Highly efficient 3V cathodes for rechargeable sodium-ion batteries have been developed by users from Argonne National Laboratory's Materials Science, Chemical Sciences & Engineering, and X-ray Sciences Divisions, as well as the University of Chicago, together with the Center for Nanoscale Materials NanoBio Interfaces Group. With a near-theoretical capacity of 250 mAh/g, excellent rate capability and cycle life, and high energy and power densities of 760 Wh/kg and 1200 W/kg, respectively, these bilayered V2O5 systems can be used in applications at ambient temperature.
