TiNb2O7 nano-particle decorated carbon cloth as flexible self-support anode material in lithium-ion batteries

Recent Advances in Titanium Niobium Oxide Anodes for High-Power Lithium-Ion Batteries

“…Advanced carbonaceous materials, such as carbon nanofibers (CNFs), carbon nanotubes (CNTs), , ketjen black (KB), graphene, bacterial cellulose carbon (BCC), activated carbon cloth (ACC), carbon nanosheets (CNSs), and heteroatom-doped amorphous carbon from polymer pyrolysis, , are common materials to improve the cycling stability and rate capability of TNO composites. Carbon can not only increase the electronic conductivity of TNO materials but can also reduce TNO and form oxygen vacancies, further increasing the ionic conductivity of TNO materials. , …”

Porous TiNb2O7@N-C as Anode Materials for Lithium-Ion Batteries with Ultrahigh-Rate Performance

“…The successful doping of N is shown in the high-resolution N 1s spectrum (Figure c), where three peaks at 400.5, 398.5, and 395.1 eV can be fitted. The peaks with higher binding energies at 400.5 and 398.5 eV can be attributed to pyrrolic-N and pyridinic-N, respectively. , The lowest energy peak at 395.1 eV can be assigned to the Nb–N bond, caused by the reaction between the N source and Nb during the annealing process. , In Figure d, the Ti 2p spectrum can be fitted to two peaks located at 464.6 and 458.9 eV, corresponding to the Ti 2p 1/2 and Ti 2p 3/2 peaks of Ti 4+ , respectively. , Figure e shows the Nb 3d spectrum with its main peaks at 210.0 and 207.2 eV assigned to the Nb 3d 3/2 and Nb 3d 5/2 core levels of Nb 5+ in TNO@N-C, respectively . The O 1s spectrum has only one main characteristic peak at 530.3 eV (Figure f), which can be attributed to the Nb–O bond in the sample …”

“…9,29 In Figure 2d, the Ti 2p spectrum can be fitted to two peaks located at 464.6 and 458.9 eV, corresponding to the Ti 2p 1/2 and Ti 2p 3/2 peaks of Ti 4+ , respectively. 21,30 Figure 2e shows the Nb 3d spectrum with its main peaks at 210.0 and 207.2 eV assigned to the Nb 3d 3/2 and Nb 3d 5/2 core levels of Nb 5+ in TNO@N-C, respectively. 31 The O 1s spectrum has only one main characteristic peak at 530.3 eV (Figure 2f), which can be attributed to the Nb−O bond in the sample.…”

Defect modulation and luminescence improvement of Mn4+-activated La(Mg, Nb)O3 phosphor with improved stability for plant cultivation

“…S2, ESI †), the peaks at 206.5 eV and 209.2 eV corresponding to the typical peaks of Nb 3d 5/2 and Nb 3d 3/2 verified that niobium kept the +5 valence state while tuning the ratio of Mg/Nb. 26 As the O 1s spectra showed in Fig. 2, the peaks at 529.3 eV and 531.3 eV are associated with lattice oxygen (O I ) and adsorption oxygen (O II ), respectively.…”
