After two years of research, a French team, mostly including researchers from the CNRS and CEA within the RS2E network on electrochemical energy storage have just designed an alternative technology to Li-ion for application in specific sectors. The researchers have developed the first battery using sodium ions in the usual "18650" format, an industry standard. The main advantage of the prototype is that it relies on sodium, an element far more abundant and less costly than lithium. The batteries have displayed performance levels comparable to their lithium counterparts, and this new technology is already attracting industrial interest. It could be used to store renewable energies in the future.
