Argonne researchers find cathode material synthesis a key reason for performance degradation of sodium-ion batteries

Green Car Congress

One of the more promising candidates for batteries beyond the current standard of lithium-ion materials is the sodium-ion (Na-ion) battery. Na-ion is particularly attractive because of the greater abundance and lower cost of sodium compared with lithium. In addition, when cycled at high voltage (4.5

PG&E, Calif. Energy Commission launch 4MW sodium-sulfur grid storage pilot in San Jose

Green Car Congress

Pacific Gas and Electric Company (PG&E) and the California Energy Commission today unveiled a utility-scale sodium-sulfur battery energy storage system ( earlier post ) pilot project to better balance power needs of the electric grid. The system has a 4 megawatt capacity, and can store more than six hours of energy.

Stanford team develops sodium-ion battery with performance equivalent to Li-ion, but at much lower cost

Green Car Congress

Stanford researchers have developed a sodium-ion battery (SIB) that can store the same amount of energy as a state-of-the-art lithium ion, at substantially lower cost. Thus, further research is required to find better sodium host materials. Thus, further research is required to find better sodium host materials.

Xcel Terms First Phase of Sodium-Sulfur Battery Wind Energy Storage Test Project Successful

Green Car Congress

In October 2008, Xcel began testing a one-megawatt sodium-sulfur (NaS) battery ( earlier post ) to demonstrate its ability to store wind energy and move it to the electricity grid when needed. Support the transmission grid system by providing voltage support, which contributes to system reliability.

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

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. The high energy storage has stimulated a worldwide study of Li-air batteries. V and charges at 4.2-4.4

Molten-Salt Battery Freezes Energy Over a Whole Season

Cars That Think

As the pressure to decarbonize electricity grids mounts, so does the need to have long-term storage options for power generated from renewables. While rechargeable batteries are the solution of choice for consumer-level use, they are impractical for grid-scale consideration. When it comes to potential applications, adds Vincent L.
