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.

DOE awards Cummins $5M for automation of electrolyzer cell and stack assembly

Green Car Congress

Rapid innovation like this will drive the acceleration of the energy transition in the United States and globally. Proton exchange membrane (PEM) electrolyzers use a solid polymer electrolyte, and alkaline electrolyzers use an electrolyte solution, such as potassium hydroxide or sodium hydroxide mixed with water.
