PNNL team develops electrolyte for high-voltage sodium-ion battery with extended longevity

Green Car Congress

Cheap and abundant, sodium is a promising candidate for new battery technology. However, the limited performance of sodium-ion batteries has hindered large-scale application. Sodium-ion batteries (NIBs) have attracted worldwide attention for next-generation energy storage systems. A paper on the work appears in Nature Energy.

BASF investigating sodium-air batteries as alternative to Li-air; patent application filed with USPTO

Green Car Congress

In a paper in Nature Materials , a team of researchers from BASF SE and Justus-Liebig-Universität Gießen report on the performance of a sodium-air (sodium superoxide) cell. Their work, they suggest, demonstrates that substitution of lithium by sodium may offer an unexpected route towards rechargeable metal–air batteries.

Researchers use multivalent cation additives to inhibit dendrite growth in rechargeable batteries

Green Car Congress

Researchers at Tohoku University have devised a means to stabilize lithium or sodium depositions in rechargeable batteries, helping keep their metallic structure intact. Multivalent cation additives modify the solvation structure of lithium or sodium cations in electrolytes and contribute to flat electrodeposition morphology.

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.

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.
