英文摘要	Lavender-like, lightweight, and flexible supercapacitive electrodes with high specific capacitance have been fabricated for the first time by assembling petal-like nano-nickel oxides on nickel spikes that are grown by using a simple non-templated method. Compared with traditional fiber-shaped electrodes, the specific capacitance of these electrodes increases six-fold to 4.47 F cm(-2). For a 1 cm-long spike electrode, the capacitance reaches over 1.4 F, and no evident drop is observed at a bending angle of 180 degrees. Both the mechanical strength and large current discharging property are unexpectedly good. The spike structure makes the apparent mass density of the electrode as light as carbon fiber, and exhibits considerable potential for use in future portable energy-storage devices.; National 973 Projects of China [MOST2011CB933300]; Program for New Century Excellent Talents in the University of China [NCET-13-0631]; State Key Laboratory of Chemical Engineering [SKL-ChE-14A02]; SCI(E); EI; ARTICLE; taocy@cqu.edu.cn; 8; 1100-1105; 2
