They studied initially on metal oxides have been published in the last August issue of “Nature Communications” magazine. While researchers have since found that manganese dioxide nanosheets better performance than titanium dioxide, but the new thesis is to clarify the mechanism of their work.
Nazar said: “Prior to the development of new materials, you must focus on this phenomenon, they find the operation mechanism.” The researchers found that the chemical activity of thin surface manganese dioxide nanosheets can be better fixed sulfur cathode, and eventually made a charge can be recycled over 2000 cycles of high-performance cathode materials.
The researchers said that a similar solution Vulcan Rodel this material surface chemistry in 1845 and the golden age of German chemical sulfur found in chemical reactions. Nazar said: “The irony is that now scientists have been very few studies of sulfur chemistry and even taught a long time ago so we had to go to the literature, to understand this technology may change our future for all. . ”
First author, University of Waterloo Xanto postdoctoral and graduate Connor Hart, Paris also found that graphene oxide also seems to have a similar working mechanism. They are currently investigating other oxides, in order to determine the most effective sulfur fixing material.
Professor Nazar will (AAAS) annual meeting to make a more detailed presentation at the AAAS this lithium-sulfur battery technology.
