Necklace-like Si@C nano?bers as robust anode materials for high performance lithium ion batteries

引用

Science Bulletin 2019年第4期64卷 261-269页

作者： Xiangzhong Kong Yuchao Zheng Yaping Wang shuquan liang Guozhong Cao Anqiang Pan School of Materials Science & Engineering Central South University Department of Materials Science & Engineering University of Washington Key Laboratory of Nonferrous Metal Materials and Engineering Ministry of Education Central South University

Silicon is believed to be a promising anode material for lithium ion batteries because of its highest theoretical capacity and low discharge potential. However, severe pulverization and capacity fading caused by huge volume change during cycling limits its practical application. In this work, necklace-like N-doped carbon wrapped mesoporous Si nanofibers(NL-Si@C) network has been synthesized via electrospinning method followed by magnesiothermic reduction reaction process to suppress these issues. The mesoporous Si nanospheres are wrapped with N-doped carbon shells network to form yolk-shell ***, the distance of adjacent Si@C nanospheres can be controllably adjusted by different addition amounts of SiO_2 nanospheres. When used as an anode material for lithium ion batteries, the NL-Si@C-0.5 exhibits best cycling stability and rate capability. The excellent electrochemical performances can be ascribed to the necklace-like network structure and N-doped carbon layers, which can ensure fast ions and electrons transportation, facilitate the electrolyte penetration and provide finite voids to allow large volume expansion of inner Si nanoparticles. Moreover, the protective carbon layers are also beneficial to the formation of stable solid electrolyte interface film.

Nitrogen/sulfur co-doped hollow carbon nanofiber anode obtained from polypyrrole with enhanced electrochemical performance for Na-ion batteries

引用

Science Bulletin 2018年第2期63卷 126-132页

作者： Zhigao Luo Sainan Liu Yangshen Cai Shi Li Anqiang Pan shuquan liang School of Materials Science and Engineering Central South University Key Laboratory of Nonferrous Metal Materials Science and Engineering Ministry of Education Central South University

Polypyrrole and sulfur derived hollow carbon nanofibers co-doped with nitrogen/sulfur are synthesized and applied as the anode for Na-ion batteries(NIBs). Successful doping of hollow carbon nanofiber with nitrogen and sulfur is confirmed by X-ray photoelectron spectroscopy, scanning and tunneling electron microscopy. Further analysis certifies that sulfur doping has a significant impact in improving the elecctrochemical performance of the carbon-based anodes for NIBs. The obtained N-doped hollow carbon nanofiber and N/S co-doped hollow carbon nanofiber exhibit similar morphologies but different electrochemical behavior. As expected, the N/S co-doped hollow carbon nanofiber anode exhibits enhanced electrochemical performance, including high specific capacity, outstanding long-term stability, and good rate stability.
