Sawdust superpower: Wood waste batteries

Friday 7 Mar 2025

Researchers at the University of the Basque Country (UPV/EHU) have developed a hybrid supercapacitor using carbon derived from Pinus radiata waste. The lithium-ion capacitor features electrodes made from discarded wood particles, offering a sustainable and cost-effective energy storage solution.

With abundant biomass resources in the Basque Country in Spain, the team utilised environmentally friendly and inexpensive processes to create high-performance electrodes. Their findings highlight the potential of biomass-based materials in producing efficient, eco-friendly energy storage systems.

The UPV/EHU team developed a cost-effective LIC using carbon from Pinus radiata waste, an abundant and sustainable resource in Biscay, Spain. They produced high-performance electrodes using carbon sourced from biomass instead of costly chemicals or energy-intensive procedures. According to researchers, the innovation could pave the way for greener alternatives in high-power energy storage, reducing reliance on conventional materials and enhancing sustainability in the sector.
