New class of coordination polymers for high-performance Li-, Na- and K-ion storage

Green Car Congress

Researchers at the Université catholique de Louvain in Belgium have designed and synthesized a new class of electrically conducting anionic coordination polymers for all practically relevant alkali-cation storage. V in lithium-, sodium-, or potassium-based cells. Wang et al. doi: 10.1039/D2EE00566B.

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.

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. In order to protect operators and the environment, elaborate precautions for occupational safety and reprocessing are necessary. The shear forces in this system tear entire molecular chains out of the binder polymers. They process this dry mixture in a rolling mill.

UT Austin team devises new strategy for safe, low-cost, all-solid-state rechargeable Na or Li batteries suited for EVs

Green Car Congress

John Goodenough, known around the world for his pioneering work that led to the invention of the rechargeable lithium-ion battery, have devised a new strategy for a safe, low-cost, all-solid-state rechargeable sodium or lithium battery cell that has the required energy density and cycle life for a battery that powers an all-electric road vehicle.

Energy Harvesting for Wearable Technology Steps Up

Cars That Think

Solar won’t work for nocturnal animals or creatures in low-light environments. Challenges: Sustainability and industry collaboration This efficient energy harvester combines piezoelectric composites with carbon fiber–reinforced polymer and epoxy resin, a unique combination that was able to store electricity even after 100,000 uses.

OSU smart membrane could enable new category of high-energy, high-power energy storage for EVs

Green Car Congress

Applying an electrical potential to the conducting polymer membrane alters the redox state, allows it to conduct ions across the membrane. The team reported a maximum conductance of 30 µS cm -1 and a current gain of 60x as the polymer switches between oxidized and reduced states. Travis Herya and Sundaresan (2016).
