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.

Researchers use melamine to create effective, low-cost carbon capture; potential tailpipe application

Green Car Congress

Using an inexpensive polymer called melamine, researchers from UC Berkeley, Texas A&M and Stanford have created a cheap, easy and energy-efficient way to capture carbon dioxide from smokestacks. The low cost of porous melamine means that the material could be deployed widely. Haiyan Mao 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.
