Synthesis of Different Molybdenum Disulfide Nanostructures and their Applicability in Lithium Ion Batteries with Ionic Liquid Electrolytes

摘要

Molybdenum disulfide (MoS_2) nanostructures with three different morphologies are synthesized and tested with respect to their applicability in lithium ion batteries. Thereby, electrolytes based on ionic liquids are used. The electrochemical performance of nanostructures and thin films is compared to evaluate the influence of the morphology. Characterization methods include X-Ray diffraction (XRD), cyclic voltammetry (CV), galvanostatic cycling and thin film calorimetry. The thin film and the nanostructured samples show a reversible capacity of 525 mAh/g and a maximum capacity 225 mAh/g, respectively.
