2 per kg while Carbon black creates 2.4kg of CO2 per kg, a reduction in greenhouse gases of 50%.

Studies suggest that replacing carbon black with biochar can significantly enhance the sustainability of LIBs, with real potential to revolutionize the lithium-ion battery industry and make it much more sustainable than it is today.

Key Points

  • Biochar can be an effective conductive additive in LIB anodes with graphite, showcasing improved cell efficiency and rate capability comparable to Super P Carbon Black.
  • Biochar creates 50% less greenhouse gases during production as compared to Super P Carbon Black
