The DRYtraec coating process developed at the Fraunhofer Institute for Material and Beam Technology IWS allows the dry production of battery electrodes without toxic organic solvents or water ( earlier post ). They coat electrodes for lithium-ion, solid-state or lithium-sulfur batteries continuously and scalable in a roll-to-roll process.

Li-S cells have five times the theoretical maximum specific energy of Lithium-ion cells. The mass density of Lithium Sulfur cells is very similar to that of water. As a result, bulky and expensive buoyancy foam is not required for the Lithium Sulfur battery as it is with Lithium Polymer batteries in use today.

The carbons simultaneously exhibit electrical conductivity more than 3x more than activated carbons; very high electrochemical activity at high mass loading; and high stability, as demonstrated by supercapacitors and lithium–sulfur batteries with excellent performance. Tests were also conducted on lithium-sulfur batteries.

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.
