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.

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

Green Car Congress

The binder material—a novel aqueous borate type bio-based polymer with inherent Li + ions designed as an SEI forming binder for graphite—leads to improved diffusion of desolvated Li + ions across the solid electrolyte interface (SEI) and within the anode material and yields high conductivity, low impedance, and good stability.

Researchers show coordination polymer glass membranes can produce as much energy as liquid-based counterparts in fuel cells

Green Car Congress

Scientists at Kyoto University’s Institute for Integrated Cell-Material Sciences (iCeMS) have developed a new coordination polymer glass membrane for hydrogen fuel cells that works just as well as its liquid counterparts with added strength and flexibility. Adding zinc to this liquid led to the formation of a solid, elastic polymer glass.

Polymer-based membranes offer alternative to thermal processes for separating hydrocarbon and crude oil mixtures

Green Car Congress

Polymer-based membranes developed at KAUST could enable greener and cheaper industrial separation approaches. Polymer membranes are cheaper and easier to manufacture and adapt to large-scale processes than inorganic membranes. A paper on the work is published in Science.

Stanford engineers develop catalyst strategy to improve turnover frequencies for CO2 conversion to hydrocarbons by orders of magnitude

Green Car Congress

Researchers at Stanford University have shown that porous polymer encapsulation of metal-supported catalysts can drive the selectivity of CO 2 conversion to hydrocarbons. The research team encapsulated a supported Ru/TiO 2 catalyst within the polymer layers of an imine-based porous organic polymer that controls its selectivity.

Global Bioenergies’ bio?isobutene now at 99.77% purity; polymer-grade level

Green Car Congress

Global Bioenergies has purified its bio‐isobutene to 99.77%, a polymer‐grade level. Several applications in the polymers business (rubbers, plastics.) require high‐purity isobutene, and 99.77% corresponds to the polymer‐grade standard.
