Dr. Udovic is recognized for the discovery of unparalleled superionic conduction in solid electrolyte materials suitable for rechargeable battery applications. He developed an entirely new class of sodium-based compounds that at high temperatures display ionic conductivities greater than those of any other known solid polycrystalline sodium-conducting materials. He further succeeded in reducing the temperatures at which the enhanced ionic conductivity occurs to technologically relevant temperatures, thereby making these materials prime candidates for commercially viable solid-state rechargeable batteries.
