Solid solution of Li2TiS3 (Li8/3Ti4/3S4) and Li3NbS4 were prepared using mechanochemical syntheses. The materials with cubic rock-salt structure were obtained over the full range of compositions (Li(8+x)/3Ti(4-4x)/3NbxS4; 0 ≤ x ≤ 1). Lithium, titanium, and niobium randomly share the cationic site. Each material showed electrode activity and had a large reversible capacity of more than 350mAhg-1 with more than 3 electron process per composition formulas of Li(8+x)/3Ti(4-4x)/3NbxS4.
