“…This implies that the outer surface of the composite mixture is covered by the SnO 2 and after mixing of SnO 2 nanopowder with -Ni(OH) 2 nanopowder by sonication method, a little change in the disorder turbostatic phase of -Ni(OH) 2 to ordered -Ni(OH) 2 layered structure is indicated by the formation of diffraction peaks (1 0 1), (1 0 2) and (1 1 1). This implies that a small amount of -Ni(OH) 2 could be formed after sonication treatment of the composite mixture in ethanol, which is in agreement with the structural disorder change of the Ni(OH) 2 with the preparation methods and the metal ion dopings are observed in the literature studies [22][23][24]. Figure 2(a) shows the TEM images of SnO 2 spherical nanoparticles dispersed evenly with 10-15 nm size.…”

The nickel hydroxide nanopowders mixed with SnO 2 nanoparticles as an additive in different proportions were prepared and characterised by X-ray diffraction (XRD), transmission electron microscope (TEM) and electrochemical measurement by cyclic voltammetry. XRD examination suggests that the composite Ni(OH) 2 /SnO 2 has both the phases of -Ni(OH) 2 and -Ni(OH) 2 with SnO 2 nanoparticles. TEM images show the nanostructures of nickel hydroxide, SnO 2 and dispersion of SnO 2 nanoparticles on nickel hydroxide particles in the composite. The electrochemical studies revealed that the composite electrode has better redox reversibility and specific capacitance values compared to the pure Ni(OH) 2 , -Ni(OH) 2 and usual -Ni(OH) 2 electrodes and it can be applied as a promising positive active material for alkaline rechargeable batteries.

a-Nickel hydroxide codoped with Al 3+ and Ca 2+ was prepared by chemical coprecipitation method. The phase structure and surface morphology of the prepared samples were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM). The electrochemical performances of the prepared samples were analyzed by cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and charge/discharge tests. XRD and SEM tests reveal that the Al 3+ /Ca 2+ codoped a-nickel hydroxide has a relatively good crystallization and a very coarse surface. Electrochemical tests show that the Al 3+ /Ca 2+ codoped a-nickel hydroxide has higher proton diffusion coefficient, lower electrochemical reaction resistance, and higher discharge capacity (395.3 mAh g −1 at 0.2 C) than the Al 3+ singly doped a-nickel hydroxide, which indicates its potential application as an electrode material for secondary alkaline batteries.
