摘要：
Ni0.6Co0.2Mn0.2(OH)(2) with unique morphology of dispersed hexagonal slab particles is synthesized via the hydrothermal method, which reacts with lithium hydroxide to form single-crystalline LiNi0.6Co0.2Mn0.2O2 (SC-NCM) after a simple sintering process. Scanning electron microscopy, X-ray diffraction and transmission electron microscopy testify the micrometer-sized SC-NCM particles display well-ordered layered structure with excellent crystallinity. Electrochemical characterization demonstrates that the LiNi0.6Co0.2Mn0.2O2 sample performs excellent capacity retentions of 93.2% (2.8-4.3 V) and 89.6% (2.8-4.5 V) after 100 cycles at a current rate of 1 C. In particular, LiNi0.6Co0.2Mn0.2O2 displays extraordinary rate property (174.5 mAh g(-1) at 0.1 C and 130.7 mAh g(-1) at 5 C). Therefore, it may provide a new method for the preparation of single crystalline LiNixCoyMnzO2 materials with superior electrochemical performance. (C) 2021 Elsevier B.V. All rights reserved.
