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

Xcel Energy has released the preliminary results from its wind-to-battery (W2B) storage project in Minnesota, and termed the technology successful. 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.

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.

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.

Mitsubishi and Tokyo Institute of Technology Developing EV Smart Charging from Wind Turbines

Green Car Congress

and the Tokyo Institute of Technology are developing a smart charging system to exploit wind power produced at night to charge electric vehicles. In order to store electricity generated at night, windmill operators need to install sodium-sulfur battery systems, which are as costly as power generators. Mitsubishi Corp.
