KIST develops new batteries 40% cheaper, stronger than lithium-ion batteries
Apr 19, 2021
The Korea Institute of Science and Technology on Monday said it has developed sodium-ion batteries that are 40 percent cheaper and can store 1.5 times more charge per gram than conventional lithium-ion batteries. The batteries use sodium instead of lithium. As sodium is far more common than lithium -- it’s in regular salt -- this brings down the price significantly. However, sodium ions are bigger and heavier than lithium ions, so existing anode materials -- made of graphite and a small
