Abstract

Interconnected mesoporous NiCo2O4 nanosheets can be directly grown on various conductive substrates including Ni foam, stainless steel, Ti foil, and flexible graphite paper through a simple solution method. The NiCo2O4 nanosheets-Ni foam structure exhibits superior pseudocapacitive performance with a high capacitance of 1743 F g−1 under a constant current density of 7.08 A g−1 and a capacitance loss of only 6.7% after 3000 cycles. More details can be found in the article by Xiong Wen (David) Lou and Genqiang Zhang on page 976.
