    Oxidation-etching preparation of MnO2 tubular nanostructures for high-performance supercapacitors by Zhu, Jixin, Shi, Wenhui, Xiao, Ni, Rui, Xianhong, Tan, Huiteng, Lu, Xuehong, Hng, Huey Hoon, Ma, Jan, Yan, Qingyu

    Published 2013
    “…Among all the types of MnO2 nanostructures prepared, tubular MnO2 nanostructures composed of assembled nanosheets show optimized charge storage performance when tested as supercapacitor electrodes, for example, delivering an power density of 13.33 kW·kg–1 and a energy density of 21.1 Wh·kg–1 with a long cycling life over 3000 cycles, which is mainly related to their features of large specific surface area and optimized charge transfer pathway.…”
