A nanostructured lithium manganese oxide (Li x MnO z ) synthesized by reducing lithium permanganate with methanol in presence of lithium hydroxide has been mixed with conductive carbon in two different ways: ball milling and mixing in a mortar and pestle. The manganese oxide-conductive carbon composite cathodes thus obtained are characterized by electrochemical discharge-charge, density,...
Influences of processing parameters on the formation of WC-Co nanocomposite powder employing polyacrylonitrile as a carbon source have been investigated systematically. The processing parameters investigated include firing time and temperature, addition of a small quantity of cobalt acetate initially as a catalyst, and the sample quantity for a given firing scheme. The investigation provides basic...
