Professor John Goodenough, the inventor of the lithium-ion battery, and his team at the University of Texas at Austin have identified a new cathode material made of the nontoxic and inexpensive mineral eldfellite (NaFe(SO 4 ) 2 ), presenting a significant advancement in the quest for a commercially viable sodium-ion battery.

Example of a lithium-water rechargeable battery. Researchers at the University of Texas, including Dr. John Goodenough, are proposing a strategy for high-capacity next-generation alkali (lithium or sodium)-ion batteries using water-soluble redox couples as the cathode. The present sodium-sulfur battery operates above 300 °C.
