The findings motivated us to explore the impact of sulfur precursors on the electrochemical lithium intercalation performance of hydrothermally synthesized MoS2 materials. Given the relative ease and scalability of hydrothermal synthesis over synthesis routes like vapor deposition or thermal conversion of molybdenum oxides in sulfidizing atmospheres, gaining better understanding of the relation between hydrothermal synthesis route, MoS2 microstructure and the electrochemical performance are crucial to further develop MoS2 as a promising electrode material in (pseudocapacitive) ion intercalation hosts.
