Progress On the Ultimate Battery
November 3, 2015 | Leave a Comment
University of Cambridge scientists have developed a working laboratory demonstrator of a lithium-oxygen battery which has very high energy density, is more than 90% efficient, and, to date, can be recharged more than 2000 times. Also known as a lithium air battery the Cambridge team has made major progress in the field. Lithium-oxygen, or lithium-air, […]

Using Graphene to Convert Heat to Electricity
August 25, 2015 | 1 Comment
Professor Ian Kinloch, Professor of Material Science at the University of Manchester added a small amount of graphene to strontium titanium oxide. The resulting composite thermoelectric material was able to convert heat which would otherwise be lost as waste into an electric current over a broad temperature range, all the way down to room temperature. […]

A researcher team at MIT led by professors Evelyn Wang and Jing Kong, has developed a way of coating copper with graphene. An important use would be condensing steam back to water. A thin coating on copper condensers could make power plants more efficient, the MIT scientists report. Most of the world’s electricity-producing power plants […]

Molybdenum Disulfide Joins Graphene As a Wonder Material
November 18, 2014 | Leave a Comment
Northwestern University scientists are working to isolate atomically thin layers of molybdenum disulfide. Thinned down molybdenum disulfide has immediate and obvious applications in electronics, optoelectronics, solar cells, and catalysis. Atom thick sheets of material got researchers rolling when graphene was first produced in the lab in 2004. Literally thousands of laboratories began developing graphene products […]

Sodium Ion Battery Technology Takes A New Leap Forward
January 30, 2014 | Leave a Comment
Gurpreet Singh, assistant professor of mechanical and nuclear engineering at Kansas State University and his student researchers are the first to demonstrate that a composite ‘paper’ made of interleaved molybdenum disulfide and graphene nanosheets can be both an active material to efficiently store sodium atoms and a flexible current collector. The idea is a new […]
