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.

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.

A new study by Charles J. Using a new metric—“Energy Stored on Invested, ESOI”—they concluded that batteries were the worst performers, while compressed air energy storage (CAES) performed the best, followed by pumped hydro storage (PHS).

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

John Goodenough, known around the world for his pioneering work that led to the invention of the rechargeable lithium-ion battery, have devised a new strategy for a safe, low-cost, all-solid-state rechargeable sodium or lithium battery cell that has the required energy density and cycle life for a battery that powers an all-electric road vehicle.
