A Dude Who Just Sold His UGT1A7 Novel For A Few Million Usd
001 and 3?V at a current density of 0.1?A?g?1[188]. Double-sandwich-like SnS2/graphene composite was also prepared, retaining a capacity of 564?mAh?g?1 after 60 cycles [189]. Zhuo et al. synthesized SnS2/graphene nanosheets composite, and achieved a high capacity of 1114?mAh?g?1 with excellent retention of 96% after 30 cycles [190]. It was noted that reducing the size of SnS2 in the composite could improve the cycling stability. Cao et al. greatly improved the cycle life of SnSx/graphene composite (1?Selleckchem R428 stability [192]?and?[193]. Besides, other metal sulfide/graphene composites have also been fabricated and evaluated, showing much improved stability and rate capability [32], [38], [40], [48], [194]?and?[195]. These results without exception confirmed the advantages of UGT1A7 graphene as a superior building block for transition metal sulfide composite. Chao et al. fabricated a bind-free and flexible electrode consisting of ultrathin MoS2 nanosheets grown on the surface of an active carbon fiber (ACF) cloth [196]. The composite anode delivered capacity as high as 971?mAh?g?1 at a current density of 0.1?A?g?1, and remaining 418?mAh?g?1 after 200 cycles at a current density of 0.5?A?g?1. The superior electrochemical performance of the composite could be attributed to its robust structure, synergistic effects of ultrathin MoS2 nanosheets and hierarchically porous configuration (Fig. 13). Due to its binder free structure and no need of current collector, the MoS2/ACF Crizotinib in vivo cloth electrode could greatly enhance the practical energy density when used in flexible LIBs. Flexible and freestanding MoS2/C hybrid nanofibrous mats have also been fabricated by electrospinning-carbonization method, which exhibited a stable capacity of 890?mAh?g?1 at a current density of 0.1?A?g?1, and ?350?mAh?g?1 at an elevated current density of 1.0?A?g?1[197]. This approach enabled large scale preparation of high performance MoS2 electrodes and also provided a general strategy for free standing electrodes for flexible batteries or capacitors (Fig. 14). Transition metal sulfide composites with other materials have also been reported, such as SnS2/SnO2, Fe3O4/MoS2, SnS2/Si and Ce-doped SnS2, showing improved performances for Li storage in comparison with the bare materials [198], [199], [200], [201]?and?[202]. In addition to them, transition metal sulfide/polymer composites were also expected to serve as outstanding candidates. For example, Lemmon et al. reported a binary MoS2/polyethylene oxide (PEO) nanocomposite and a ternary MoS2/PEO/graphene nanocomposite for anode materials in LIBs [72]?and?[203].
