Encapsulating Mo-Doped TiO2 Anatase in N-Doped Amorphous Carbon With Excellent Lithium Storage Performances

Abstract: To improve the capability, cycling stability and rate capacity of anatase TiO 2-based electrode, Mo-doped TiO 2 anatase encapsulated in nitrogen-doped amorphous carbon (denoted for Mo-TiO 2 @NC) were synthesized using a facile hydrothermal method followed by a coating with polyaniline (PANI) and heating treatment. When tested as an anode for lithium ion batteries, the Mo-TiO 2 @NC electrode showed an initial discharge and charge capacity of 850.7 and 548.3 mAh g −1 at a current density of 85 mA g −1 , respecti… Show more

“…However, after 600 cycles, the discharge capacity remained at 219.1 mA h g À1 . Compared with the recently reported TiO 2 , 9,14,[26][27][28][29] europium-modified TiO 2 showed an excellent long-term cyclability (see Table 2). Due to the introduction of Eu 3+ /Eu 2+ doping in TiO 2 , the high rate discharge capacity and long-term cycling of TiO 2 were improved; thus the lithium storage performance of TiO 2 was improved.…”

“…7 In addition, when doping a cation into a Ti 4+ site of TiO 2 , the kinetics can be greatly improved and the electronic conductivity of the materials can be significantly increased, which helps to improve the capacity transport, cycle life and rate ability. 8 The reported dopants include Mo 5+ /Mo 6+ , 9 Fe 3+ , 10 Ti 3+ , 11 Mn 2+ , 12,13 Cu 2+ , 14 and Ni 2+ , 15 which increased the donor density of TiO 2 . Ti 4+ can be reduced to Ti 3+ by high oxidation metal ions (such as Mo 6+ ) while vacancies can be produced by lower oxidation metal ions (such as Mn 2+ ) in the oxygen sublattice.…”

“…Mo-doped TiO 2 NPs and Nb doped TiO 2 films can be used for this purpose due to their high transparency and high electrical conductivity. 172,173 However, depending upon the types of materials mixed, nanoparticles may undergo agglomeration. Properties of the final product are also determined by the quantity of nano-materials used.…”

“…A few methods, such as the electrochemical anodization [36][37][38][39], atomic layer deposition (ALD) [40][41][42] and hydrothermal synthesis [43][44][45] have been developed for the preparation of metal oxide nanotubes [45][46][47][48][49][50][51]. ALD is a template-assisted technique for the synthesis of nanotubular arrays and requires post-processing separation of the obtained tubes from the template [52].…”
