Fast ion transport through ultrathin shells of metal sulfide hollow nanocolloids used for high-performance energy storage.

Abstract:

:Metal sulfide (MS, nickel sulfide/copper sulfide) hollow spheres with hierarchical, ultrathin shell structures have been constructed by a facile method. The as-formed MS hollow structures are shown to be uniform in sizes with hierarchical ultrathin shells, which could facilitate the transport of electrolyte ions. Electrochemical evaluations of the as-fabricated MS based materials as supercapacitors electrodes having high large surface area (106-124 m2 g-1) and high specific capacitances (up to 1460 F g-1) with good cycling stability (up to 94% retention after 5000 cycles), showing their potential applications in the next-generation high-performance supercapacitors used for energy storage.
