Solution route synthesis of InSb, Cu<inf>6</inf>Sn<inf>5</inf>and Cu<inf>2</inf>Sb electrodes for lithium batteries

A solution method was used to prepare InSb, Cu6Sn5and Cu2Sb intermetallic compounds that are of interest as negative electrode materials for lithium batteries. The compounds were synthesized by the reduction of dissolved transition metal- and metalloid salts with fine Zn powder. Heterogeneous redox...
