Spanish scientists have created a battery made from sunflower husks for energy storage.

AgroReview reports Researchers from a Spanish university have presented the results of a new study that opens up the possibility of using sunflower husks for the production of eco-friendly batteries. The corresponding article was published in the Journal of Power Sources. New approaches to creating anodes for batteries As part of the study, Spanish scientists analyzed various types of biomass, including coffee grounds, plant residues, grape pits and peel, corn cobs, and compost. Sunflower husks turned out to be the most promising material for making anodes in sodium batteries. From the carbon materials obtained from it, it was possible to create anodes that maintain stability and withstand up to 1000 charge and discharge cycles without significant loss of energy capacity. Environmental benefits and prospects of sodium batteries Additionally, the team of scientists conducted a life cycle assessment of various material combinations to find the optimal balance between efficiency and ...
