Chalmers team develops graphite-like anode for Na-ion batteries; Janus graphene

Green Car Congress

Researchers at Chalmers University of Technology, Sweden, have developed a nanometric graphite-like anode for sodium ion (Na + storage), formed by stacked graphene sheets functionalized only on one side, termed Janus graphene. The estimated sodium storage up to C 6.9 Na is comparable to graphite for standard lithium ion batteries.

Expanded graphite as a superior anode for sodium-ion batteries

Green Car Congress

Researchers at the University of Maryland, with colleagues at the University of Illinois at Chicago, report on a new method for expanding graphite for use as a superior anode for sodium-ion batteries in a paper in Nature Communications. Galvanostatic studies showed that expanded graphite can deliver a high reversible capacity of 284?mAh?g

Study shows biodiesel blends in buses reduce PM, other harmful exhaust elements, EC and CO

Green Car Congress

A new study on the combustion properties of biodiesel for use in urban transit buses found that using biodiesel can effectively reduce the mass of particulate matter released in both hot and cold idle modes. In sum, they recommended that governments consider using blends of biodiesel in urban and commercial vehicles to enhance air quality.
