in the positive electrodes of rechargeable alkaline batteries. The powder X-ray diffraction (XRD) analysis shows that the addition of MCNTs induces more structural defect within the crystal lattice of the nickel...-nickel hydroxide powder as active material to prepare the pasted electrodes. They found that the CNTs addition can increase the material utilization and specific discharge capacity of nickel hydroxide......
is temperature of preparing Ni powder with precursor) Fig.5 shows that the morphology of Ni particles prepared from nickel hydrazine complex is less- agglomerated and better-spherical. In addition, the average... a mixture of complexes, [Ni(N2H4)2]Cl2 and [Ni(N2H4)3]Cl2, was formed with [N2H4]/[Ni2+] at 3.0 and 4.0 at 25℃. The reduction of Ni2+ to metallic Ni powder proceeded via the formation of nickel hydroxide......
