Rice University scientists who want to gain an edge in energy production and storage report they have found it in molybdenum disulfide.  From Wikipedia: “Molybdenum disulfide is the inorganic compound with the formula MoS 2. The compound is classified as a metal dichalcogenide. It is a silvery black solid that occurs as the mineral molybdenite, the principal ore for molybdenum.   MoS 2 is relatively unreactive. It is unaffected by dilute acids and oxygen. In appearance and feel,molybdenum disulfide is similar to graphite. It is widely used as a solid lubricant because of its low friction properties and robustness.” Let’s break down one probably unfamiliar term (it was to your editor).  A chalogen is one of the members of the Vla group in the periodic table and includes oxygen, sulfur, selenium, tellurium, and polonium.  Add a more electropositive element to …

Three Battery Technologies with Great Potential

It’s a good week when at least three battery developments show promise for electric vehicle use in the near future.  One advanced lithium-ion battery from France, a dual-carbon battery from Japan, and a supercapacitor that one can wrap around one’s finger comprise the trio. French Lithium-Tin Dioxide “Synthesizing nanoparticles of tin dioxide (SnO2) in the pores of a carbonaceous material,” researchers at the Institute of Materials Science of Mulhouse and Charles Gerhardt Institute of Montpellier, part of an electrochemical energy storage consortium called RS2E, have found the material to have “remarkable properties.”  Their work is the subject of a patent and published in the journal, Advanced Energy Materials. Researchers, hoping to obtain better performance that that achieved with carbon electrodes, tested …
