ORNL team develops 3D interconnected polymer/ceramic composite as a thin film solid electrolyte

Green Car Congress

Oak Ridge National Laboratory researchers have developed a thin-film, highly conductive solid-state electrolyte made of a polymer and ceramic-based composite for lithium metal batteries. There are two classes of solid electrolytes, inorganic oxide- or sulfide-based electrolytes and polymer-based electrolytes. —Palmer et al.

Fraunhofer researchers develop new low-cost dry-film electrode production process

Green Car Congress

The new film transfer technology for dry electrode coating, on the other hand, operates without these ecologically damaging and expensive process steps: The IWS engineers mix their active material with binding polymers. The shear forces in this system tear entire molecular chains out of the binder polymers. 2019.05.033.
