Sulfur-ion Batteries to be Cheaper, More Energy Dense

A new type of battery that both lithium and sulfur ions is currently being developed at the DOE’s Oak Ridge National Laboratory, and it promises to outwit, outplay, and outlast the best batteries currently on the market, for a fraction of the cost. How big of a boost does sulfur give “conventional” lithium-ions? The lab’s researchers are reporting that their sulfur ion batteries have approximately four times the energy density of the lithium-ion batteries currently found in electric cars like the Nissan Leaf and Tesla Model S.
