Ni–57 mass%Sn alloy has been examined as a new anode material for Li-ion batteries. Li ions can reversibly intercalate and de-intercalate in this alloy. Ball milled nanocrystalline and subsequently annealed microcrystalline Ni–57 mass%Sn alloy showed very high initial discharge capacity. The cell capacity decayed rapidly after the first discharge. The capacity of the ball milled Ni–57 mass%Sn alloy faded continuously on cycling, while the annealed alloy exhibited good cyclic properties. Therefore, Ni–57 mass%Sn alloy is an attractive intercalation host for Li.
