摘要

以二氧化锰、硝酸镍、碳酸锂为原料,采用固相法工艺合成了镍锰酸锂(LiNi_0.5Mn_1.5O₄)正极材料,采用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对在不同焙烧温度、不同焙烧时间下制得的LiNi_0.5Mn_1.5O₄进行了表征。结果表明,900℃焙烧10h制得的LiNi_0.5Mn_1.5O₄的粒径约1μm,晶体结构完整,呈现规则的多面体形貌。

Abstract

Lithium nickel manganese oxide (LiNi_0.5Mn_1.5O₄) anode material was synthesized by solid phase method,using manganese dioxide,nickel nitrate and lithium carbonate as raw materials.X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to characterize the morphology and structure of LiNi_0.5Mn_1.5O₄ prepared under different calcination temperature and calcination time.The results showed that the as-prepared LiNi_0.5Mn_1.5O₄ samples were spinal crystals.The crystal structure of LiNi_0.5Mn_1.5O₄ calcinating at 900℃ for 10h was about 1μm complete crystal and the sample morphology was a regular polyhedron.
