摘      要：Architecture of fibrous building blocks with ordered structure and high electroactivity that enables quick charge kinetic transport/intercalation is necessary for high-energy-density electrochemical ***,we report a heterostruc-tured molybdenum disulfide@vertically aligned graphene fiber(MoS_(2)@VA-GF),wherein well-defined MoS_(2)nanosheets are decorated on vertical graphene fibers by C-O-Mo covalent *** from uniform microfluidic self-assembly and confined reactions,it is realized that the unique characteristics of a vertical-aligned skeleton,large faradic activity,in situ interfacial connectivity and high-exposed surface/porosity remarkably create efficiently directional ionic pathways,interfa-cial electron mobility and pseudocapacitive accessibility for accelerating charge transport and intercalation/*** MoS_(2)@VA-GF exhibits large gravimetric capacitance(564 F g^(-1))and reversible redox transitions in 1 M H_(2)SO_(4)***,the MoS_(2)@VA-GF-based solid-state supercapacitors deliver high energy density(45.57 Wh kg-1),good cycling stability(20,000 cycles)and deformable/temperature-tolerant *** that,supercapacitors can realize actual applications of powering multicolored optical fiber lamps,wearable watch,electric fans and sunflower toys.
