St. Andrews team elucidates behavior of carbon cathodes in Li-air batteries; the importance of the synergy between electrode and electrolyte

Green Car Congress

Carbon is seen as an attractive potential cathode material for aprotic (non-aqueous) Lithium-air batteries, which are themselves of great interest for applications such as in electric vehicles because of the cells’ high theoretical specific energy. Given the role of carbon as a possible porous positive electrode for nonaqueous Li?O

ARPA-E Selects 37 Projects for $106M in Funding in Second Round; Electrofuels, Better Batteries and Carbon Capture

Green Car Congress

This project seeks to combine the enzymes from a novel carbon fixation cycle in an extremophilic microbe termed an archaeon that grows optimally near 75°C with the hydrogen utilizing hydrogenase enzyme from another extremophilic archaeon to construct a hybrid enzymatic pathway. Batteries for Electrical Energy Storage in Transportation.

DOE awards $54M to 13 projects for transformational manufacturing technologies and materials; top two awards go to carbon fiber materials and electrodes for next-gen batteries

Green Car Congress

The top two awards, one of $9 million to a project led by Dow Chemical, and one of $8.999 million to a project led by PolyPlus, will fund projects tackling, respectively, the manufacturing of low-cost carbon fibers and the manufacturing of electrodes for ultra-high-energy-density lithium-sulfur, lithium-seawater and lithium-air batteries.
