This is reported by AgroReview Researchers from a university in Spain have presented the results of a new study that opens up the possibility of using sunflower husks for the production of environmentally friendly batteries. The corresponding article has been 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 waste, grape seeds and skins, corn cobs, and compost. Sunflower husks turned out to be the most promising material for making anodes in sodium batteries. Carbon materials obtained from it were able 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 ...
