dc.description.abstract采用简单的水解、热处理方法合成三氧化二铁(Fe2O3)负载在三维多级孔类石墨烯(3D HPG)上的复合材料. 3D HPG有效的导电网络有利于负载纳米Fe2O3,使其呈均匀分散状态,并有效增强纳米复合物的导电率,提高Fe2O3利用率,抑制纳米Fe2O3的团聚,从而制得稳定、高性能的锂离子电池负极材料. Fe2O3-3D HPG电极在50 mA·g-1电流密度下首次放电容量达1745 mAh·g-1,50周期放电容量保持于1095 mAh·g-1.zh_CN
dc.description.abstractFerric oxide (Fe2O3) as a promising anode material for lithium ion battery is due to its high theoretical capacity (1007 mAh·g-1), earth abundance and low cost. The nanosized Fe2O3 on the three dimensional hierarchical porous graphene-like network (denoted as Fe2O3-3D HPG) has been synthesized by homogeneous precipitation and heat treatment. The 3D HPG can provide a highly conductive structure in conjunction to support well contacted Fe2O3 nanoparticles, and effectively enhance the mechanical strength of the matrices during volume changes, as well as improve the utilization rate of Fe2O3 and suppress the aggregation of Fe2O3 nanoparticles during Li ion insertion/extraction. As a result, the first discharge capacity of Fe2O3-3D HPG was up to 1745 mAh·g-1 at 50 mA·g-1, and after 50 cycles, the retention of the capacity was 1095 mAh·g-1.zh_CN
