title: Self-assembly synthesis of a unique stable cocoon-like hematite @C nanoparticle and its application in lithium ion batteries.
abstract: A novel cocoon-like Fe2O3@C nanoparticle was fabricated via a facile hydrothermally molecular self-assembly procedure. Compared to bare Fe2O3nanoparticles, the carbon coated Fe2O3nanoparticles exhibit higher specific capacity, excellent rate capacity and cyclic stability as the anode in lithium ion batteries. These cocoon-like Fe2O3@C nanoparticles carry enhanced lithium storage properties with a reversible capacity of 358mAhg-1after 150 cycles under the current density of 1000mAg-1, while the carbon-free bare Fe2O3can only deliver a much lower capacity of 127.6mAhg-1with a continuously decreasing trend. The excellent performance of Fe2O3@C is attributed to the coated carbon layers, which not only enhance the electronic conductivity but also reduce the stress upon the Fe2O3nanoparticles caused by the volume change during the charge/discharge process.
