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.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

The shelf-life of stored charge in rechargeable devices does not scale linearly with maximum SP and has led to trends referred to as ‘range-anxiety’, ‘compulsive charging’, etc. The membrane allowed the batteries to function normally, but reduced charge loss to zero when the batteries were not in use.
