New solid-electrolyte interphase may boost prospects for rechargeable Li-metal batteries

Green Car Congress

In a paper in Nature Materials , the Penn State team reports a molecular-level SEI design using a reactive polymer composite, which effectively suppresses electrolyte consumption in the formation and maintenance of the SEI. In this project, we used a polymer composite to create a much better SEI. V Li|LiNi 0.5 Kim, Thomas E.

New cathode material for Li-S batteries: sulfur-anchored azulene

Green Car Congress

As described in an open-access paper in the RSC journal Chemical Communications ,the polymer exhibits high sulfur content and offers longer lifetime stability compared to pure sulfur, providing new protocols to develop new cathode materials for Li-S batteries. Cycling performance of Az-S and pure sulfur at 0.3 —Chen et al.

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

Green Car Congress

BroadBit uses it to produce new types of sodium-ion batteries. 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. They process this dry mixture in a rolling mill.
