Superior functional and electrochemical detection of baddeleyite (ZrO2) for novel supercapacitors slurry electrodes

The zirconia (zirconium dioxide) is fabricated using solid state sintering technique. The XRD and their refinement data declare the proper growth of ZrO₂ materials. The modest value X2 (goodness of fit 1.558) shows that proper symmetrical formation of crystal. The XRD pattern shows the single symmetrical formation of baddeleyites. The different parameters like lattice constant, angle beta, atomic sites, wyckoff position and R-profile components are obtained from software. There is no secondary peak and distortion is elucidated. The diamond software shows the seven-fold of cations linkage present in ZrO₂ symmetry. The clear monoclinic grain formation without any stacking is observed in SEM analysis. The characteristic stretching and bending vibration of metal ions between 503-617 cm-1 is identifying the single zirconia phase with FTIR analysis. The specific capacitance 502, 432, 347, 316 and 262 F/g are observed at 10,20,30,40 and 50 mVs^-1 respectively utilizing the Cyclic Voltametric data. These values cross matched with the charging and discharging (GCD) and electrochemical impedance spectroscopy (EIS) analysis. It is found in the range of 546-282 F/g in GCD while for EIS it is observed in the range of 487-254 F/g which can be used as novel walnut shells bas slurry electrode production, especially for supercapacitors working electrode.
