In the field of electrochemical energy storage, MoS2 has been employed as an anode material suitable for lithium and sodium ion storage, with the possibility to store charge via electrochemical intercalation and/or conversion reactions, depending on the utilized voltage window . When used as an intercalation host, it was found that kinetically favorable intercalation properties are obtained when MoS2 crystallite size is reduced . For such nanosized MoS2, Cook et al. report the emergence of solid-solution intercalation with pseudocapacitive properties, that is, Faradaic charge storage with a capacitor-like signature over a wide voltage range in absence of kinetic diffusion limitations . It was also found that the introduction of crystal defects, as well as the increase of the MoS2 d-spacing via hexanediamine pillars amplifies the pseudocapacitive electrochemical lithiation response . For 2H-MoS2, an irreversible transition to 1T-MoS2 during the first electrochemical lithiation cycle at around 1.1 V vs. Li + /Li leads to an unfavorably low initial Coulombic efficiency . The findings underline the significance of controlling MoS2 crystal structure, crystallite size, and morphology, to obtain desired functional properties.
