“Lithium-ion batteries today are reaching their theoretical energy limits. To overcome these limits, my team works on next-generation sodium-, magnesium- and aluminum-ion batteries, which can offer higher energy density and/or lower cost due to the different material chemistries. For example, a magnesium ion carries twice the charge of a lithium ion, which means that a magnesium battery has twice the charge capacity of its lithium counterpart and can last twice as long on a single charge. By combining experiment and theory, we design novel battery materials (cathode, anode, electrolyte), understand structure-property relationships, and construct battery prototypes. These advanced batteries can be used to power both stationary and electromobile applications for a sustainable energy future.”
