Nano Research 2018年第5期11卷 2460-2469页

作者： Biwu Wang Jingjing Zhang Zhigang Xia Meiqiang Fan Chunju Lv Guanglei Tian Xiaona Li Department of Materials Science and Engineering China Jiliang University (CJLU) Hangzhou 310018 China College of Metrology and Measurement Engineering China Jiliang University (C.ILU) Hangzhou 310018 China Hefei National Laboratory for Physical Science at Microscale and Department of Chemistry University of Science and Technology of China Hefei 230026 China

In this work, we developed a polyaniline （PANI）-coated selenium/carbon nanocomposite encapsulated in graphene sheets （PANI@Se/C-G）, with excellent performance in Li-Se batteries. The PANI@Se/C-G nanostructure presents attractive properties as cathode of Li-Se batteries, with a high specific capacity of 588.7 mAh·g^-1 at a 0.2C （1C = 675 mA·g^-1） rate after 200 cycles. Even at a high rate of 2C, a high capacity of 528.6 mAh·g^-1 is obtained after 500 cycles. The excellent cycle stability and rate performance of the PANI@Se/C-G composite can be attributed to the synergistic combination of carbon black （as the conductive matrix for Se） and the double conductive layer comprising the uniform PANI shell and the graphene sheets, which effectively improves the utilization of selenium and significantly enhances the electronic conductivity of the whole electrode.
