Exceptional electrochemical performance of porous TiO₂–carbon nanofibers for lithium ion battery anodes

Abstract

A porous TiO2–carbon nanofiber anode shows a high capacity of ∼680 mA h g−1 after 250 cycles at 0.1 A g−1.

The study on structure and electrochemical sodiation of one-dimensional nanocrystalline TiO2@C nanofiber composites

“…4b), it was hard to identify the distinct lattice of TiO 2 , indicating its low degree of crystallinity. When the thermal-treatment temperature increased to 550 C, the lattice spacing of 3.52 Å could be detected in the composite, corresponding to [1 0 1] lattice planes of anatase TiO 2 [45]. Nevertheless, with the thermal-treatment temperature further increased to 650 C, apart from the lattice spacing of 3.52 Å, the lattice spacing of 2.48 Å was also detected in the TEM image, which was denoted as the [1 0 1] lattice plane of rutile TiO 2, shown in the Fig.…”

Electrospun carbon-based nanostructured electrodes for advanced energy storage – A review

“…(See Fig. 8d-i) [66]. By controlled heat treatment of PMMA/PS/TiO 2 precursor composite nanofibers, PS is partially decomposed to produce pores and also carbonized to produce the carbon material.…”

Recycled diesel carbon nanoparticles for nanostructured battery anodes

“…Many advanced nanosynthesis approaches have been developed to prepare designed nanostructured materials, such as nanotemplating [11], chemical vapor deposition (CVD) [12], electrospinning technique [13], and flame synthesis [14]. For example, many sacrificial material templates such as anodized aluminum oxide, porous silica, and polystylene particles have been used to synthesize hollow CNFs and carbon capsules [15e18]; the CVD method was used to fabricate CNTs, CNFs, and graphene [10,19]; the electrospinning is a powerful technique to prepare onedimensional (1D) composite nanofibers and nanotubes [7,8]; and carbon nanoparticles can also be prepared by fast single-step flame synthesis [14].…”
