High-voltage sodium-ion batteries are a necessity for low-cost batteries and electric vehicles. But they still have a way to go before they’re ready to replace the standard lithium-ion batteries that we see everywhere. Researchers are constantly looking for newer and better materials to fabricate sodium-ion batteries for greater stability and higher performance. 

Now, to make that search easier, researchers from RISE, TCG CREST have developed a new machine learning- and density functional theory-based model to predict the average voltage of novel materials. Published in Materials Today Physics, the paper identifies seven promising oxide and oxi-fluoro compounds with high average voltage that could serve as gamechangers for sodium-ion battery technologies. The modelling approach could further be used to investigate other materials and accelerate the development of sodium-ion batteries.
