A powdered sodium-ion battery offers 15 percent more energy density

“Our material also compares well with the class of layered materials for cathodes: It provides roughly the same battery capacity and greater stability, which translates into longer life and higher cost-efficiency of the battery,” Fedotov went on. “Remarkably, even the theoretical predictions for the competing materials fall short of the practical performance of ours, and this is far from trivial because the theoretical potential is never fully realized.”

With the proper research and development, the scientists hope their new batteries will be able to replace lithium-ion ones in heavy electric vehicles, such as buses & trucks, as well as in stationary energy storage at the wind, solar farms and elsewhere in all kinds of temperatures.

“Higher energy storage capacity is just one of the advantages of this material. It also enables the cathode to operate at lower ambient temperatures, which is particularly relevant for Russia,” Fedotov said.
