Enhanced electrochemical performance of carbon-coated TiO2 nanobarbed fibers as anode material for lithium-ion batteries

High-Temperature Stable Anatase Titanium Oxide Nanofibers for Lithium-Ion Battery Anodes

“…This issue is extremely critical in the electrospinning process. The electrospinning process has been widely utilized to fabricate TiO 2 -based LIB anodes − because the resulting nanofibers have a large electrochemically active surface area and short diffusion length for Li ions. In general, the polymeric matrix in electrospun TiO 2 nanofibers should be removed by an annealing process to form inorganic nanofibers for LIB applications. − For example, the poly­(vinylpyrrolidone) phase in electrospun nanofibers can be completely removed at a temperature as high as 500 °C .…”

(N/S)‐TiO2@C‐Nanosphere Anode Materials with Prominent Electrochemistry Performance Synthesized by Pyrolysis of In Situ Coated Polypyrrole

“…[13][14][15] Some hybrid nanostructured TiO 2 anode with carbonaceous materials have been developed, such as TiO 2 /graphene, [16][17][18][19][20][21][22][23][24] TiO 2 /carbon tubular, [25][26][27] and TiO 2 /carbon nanospheres, to overcome these drawbacks. [11,28,29] These constructed nanostructured TiO 2 /carbon anode materials have relative higher discharge specific capacity; however, they are usually prepared by the electrospinning method and hydrothermal and solvothermal method, which refer to a complex, time-consuming process with low yields and high costs. Therefore, it is difficult to produce in large quantities.…”

Improved conductivity and ionic mobility in nanostructured thin films via aliovalent doping for ultra-high rate energy storage

“…[16][17][18] However, TiO 2 's relatively low intrinsic electronic conductivity and Li + mobility signicantly hinder its high-rate performance. [19][20][21] A variety of TiO 2 morphologies, such as solid particles, 22 hollow particles, 23 bers, 24 tubes, 25 rods, 26 and sheets, 20 have been investigated, all of which have shorter Li + diffusion lengths and enhanced 1dimensional (1-D) charge transport. Recent work has focused on improving the intrinsic conductivity of TiO 2 by modifying its electronic structure through aliovalent doping.…”
