摘要: β-Ni (OH) 2 was constructed into a three-dimensional mesoporous film on Ni foam with ultra-thin (∼ 6 nm) primary nanowalls showing ultrahigh specific capacitance (2675 F g− 1) and excellent cycling performance (> 96% for 500 cycles). The capacitance was higher than theoretical value possibly due to the combination of Faradic and electrical double-layer capacitances.
