Enhancing conductivity and stabilizing structure of the TiN/SnO2 embedded in ultrathin graphite nanosheets as a high performance anode material for lithium ion batteries

[Display omitted] The composite of TiN/SnO2@C nanosheets has been synthesized via ball milling. In the sheet-like structure, the TiN/SnO2 nanoparticles were evenly anchored in the graphite nanosheets. The TiN nanoparticles can not only increase the electron conductivity, but also stabilize the structure in Li+ insertion/extraction. Besides, the sheet-like graphite can accommodate the volumetric expansion during cycling. Consequently, high specific capacity (837.0 mAhg−1 after 100 cycles at 0.2 Ag−1), remarkable rate property (466.8 mAhg−1 at 5.0 Ag−1) and long-life cycling performance for the TiN/SnO2@C nanosheets can be achieved in electrochemical performance measurement. The composite of TiN/SnO2@C nanosheets will become promising anode material for lithium ion batteries in the next generation.
