Cubic Li2SnS3 with NaCl structure and the solid solution with Li3NbS4 were developed by mechanochemical synthesis. Cubic Li2SnS3 is a metastable phase, and the previously reported monoclinic Li2SnS3 is a stable phase. Cubic Li2SnS3 acts as an ionic conductor, and the solid solution of Li3NbS4-Li2SnS3 can be used as an electrode active material in lithium secondary batteries. Li2.933Nb0.8Sn0.267S4 and Li2.857Nb0.571Sn0.571S4 shows large reversible capacities of 318 and 286mAhg-1, respectively. The capacity of these materials depends less on the niobium content than on the electrical conductivity. The reversible capacity in the 2-V region is mainly attributable to redox reactions involving rather sulfur than tin.
