Since 1986, Goodenough has been a Professor at The University of Texas at Austin in the Cockrell School of Engineering departments of Mechanical Engineering and Electrical Engineering. During his tenure there, he has continued his research on ionic conducting solids and electrochemical devices; he stated that he continued to study improved materials for batteries to help promote the development of electric vehicles and help reduce the dependency on fossil fuels. Arumugam Manthiram and Goodenough discovered the polyanion class of cathodes. They showed that positive electrodes containing polyanions, e.g., sulfates, produce higher voltages than oxides due to the inductive effect of the polyanion. The polyanion class includes materials such as lithium-iron phosphates that are used for smaller devices like power tools. His group has also identified various promising electrode and electrolyte materials for solid oxide fuel cells. He currently holds the Virginia H. Cockrell Centennial Chair in Engineering.
