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.

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. Sodium-Silica-Gel: 2Na-SG + H 2 O → H 2 + Na 2 Si 2 O 5.
