Efforts to commercialize light-weight, energy-dense lithium-sulfur secondary batteries (2510 Wh kg –1 ) have been stalled by ongoing problems with the battery’s membrane, which limits cycle-life. Sepion’s polymer membrane technology provides a counterpoint, yielding long-lasting lithium-sulfur cells.

DOE recognizes that technology developments can help make vehicles more efficient and alternative fuels more economic, but the deployment of any technologies it helps develop is largely determined by policies, such as Corporate Average Fuel Economy standards. Near-term improvements will likely be the result of improved lithium-ion batteries.
