UT Austin team identifies promising new cathode material for sodium-ion batteries: eldfellite

Green Car Congress

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. Sodium-ion intercalation batteries—i.e., However, sodium-ion batteries face issues related to performance, weight and instability of materials.

SiGNa Chemistry Demonstrates Sodium Silicate-Based Hydrogen Generation System for Portable Fuel Cells

Green Car Congress

Prototype sodium silicate hydrogen generation system as presented earlier this year at DOE merit review. The H300 utilizes real-time swappable cartridges that generate hydrogen on demand using SiGNa’s proprietary sodium silicide (NaSi) powder. At greater than 9% hydrogen by weight, sodium silicide technology produces comparable results to chemical hydride technologies such as ammonia borane or sodium borohydride.

Univ. of Texas researchers propose lithium- or sodium-water batteries as next generation of high-capacity battery technology; applicable for EVs and grid storage

Green Car Congress

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. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. Also, sodium rather than lithium might be used as the anode.
