用VGCF为模板,用共沉淀方法辅助合成了棒状结构的LiNi1/3Co1/3Mn1/3O2。通过X-射线衍射仪(XRD)、X射线能谱仪(EDX)、扫描电子显微镜(SEM)对其结构进行了表征,并研究了其电化学性能。结果表明:该材料为棒状且表面多孔,并表现出了良好的电化学性能。在0. 2 C(1 C=170 m A/g)的电流密度下,其容量为160 m Ah/g以上,在1 C下经过250个循环后容量仍然有115. 2 m Ah/g,对于制备其他棒状结构的锂离子正极材料提供了一定的借鉴。
摘要(英文)：
LiNi1/3 Co1/3 Mn1/3 O2 with rod structure was synthesized by co-precipitation method with VGCF as template. The structure was characterized by X-ray diffraction( XRD),X-ray energy spectroscopy( EDX) and scanning electron microscopy( SEM),and its electrochemical properties were studied. The results showed that the material had porous rod-shaped structure,and exhibited good electrochemical performance. LiNi1/3 Co1/3 Mn1/3 O2 cathode delivered a capacity of 160 m Ah/g at 0. 2 C( 1 C = 170 m A/g),and the capacity still remained 115. 2 m Ah/g at 1 C after 250 cycles. It could provide a reference fo...
