PNNL team develops sodium-manganese oxide electrodes for sodium-ion rechargeable batteries

Green Car Congress

The resulting improved electrical capacity and recharging lifetime of the nanowires. Lithium-ion rechargeable batteries perform well, but are too expensive for widespread use on the grid. Sodium-ion batteries have been discussed in the literature. makes them a promising candidate to construct a viable and. for some time.

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.

New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

Rechargeable lithium metal batteries with increased energy density, performance, and safety may be possible with a newly-developed, solid-electrolyte interphase (SEI), according to Penn State researchers. The same approach was also applied to design stable SEI layers for sodium and zinc anodes. Credit: Donghai Wang,Penn State.

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.
