Carbon filaments, when surface treated and used in stead of carbon black as the conductive additive to MnO 2 cathodes in lithium cells, produced a more gently sloping discharge curve (desirable for applications requiring end-of-life indication). These filament composite cathode plates also occupied less volume (higher packing density) and were handleable without the use of a binder, thus...
Due to the poor electric conductivity but the excellent catalytic ability for the oxygen reduction reaction (ORR), manganese dioxide in the α phase (denoted as α-MnO2) anchored onto carbon black powders (XC72) has been synthesized by the reflux method. The specific surface area and electric conductivity of the composites are generally enhanced by increasing the XC72 content while the high XC72 content...
