Tuning Shell Thickness of MnO/C Core-shell Nanowires for Optimum Performance of Lithium-ion Batteries

引用

Chemical Research in Chinese Universities 2017年第6期33卷 924-928页

作者： zhang Dan LI Guangshe FAN Jianming LI baoyun LI Liping State Key Laboratory of Inorganic Synthesis and Preparative Chemistry College of Chemistry Jilin University Changehun 130012 P. R. China Key Laboratory of Design and Assembly of Functional Nanostructures Fujian Institute of Research on the Structure of Matter Chinese Academy of Sciences Fuzhou 350002 R R. China

MnO/C core-shell nanowires with varying carbon shell thickness were synthesized via calcining resorci- nol-formaldehyde resin（RF） with different amounts of hydrothermally synthesized MnO2 nanowires. The relationship between the carbon shell thickness and the anode performance of the MnO/C materials was discussed. With a suitable carbon shell thickness（6.8 nm）, the MnO/C core-shell nanowires exhibit better cycling and rate performance than those with a smaller or larger thickness. The TEM results show that after 50 cycles, the core-shell structure with this thickness can be retained, which leads to superior performance. This contribution provides a significant guiding model for optimizing the electrochemical performance of MnO/C core-shell materials by controlling the thickness of carbon shells.
