New Liquid Alloy Electrode Improves Sodium-beta Battery Performance

August 2014

PNNL, with funding from the DOE Office of Electricity Delivery and Energy Reliability, has developed a new material that could allow more utilities to store large amounts of renewable energy and make the nation's power system more reliable and resilient. The liquid metal alloy is used in an electrode that enables sodium-beta batteries to operate at significantly lower temperatures, which extends battery life, helps streamline the manufacturing process and reduces the risk of accidental fire.

The team is now building a larger electrode to test with a larger battery, bringing the technology closer to the scale needed in order to store renewable energy. To learn more about the new liquid alloy electrode, read the PNNL news release.
