“…[29] Ni-Al LDHs doped with Co can facilitate the intercalation of protons with the increase of interlayer spacing (see Table 1). [47] To further quantify the rate performance of the Co 0.6 Ni 0.4 -Al LTHs electrode, CP measurements were carried out at different current densities, and the discharge curves are shown in Fig. 8.…”

Nanostructured Co x Ni 1−x -Al layered triple hydroxides (Co x Ni 1−x -Al LTHs) have been successfully synthesized by a facile hydrothermal method using glycine as chelating agent. The samples were characterized by Xray diffraction, thermogravimetry, Fourier transform infrared spectroscopy and scanning electron microscopy. The morphologies of Co x Ni 1−x -Al LTHs varied with the Co content and its effect on the electrochemical behavior was studied by cyclic voltammetry and galvanostatic chargedischarge techniques. Electrochemical data demonstrated that the Co x Ni 1−x -Al LTHs with Co/Ni molar ratio of 3:2 owned the best performance and delivered a maximum specific capacitance of 1,375 Fg −1 at a current density of 0.5 A g −1 and a good high-rate capability. The capacitance retained 93.3% of the initial value after 1,000 continuous charge-discharge cycles at a current density of 2 A g −1 .

“…α-Ni(OH) 2 materials have been prepared with cationic substitutions of the lattice Ni with Al [16,[67][68][69][70][71][72][73][74][75], Mn [76,77], Fe [78,79], Co [14,69,74,75,[80][81][82], Cu [67,83], Zn [65,66,70,84,85], Y [86] and Yb [87]. In some of these examples, the bivalent Ni 2+ cation is replaced with a trivalent species (e.g.…”

Nickel hydroxides and related materials: a review of their structures, synthesis and properties

This review article summarizes the last few decades of research on nickel hydroxide, an important material in physics and chemistry, that has many applications in engineering including, significantly, batteries. First, the structures of the two known polymorphs, denoted as α-Ni(OH) 2 and β-Ni(OH) 2 , are described. The various types of disorder, which are frequently present in nickel hydroxide materials, are discussed including hydration, stacking fault disorder, mechanical stresses and the incorporation of ionic impurities. Several related materials are discussed, including intercalated α-derivatives and basic nickel salts. Next, a number of methods to prepare, or synthesize, nickel hydroxides are summarized, including chemical precipitation, electrochemical precipitation, sol-gel synthesis, chemical ageing, hydrothermal and solvothermal synthesis, electrochemical oxidation, microwaveassisted synthesis, and sonochemical methods. Finally, the known physical properties of the nickel hydroxides are reviewed, including their magnetic, vibrational, optical, electrical and mechanical properties. The last section in this paper is intended to serve as a summary of both the potentially useful properties of these materials and the methods for the identification and characterization of 'unknown' nickel hydroxide-based samples.

“…The precursor particles exhibit the particle size of 1 3 ȝm. The K sp value of Co(OH) 2 (K sp =5.9u 10 15 ) is similar to that of Ni(OH) 2 (K sp =5.5u 10 16 ), which results in the even agglomeration of crystallite from all the directions [16] . Moreover, the homogeneous decomposition of urea and the use of microwave radiation are also helpful to the control of precursor particles shape and size.…”
