Outline of Research at the Start

We will study doping of the single-layered 2D-MoS2 based-anodes with
transition metals (TM), such as, scandium (Sc) and yttrium (Y) to induce and modulate spin moment of Mo around sulfur vacancy (Vs). Resulting spin capacitance at the anode/electrolyte interface is expected to boost the ion transport and storage capacity of secondary ion-batteries. Electron spin resonance (ESR) of 2D-MoS2 based-anodes will be performed to study in-situ spin states during intercalation and de-intercalation process at various dopant condition.
