Georgia Tech team develops conversion-type iron-fluoride Li battery cathode with solid polymer electrolyte

Green Car Congress

Researchers at Georgia Tech have developed a promising new conversion-type cathode and electrolyte system that replaces expensive metals and traditional liquid electrolyte with lower cost transition metal fluorides and a solid polymer electrolyte. A paper on their work is published in the journal Nature Materials.

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.

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

Green Car Congress

The new material is a porous coordination polymer (PCP, also known as MOF; metal-organic framework), a framework consisting of zinc metal ions. However, weak gas-binding ability and/or poor sample crystallinity after guest exchange hindered the development of efficient materials for CO 2 incorporation, activation and conversion.

NSF awards $2M to Rice U collaboration to explore direct conversion of CO2 into fuels

Green Car Congress

We include experts in catalysts and electrolyzer design, polymer engineering, density functional theory simulations and carbon dioxide capture. We intend to build an electrochemical modular system as a platform for a continuous conversion process of simulated flue gas to pure liquid fuels. —Haotian Wang. —Haotian Wang.

LLNL 3-D printed biocatalytic polymer turns methane to methanol at room temperature and pressure

Green Car Congress

Methane monooxygenases (MMOs), found in methanotrophic bacteria, are selective catalysts for methane activation and conversion to methanol under mild conditions; however, these enzymes are not amenable to standard enzyme immobilization approaches. The enzymes retain up to 100% activity in the polymer construct. Blanchette et al.

Corvus Energy’s marine lithium polymer battery pack used in Europe’s first hybrid tugboat

Green Car Congress

Lithium polymer battery packs from Corvus Energy were recently installed in Europe’s first hybrid tugboat, the RotorTug RT Adriaan of KOTUG, an international maritime service provider headquartered in The Netherlands. The conversion features Corvus’ AT6500 48 volt lithium polymer battery packs. Corvus uses Dow Kokam cells.
