In situ synthesis of a graphene/titanium nitride hybrid material with highly improved performance for lithium storage

All Metal Nitrides Solid‐State Asymmetric Supercapacitors

“…As was expected, after high-temperature annealing in amonia atmosphere, three diffraction peaks at 37°, 44°, and 63° appear and correspond well to the face-centered cubic (fcc) TiN (111), (200), and (220), respectively (JC-PDS, #65-0715) which is identical to previous work. [ 27,48 ] Same characterization was conducted to the anode material. (101) and (211).…”

“…They include carbon coating, [22][23][24] carbon nanotube encapsulation, [ 25,26 ] graphene wrapping, [27][28][29][30] and forming core-shell structures with TiO 2 , [ 31 ] VN, [ 32 ] and MnO 2 , [ 33 ] as well as decoration with polymers such as polypyrrole, [ 34 ] polyaniline, [ 35,36 ] and PEDOT. [ 37 ] Those methods showed high effi ciency in enhancing TiN cycling and rate properties.…”

Nanostructured transition metal nitride composites as energy storage material

“…At a current density of 2000 mA g 1 , the hybrid anode still retains 325 mAh g 1 while that of G is only 98 mAh g 1 ( Figure 5(b)) [28]. It is demonstrated that the G/TiN hybrids display superior electrochemical performance owing to the highly efficient mixed (electron and Li + ) conducting network.…”

Investigation of carbon phase evolutions in titanium nitride-carbon nanocomposites prepared in supercritical benzene with respect to their lithium storage capacity

“…The TiN/G nanocomposite conveys a speci c capacity of 381 mAh g 1 at a current density of 0.2 C. Meanwhile, at higher current density of 7.7 C, a remarkable speci c capacity of 133 mAh g 1 is also delivered that represents a good rate capability. It is worth noting that the speci c capacity of G in TiN/G nanocomposites increases as a function of G in proportion up to 641 mAh g 1 at 65% G [7,8]. Afterwards, the extra addition of G leads to decreasing the speci c capacity of G to 218 mAh g 1 at 82% G with C/D rate of 0.5 C, which is almost equal to G performance.…”

“…Therefore, there are great interests in upgrading anode performance by doping TiN into anode matrix. Anchoring of TiN nanoparticles to graphene layers not only promotes the electrical conductivity along caxis, but also suppresses the agglomeration of graphene sheets, resulting in the formation of a exible porous texture [7][8][9][10].…”
