The nano-structural LiFePO 4 /C composites with different interfacial structures were investigated. Fe L-edge XAS spectra indicated that the formation of Fe 3+ was related to the interfacial properties of the C-LiFePO 4 . C K-edge and O K-edge XAS sp

Single-crystalline α-MnO 2 nanotubes were synthesized by hydrothermal method. The growth of α-MnO 2 nanotubes is through the formation of the core (γ-MnO 2 )-shell (α-MnO 2 ) nanofibers, and then through the formation of the cavity by the dissolu

Electrochemical performance of LiFePO4/C should be strongly dependent on the carbon coating structure for core-shell nanocomposites. In this work two types of LiFePO4/C composites with the same carbon coating thickness were prepared using a sol–gel
