    Variation of LiNiO2 cathode properties with substitution of Ga, In and Tl by the combustion method

    LiNi1-y MyO2 (M = Ga, In and Tl, y = 0.010, 0.025 and 0.050) with small y were synthesized by the combustion method by calcining in an O2 stream at 750 °C for 36 h. XRD analyses, SEM observation a...

    Influences on the H2-sorption properties of Mg of Co (with various sizes) and CoO addition by reactive grinding and their thermodynamic stabilities

    We attempted to improve the H2-sorption properties of Mg by mechanical grinding under H2 (reactive grinding) with Co (with various particle sizes) and with CoO. The thermodynamic stabilities of the added Co and C...
