摘要:
采用水浴法在ZIF67派生非晶C压缩多面体上生长MnO2纳米片材料,利用能量色散X射线光谱仪(EDS)、场发射扫描电子显微镜(FESEM)和透射电子显微镜(TEM)分析样品的物相组成和微观形貌,并作为负极材料制成锂电池,通过恒流充放电和循环伏安法研究该锂电池性能。研究结果表明:ZIF67派生非晶C多面体上成功生长了MnO2纳米片阵列,纳米片高约150 nm,厚约5~15 nm;在电流密度01 C时,非晶C多面体@MnO2纳米片阵列复合材料的首次放电比容量可达94460 mAh/g,200次循环后放电比容量依旧保持在62500 mAh/g,表明该复合材料具有较高的比容量和良好的循环性能。
