Fig. 1 shows the SEM images of the synthesized samples. Ni(OH)2-PAM presents itself as fluffy wadding with metastable ring-like which consists of sparse sheets, and the ring-like has an average particle size of about 0.5 µm (from the inset). Ni(OH)2-CTMAB looks like pompon sphere with an average particle size of about 3 µm, and Ni(OH)2 are flower structures but with larger size (4.8 µm) than the other two. The X-ray powder diffraction patterns of Ni(OH)2-PAM, Ni(OH)2-CTMAB and Ni(OH)2 are depicted

Ni(OH)(2) samples were synthesized by hydrothermal process, accompanied with poly(acrylamide) (PAM) or cetyltrimethylammonium bromide (CTMAB) as structure-directing reagents. Under the effects of PAM and CTMAB, both of the Ni(OH)(2) samples show wider pore size distribution, especially more mesopores. Besides, Ni(OH)(2)-PAM presents fluffy wadding, and Ni(OH)(2)-CTMAB looks like pompon sphere. The Ni(OH)(2)-PAM and Ni(OH)(2)-CTMAB based electrodes have a specific capacitance of 1200 and 757 F g(-1), respectively at the discharge current density of 1 A g(-1), much higher than that of Ni(OH)(2) ...
