US scientists at the Department of Energy’s Pacific Northwest National Laboratory (PNNL) have developed a new sodium battery technology:

“We showed that this new molten salt battery design has the potential to charge and discharge much faster than other conventional high-temperature sodium batteries, operate at a lower temperature, and maintain an excellent energy storage capacity,” said Guosheng Li, a materials scientist at PNNL and the principal investigator of the research. “We are getting similar performance with this new sodium-based chemistry at over 100 °C [212 °F] lower temperatures than commercially available high-temperature sodium battery technologies, while using a more Earth-abundant material.”
