High-voltage sodium-ion batteries with up to 15% higher energy density – pv magazine International

Researchers in Russia have developed a new sodium-vanadium phosphate fluoride powder. It has a particular crystal structure that provides superior energy storage capacity in the battery cathode. August 3, 2022 Marija MaischSodium-ion batteries continue to edge toward commercialization as a viable alternative to lithium-ion technology. And researchers from Russia’s Skolkovo Institute of Science and Technology (Skoltech) and Lomonosov Moscow State University have developed a new cathode material that promises higher energy storage capacity in sodium-ion batteries.They developed a powder of sodium-vanadium phosphate fluoride (NaVPO4F). It has a particular crystal structure that could ensure 10% to 15% higher energy density than current sodium-ion batteries.“Our material also compares well with the class of layered materials for cathodes. It provides roughly the same battery capacity…
