Abstract

In order to check whether the alloys in the system Mg–Ge can be prepared by sintering method or not, the Mg2Ge powder was fired in argon atmosphere at high temperatures. As a result, it was found that the samples were obtained as sintered alloys. From the electrochemical measurements, next, the sintered materials including copper as a conductive agent were found to work as anode active materials for lithium secondary batteries. When they were fired with the additive component such as ammonium hydrogen carbonate (NH4HCO3), polyvinyl alcohol (PVA) or magnesium powder vanishing during firing, the porous sintered alloys could be prepared, which also worked as anode materials with better cyclic stability than the nonporous ones. These results denoted that the sintering method is valuable and developing for preparation of the alloy materials.
