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 utilized 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.
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. […]
In the new configuration, the positive electrode, which is composed of the same carbon, has a big surface area, while the negative electrode stores a lot of energy without the need for expensive chemicals. The system provides 105 Wh/kg at 700 W/kg and retains 60 percent capacity after 10,000 charge cycles.
The study points to the potential of local biomass as a cost-effective, eco-friendly alternative for lithium-ion capacitors. The team highlights that biomass-derived materials offer promising opportunities for high-power energy storage, emphasizing the need for continued research to improve energy storage technologies with sustainable solutions.
