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. An open-access paper on their work is published in the RSC journal Energy & Environmental Science. Wang et al.

Researchers show that inherent lithium ions in bioderived borate polymer enhance extreme fast charging capability in graphite anodes

Green Car Congress

Now, a study by a team of researchers, led by Professor Noriyoshi Matsumi from Japan Advanced Institute of Science and Technology (JAIST), showcases a new approach to facilitate fast charging using a binder material which promotes Li + -ion intercalation of active material. A paper on their work is published in ACS Materials Letters.

Li-ion sulfur polymer battery shows high energy density as well as safety

Green Car Congress

A team from the University of Rome Sapienza has developed a rechargeable lithium-ion polymer battery based on the combination of a high capacity sulfur-carbon cathode, nanostructured Li x Sn-C anode and polysulfide-added PEO-based gel membrane. Moreover, the addition of a dissolved polysulfide (i.e.

New porous coordination polymer captures CO2, converts it to useful organic materials

Green Car Congress

One possible way to counteract rising global CO 2 emissions is to capture and sequester carbon from the atmosphere, but current methods are highly energy intensive. The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions.

Self-healing polymer wrapper enables longer cycle life in silicon anodes for Li-ion batteries

Green Car Congress

Top: The stress of repeated swelling and shrinking shatters a conventional silicon electrode and its polymer binding. Bottom: An electrode coated with stretchy, self-healing polymer remains intact. (C. 1 for Li 15 Si 4 at room temperature)—almost ten times that of commercialized graphite anodes. Wang et al., Wang et al.
