Layer Structured α‑Fe₂O₃ Nanodisk/Reduced Graphene Oxide Composites as High-Performance Anode Materials for Lithium-Ion Batteries

A composited anode material with combined layered α-Fe₂O₃ nanodisks and reduced graphene oxide was produced by an in situ hydrothermal method for lithium-ion batteries. As thin as about 5-nm-thickness α-Fe₂O₃ nanosheets, open channels, and face-to-face tight contact with reduced graphene oxide via oxygen bridges made the composite have a good cyclability and rate performance, especially at high charge/discharge rates

Rutile-TiO₂ Nanocoating for a High-Rate Li₄Ti₅O₁₂ Anode of a Lithium-Ion Battery

Well-defined Li₄Ti₅O₁₂ nanosheets terminated with rutile-TiO₂ at the edges were synthesized by a facile solution-based method and revealed directly at atomic resolution by an advanced spherical aberration imaging technique. The rutile-TiO₂ terminated Li₄Ti₅O₁₂ nanosheets show much improved rate capability and specific capacity compared with pure Li₄Ti₅O₁₂ nanosheets when used as anode materials for lithium ion batteries. The results here give clear evidence of the utility of rutile-TiO₂ as a carbon-free coating layer to improve the kinetics of Li₄Ti₅O₁₂ toward fast lithium insertion/extraction. The carbon-free nanocoating of rutile-TiO₂ is highly effective in improving the electrochemical properties of Li₄Ti₅O₁₂, promising advanced batteries with high volumetric energy density, high surface stability, and long cycle life compared with the commonly used carbon nanocoating in electrode materials
