Abstract
Single-layer and few-layer transition metal dichalcogenides have been extensively studied for their electronic properties, but their energy-storage potential has not been well explored. ThiS:paper describes the structural and electrochemical properties of few-layer TiS2, nanocrystals. The two-dimensional morphology leads to very different behavior, compared to corresponding bulk materials. Only small structural changes occur during lithiation/delithiation and charge: storage characteristic's are consistent with intercalation pseudocapacitance, leading to materials that exhibit both high energYand power density.
