Researchers have developed a new type of material that could make sodium batteries more efficient.
Developed by an international team of interdisciplinary researchers, including the Canepa Research Laboratory at the University of Houston, the material could boost the energy performance of sodium batteries, paving the way for a more sustainable and affordable energy future.
Researchers have highlighted that the new material, sodium vanadium phosphate with the chemical formula NaxV2(PO4)3, improves sodium-ion battery performance by increasing the energy density—the amount of energy stored per kilogram—by more than 15%.
With a higher energy density of 458 watt-hours per kilogram (Wh/kg) compared to the 396 Wh/kg in older sodium-ion batteries, this material brings sodium technology closer to competing with lithium-ion batteries.
