The Tesla Gigafactory, Tesla Motors brainchild, not only holds the promise of an electric-vehicle future in the United States, but much more. Tesla Motors has been extolled, by some at least, as an American success story and, in many ways, it is. True, a few hundred million dollars went out in loans, but the company […]

Researchers from University of Pittsburgh discovered that the performance of lithium-ion batteries and super capacitors made from graphite and graphene is affected by their exposure to water. The study published last week in Nature Materials shows that opposite to common beliefs graphite and graphene have hydrophilic properties. The idea for the research came as a […]

The MIT researchers could easily change the balance towards Li-air batteries in the near future just by changing the actual electrode materials. In the paper published in the journal Electrochemical and Solid-State Letters, the researchers showed that by changing the carbon electrodes with gold or platinum electrodes as a catalyst, the efficiency of the battery will increase.
