The CR2032-type coin cells were used to perform all electrochemical studies for bare NCM811 and NC-coated NCM811 materials. The lithium foil was employed as a negative electrode to analyze the electrochemical performance of bare and NC-NCM811 cathode. The bare NCM811 and NC-coated NCM811 were used as active materials with the denka black as the conducting carbon and polyvinylidene difluoride (PVDF) as a binder. The active material, conductive carbon, and binder were thoroughly mixed in the weight ratio of 8:1:1 respectively. An adequate amount of N-methyl-2-pyrrolidone (NMP) is added as a solvent to make a viscous slurry and laminated on a clean battery-grade aluminum foil (10 µm thickness). The laminated aluminum sheet was allowed to dry naturally overnight at room temperature followed by drying at 120 °C for 5 h. Then, the dried foil was roll-pressed to ensure uniform distribution in the thickness of the electrode. The electrodes were punched by a 14 mm diameter die and circular disc electrodes were collected which were again dried in a vacuum at 100 °C for 5 h. The assembly of coin cells was carried out inside an argon-filled glove box in which a 14 mm punched cathode acts as a working electrode, 18 mm Celgard 2340 as a separator, and 16 mm lithium metal foil as a reference electrode. During the assembly of coin cells, an adequate amount of 1M LiPF6 dissolved in an EC:DEC = 1:1 volume ratio was added in drops as a liquid electrolyte and the coin cell was crimped. The electrochemical analysis of coin cells like galvanostatic charge-discharge and rate capability studies were carried out by using a Neware battery cycler at room temperature.
