In a comparison to MoS2 Comm, hydrothermally synthesized MoS2 materials do not show the pronounced plateau behavior of the 2H-to-1T phase transition at 1.1 V during first cycle, likely as a consequence of their high 1T phase content demonstrated by Raman. Only in MoS2 TU it is visible to some extent. It can be also observed on the cyclic voltammograms during the first few cycles (Fig. ). The ICEs of the samples are 70% for MoS2 TU, 59% for MoS2 TAA and 67% for MoS2 LC, possibly caused by irreversible parasitic reactions at the electrode/electrolyte interface (considering lower ICE for samples with higher SSA) and remaining 2H-to-1T phase transition (specifically for MoS2 TU). Each hydrothermally synthesized MoS2 shows higher reversible (de)lithiation capacity than commercial MoS2
