| 摘 要： | 通过水热合成法制备羟基磷灰石[Ca5(PO4)3(OH)]纳米线(HN),并与多壁碳纳米管(MWCNTs)导电纸形成层次交联的新型羟基磷灰石纳米线复合(HN/CNT)夹层.利用扫描电子显微电镜、傅里叶变换红外光谱(FTIR)和紫外-可见光谱(UV-Vis)等对材料的形貌与结构进行表征.电化学测试结果表明,含HN/CNT夹层的锂硫电池在1C倍率下循环200次后放电比容量仍保持在871 mA·h/g,每次循环衰减率仅为0.031%.

| Abstract: | Hydroxyapatite[Ca5(PO4)3(OH)] nanowires were prepared by hydrothermal synthesis, and were combined as a polysulfide absorbent with multi-walled carbon nanotubes(MWCNTs) interlayer to form a hierarchically cross-linked hydroxyphosphate nanowire composite(HN/CNT) interlayer. This layer was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy(FTIR)and ultraviolet-visible spectroscopy(UV-Vis). The results of electrochemical tests show that the Li-S battery with HN/CNT interlayer has a specific discharge capacity of 871 mA·h/g after 200 cycles at 1C, and the fading rate is only 0.031% per cycle. |
