New long-duration, extended capacity Na-Al battery design for grid storage

Green Car Congress

Researchers led by the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have extended the capacity and duration of sodium-aluminum batteries. The new sodium-based molten salt battery uses two distinct reactions. of peak charge capacity. mAh cm −2 , a discharge duration of 28.2 —Weller et al.

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

Green Car Congress

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. We have proved that this technology can perform the functions of storage that we were looking for to help us manage the variability of wind energy on our operating system.

Energy storage: the key to a decarbonised future

Setec Powerr

We are transitioning from fossil fuels to renewable energy sources such as wind and solar, and the use of energy storage is becoming more widespread. And with the popularity of electric vehicles, the grid is under more and more pressure, so the demand for energy storage is growing. Battery storage.

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.

New high energy, highly stable cathode for sodium-ion batteries

Green Car Congress

Researchers in South Korea have developed a novel high-energy cathode material, Na 1.5 F 0.7 , for sodium-ion (Na-ion) batteries (NIBs). This new material provides an energy density of 600 Wh kg –1 , the highest value among Na-ion cathodes. In a prior study, they developed a new Li-ion battery electrode—Li 1.1

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 cell operates without a catalyst and has high storage efficiency. The present sodium-sulfur battery operates above 300 °C. V and charges at 4.2-4.4
