Energy Storage System Powered by Forest Waste Retains 60% Capacity After 10,000 Cycles

Wedoany.com Report-Mar 9, In a study published in the Journal of Power Sources, researchers at the University of the Basque Country in Spain (UPV/EHU) presented an energy storage system made using electrodes derived from wood biomass.

Scientists in Spain found a way to use sawdust, which has a high carbon content, to make electrodes for energy storage

The wood biomass they used comes from a variety of pine tree, and it is widely available as a waste product from sawmills, making it both a cost-effective and sustainable method according to the Solid State and Materials Research Group at the UPV/EHU.

The group created the system using electrodes resulting from the discarded wood chips that they combined into a lithium-ion capacitor (LIC), a hybrid system combining batteries and supercapacitors. The negative electrode is made of hard carbon and achieves high capacity values of up to 112 mAh g⁻1 at 10C without complex doping procedures, the use of expensive additives or complex processing.
