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

Green Car Congress

Sodium is seen by some as a promising alternative, but the sodium-sulfur batteries currently in use run at temperatures above 300 °C, making them less energy efficient and safe than batteries that run at ambient temperatures. Sodium-ion batteries have been discussed in the literature. for some time. —Cao et al.

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. A final report is expected in summer 2011. The project is being conducted in Luverne, Minn., about 30 miles east of Sioux Falls, S.D.
