资源简介：
The further application of Ni–Zn aqueous batteries is majorly restricted by nickel-based cathodes due to their low capacity and poor cycling stability, which requires the development of hierarchically nano-structured nickel and nickel oxides. Herein, we prepare a novel nickel-based electrode with hierarchical 3D networks by configuring nanostructured Ni and Ni/NiO nanoparticles onto bamboo-derived cellulose nanofibers (denoted as Ni/NiO-BCF). Owing to the high conductivity of carbonized nanofibers and enhanced Ni/NiO active sites exposed, the Ni/NiO-BCF electrode delivers a capacity of 248 mA h g -1 at 0.625 A g-1and exhibits a good cycling stability (94.5% after 2000 cycles).
