摘要

The nickel-rich LiNi_0.7Co_0.15Mn_0.15O₂ material was sintered by Li source with the Ni_0.7Co_0.15Mn_0.15(OH)₂ precursor, which was prepared via hydrothermal treatment after coprecipitation. The intensity ratio of I₍₁₁₀₎/I₍₁₀₈₎ obtained from X-ray diffraction patterns and high-resolution transmission electronmicroscopy confirm that the particles have enhanced growth of (110), (100), and (010) surface planes, which supply superior inherent Li⁺ deintercalation/intercalation. The electrochemical measurement shows that the LiNi_0.7Co_0.15Mn_0.15O₂ material has high cycling stability and rate capability, along with fast charge and discharge ability. Li⁺ diffusion coefficient at the oxidation peaks obtained by cyclic voltammogram measurement is as large as 10^-11 (cm² s^-1) orders of magnitude, implying that the nickel-rich material has high Li⁺ diffusion capability.
