LC show comparably stable cycling behavior with about 86 % of initial capacity retention, whereas MoS2 Comm and MoS2 TU only exhibit about 80 % of capacity retention. Remarkably, this behavior is opposite to their increasing SSA, which is often hypothesized to be a source of capacity fading due to increased parasitic side reactions . It is demonstrated that MoS2 materials with higher SSA exhibit improved cycling stability, regardless of crystallite size. We hypothesize that this behavior is a consequence of reduced volumetric electrode changes during cycling (vide infra). To gain deeper insights into the kinetics of the MoS2-based samples during lithium intercalation, electrochemical impedance spectroscopy (EIS) is carried out at various states of charge along the entire potential range from 3 -1 V vs. Li/Li + (Fig. ). The capacitor-like electrical response (i.e., pseudocapacitive or electrical double-layer contributions to the charge storage process) can be extracted from EIS by employing a simple equivalent circuit consisting of a capacitor and resistor in series . Then, the (pseudo)capacitive response can be presented over a wide potential range as a function of frequency via a so-called 3D Bode plot (Fig. ) with real capacitance representation (Fig. ). For commercial MoS2 Comm, two clear maxima of the real capacitance curve can be found corresponding to the two redox peak potentials (Fig. ). Outside of these peak potentials, there is a significant drop in the real capacitance, in line with a typical battery-like electrochemical response like for example in LiFePO4 . Contrarily, for all three hydrothermally synthesized MoS2 samples (Fig. ), the real capacitance curve changes towards a "waterfall" shape indicating a (pseudo)capacitive charge storage process over a wider potential range. Notably, potential range is narrower for MoS2 TU as compared to the other two samples, MoS2 TAA and MoS2 LC. Overall, 3D Bode analysis gives a comprehensive overview of electrode kinetics over a wide potential and frequency range, with pseudocapacitive lithium intercalation properties for hydrothermally synthesized MoS2
