Rational construction and decoration of Li5Cr7Ti6O25@C nanofibers as stable lithium storage materials

One-dimensional N-doped carbon nanofibers produced by pre-oxide treatment for effective lithium storage

“…3a, the XPS spectrum of C 1s can be fitted with four characteristic peaks located at 284.4, 285.3, 286.4, and 288.0 eV, corresponding to the bonds of C–C, C–N, C–O, and CO, respectively. 25,28–30 It can be seen that the peak of the CO functional group weakens as the temperature increases, indicating that the precursor is decomposed more completely during the heating process, which is consistent with the FT-IR results. In the XPS high-resolution spectrum of N element (Fig.…”

Templated synthesis of 2D TiO2 nanoflakes for durable lithium ion batteries

“…4b is the high-resolution XPS spectrum of Ti 2p, in which a pair of obvious characteristic peaks for Ti 4+ 2p 1/2 and Ti 4+ 2p 3/2 locate at 464.8 eV and 459.1 eV, respectively. 21 Besides, a pair of weak characteristic peaks for Ti 3+ 2p 1/2 and Ti 3+ 2p 3/2 are located at 463.8 eV and 458.3 eV. In Fig.…”

Li2SiO3 Modification of C/LiFe0.5Mn0.5PO4 for High Performance Lithium‐Ion Batteries

“…As show in Figure S4a, three distinct peak kinds may be seen in the C 1s. the two peak s at 284.8 and 285.8 eV correspond to C−C and C−O bonds, respectively [40] . As show in Figure S4b, The fitted peak at 531.7 eV of the O 1s spectrum may be attributed to metal‐oxygen bonds, while the peak at 533.4 eV relates to trace amounts of adsorbed H 2 O molecules at or near the surface [41] .…”
