MoS2 Lithiation Mechanism - Lithium Ion Battery Electrochemistry Data

MoS2 Electrode Manufacturing:Commercial bulk MoS2 was usedMoS2/Carbon Super P/PVDF with a mass ratio of 80:10:10 wt.% was used to make a slurryNMP was used as the solvent for the slurryCopper (11 µm) foil was used as the current collectorDifferent Thicknesses/Mass Loadings with the same formulation were made. Details can be found in the Excel file included.Electrochemical Data:All electrodes were tested in Hohsen CR2032 coin cells with a half-cell configurations including a working electrode, a Celgard separator, 100 µL of 1M LiPF6 in EC/DMC (3:7 vol.) electrolyte, a lithium metal counter electrode, a 1 mm spacer, and a spring.Mass (mg) of each electrode used can be found in the Excel file included in the upload.Constant Current Data:Voltage Range (3.00 - 0.80 V, 3.00 - 0.60 V, 3.00 - 0.40 V, and 3.00 - 0.01 V)Thickness/Mass Loading I (3.00 - 0.80 V vs. 3.00 - 0.01 V)Thickness/Mass Loading II (3.00 - 0.80 V vs. 3.00 - 0.01 V)Low Voltage Range (1.80 - 0.01 V)Restricted Voltage Range (3.00 - 1.50 V and 3.00 - 0.80 V)Cycling Voltammetry Data:Shallow Discharge (3.00 - 0.80 V)Deep Discharge (3.00 - 0.01 V)Activation (3.00 - 1.30 V and 3.00 - 1.10 V)Electrochemical Impedance Spectroscopy (EIS) Data:Shallow Discharge (3.00 - 0.80 V)Deep Discharge (3.00 - 0.01 V)
