The cost of converting to a decarbonized economy is expected to be significantly reduced thanks to a new, low-cost battery that is four times as energy-dense as lithium-ion batteries and is produced at a much lower cost, according to an international team of researchers. The battery was developed under the direction of Dr. Shenlong Zhao from the University's School of Chemical and Biomolecular Engineering using sodium-sulphur, a type of molten salt that can be processed from sea water and is significantly less expensive to produce than lithium-ion. Sodium-sulfur (Na-S) batteries have been around for more than 50 years, but despite
