Et voilà deux articles qui tiennent la route sur la technologie.

L'intérieur de la batterie est à 900 degré Fahrenheit, soit 482 degré Celcius.
Chaud devant.
80 % de rendement.
Inside the box it's 900 degrees but outside it's cool to the touch. The system is about 80 percent efficient, but Giudice says very little energy is wasted.
"The inefficiency, that 20 percent of inefficiency, is actually given off as heat," Giudice says, "and that heat is held within the insulated box that holds the cells and that's sufficient to keep it at operating temperature, and you just charge and discharge to keep it at that state."

Sadoway’s battery is liquid-based and remains in that state as it operates at temperatures ranging from 400°C to 700°C. The essential components include a high-density liquid metal (bismuth today) at the bottom of the cell, a molten salt atop that, and a low-density liquid metal (lithium) above the salt. The two liquid metal layers serve as electrodes, while the molten salt acts as an electrolyte. The difference between the metals gives rise to the battery’s voltage.
The 1,000-cubic-foot version of the battery can store about 1 MWh of energy—about 250 kW with a four-hour drain time in many cells that are each about the size of a pizza box. Sadoway says a smaller version of the battery, roughly the size of a refrigerator, could eventually be marketed for energy storage in single-family homes

Les investisseurs :
........ During the first few years, Sadoway funded his basic research effort with backing from France-based Total Group and the US DOE’s Advanced Research Projects Agency-Energy. Eventually, however, he launched a private company, Ambri, Inc., using funding from a variety of private sources, including Total Group, Bill Gates, Khosla Ventures, and the Pritzker family.
