摘要: The layered Li[Ni1/3Co1/3Mn1/3]O2 materials were synthesized by a spray pyrolysis method using citric acid as polymeric agent. powders characterized means of X-ray diffraction (XRD), charge/discharge cycling, cyclic voltammetry, and high-resolution transmission electron microscopy (TEM). discharge capacity increases linearly with the increase upper cut-off voltage limit. TEM analysis showed that particles in as-prepared powder possessed polycrystalline structure. During particle structure is mostly preserved although some surface grains on became separated transformed to spinel phase.
