“…The relationship between the anodic peak current I p and the scan rate v is shown in Fig.6 (5). The linear relationship between I p and v 1/2 indicates that the electrode reaction is controlled by proton diffusion [12,17]. According to RandleeSevcik equation [16,19], the anodic peak current I p and the scan rate v of the electrode system controlled by diffusion process follows the following relationship at room temperature (25 C):…”

“…In order to prepare stabilized a-Ni(OH) 2 , researchers have done a lot of work and made certain progress. Usually, the stabilized aNi(OH) 2 can be prepared by doping metal elements in nickel salt solution, such as Al [5e8], Mn [9,10], Zn [11], Cu [12], Fe [13], Yb [14], Y [15], while the prepared sample is b-Ni(OH) 2 without doping metal elements. Recent studies have shown that the structural stability and electrochemical performance for multi-doped a-Ni(OH) 2 are better than that for mono-doped a-Ni(OH) 2 [16].…”

Co substituted nanonickel hydroxide, which used NiCl 2 and Na 2 CO 3 as nickel source and buffer respectively, was synthesised by ultrasonic method. XRD, TEM, PSD and EDS were used to characterise the physical and electrochemical performance of the prepared samples respectively. The electrochemical performance affected by Co substituted ratio and buffer content were determined by cyclic voltammogram and discharge-charge test. The results demonstrated that the Co substituted nanonickel hydroxide was the mixed phase of a-and b-Ni(OH) 2 and the increasing Co content led to the larger proportion of a-nickel hydroxide. An increase in Na 2 CO 3 content was beneficial to form a-nickel hydroxide. The morphology of all samples was the needlelike and the length/diameter ratio decreased with increasing Na 2 CO 3 content. Composite electrodes were made by mixing 8 wt-% nickel hydroxide with commercial b-nickel hydroxide. The discharge capacities of electrodes first increased and then decreased with the change of Na 2 CO 3 content. When Ni 2z was 0?4 mol L 21 and Na 2 CO 3 was 0?5 g, the electrode had the maximum discharge capacity, which reached 306?9 mAh g 21 at 0?5 C discharge/charge rate.

“…Besides, materials, especially ultrafine powders, have been prepared ultrasonically, with the crystal structures and particles sizes changed successfully [9][10][11][12]. Thereby motivated, cubic Sb 2 O 3 crystals were synthesized in this study by introducing ultrasound in neutralizing Sb 4 O 5 Cl 2 with ammonium hydroxide.…”

The processes and conditions for ultrasonic preparation of cubic Sb2O3 crystals under ultrasonic by neutralizing Sb4O5Cl2 with ammonium hydroxide were researched. The effects of ultrasonic power, time and temperature as well as ratio of Sb4O5Cl2 to water on the crystal form and particle size of Sb2O3 were investigated by X-ray diffraction, scanning electron microscopy and laser particle size analyzer. Cubic Sb2O3 crystals were prepared by being sonicated at 100W and 20°C for 30min. The particles were cubic-like, with the average size of 0.777μm.
