DOE awards $54M to 13 projects for transformational manufacturing technologies and materials; top two awards go to carbon fiber materials and electrodes for next-gen batteries

Green Car Congress

The top two awards, one of $9 million to a project led by Dow Chemical, and one of $8.999 million to a project led by PolyPlus, will fund projects tackling, respectively, the manufacturing of low-cost carbon fibers and the manufacturing of electrodes for ultra-high-energy-density lithium-sulfur, lithium-seawater and lithium-air batteries.
