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. The sodium salt makes up the cathode; the anode is made up of phosphorous.

New liquid alloy electrode significantly lowers operating temperature of sodium-beta batteries; improved performance

Green Car Congress

Researchers at Pacific Northwest National Laboratory (PNNL) have devised an alloying strategy that enables sodium-beta batteries to operate at significantly lower temperatures. The new electrode enables sodium-beta batteries to last longer, helps streamline their manufacturing process and reduces the risk of accidental fire.

Iowa State/Ames Lab researcher receives $3M from ARPA-E for solid-state sodium battery

Green Car Congress

The Advanced Research Projects Agency - Energy (ARPA-E) has awarded $3 million from its 2015 OPEN funding to a project to develop an all-solid-state sodium battery. A sodium-based battery, on the other hand, has the potential to store larger amounts of electrical energy at a significantly lower cost. Led by Steve W.

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. Results also indicate that this technology may be applicable for solar energy. They are able to store about 7.2

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. A = lithium or sodium (Li or Na), M represents a metal and 1 ≤ n < z. —Lu et al.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

The best-known wearable energy-harvesting tech today is, of course, solar, which pulls down electrons from sunlight or ambient light. But solar is just the opening gambit. A backpack with a giant solar panel might work technically, but not in reality. volts for about 60 hours. Leveraging watch tech for…bisons?

Total Signs Research Agreement with MIT to Develop New Stationary Batteries for Solar Power; Smaller-Scale Version of All-Liquid Metal Battery Work Supported by ARPA-E

Green Car Congress

Total has signed a research agreement with the Massachusetts Institute of Technology (MIT) to develop new stationary batteries that are designed to enable the storage of solar power. This new class of batteries could enable continuous power supply from renewable energy sources, such as wind and solar and a more stable, reliable grid.
