Preparation of LiCoMnO4 Assisted by Hydrothermal Approach and its Electrochemical Performance Meilin You, Xingkang Huang, Min Lin, Qingsong Tong, Xiuhua Li, Ying Ruan and Yong Yang DOI : 10.3844/ajeassp.2016.396.405 American Journal of Engineering and Applied Sciences Volume 9, Issue 2 Pages 396-405 Abstract LiCoMnO4 materials have been synthesized via a hydrothermal approach followed by a post-annealing process. Pure phase of LiCoMnO4 is unable to form under hydrothermal conditions; however, high quality of pure LiCoMnO4 was achieved after annealing the hydrothermal products. The concentration of LiOH and the post-annealing temperature are the crucial factors to form LiCoMnO4. Without post-annealing process, the highest contents of LiCoMnO4 in the hydrothermal products are less than 50% (e.g., in the presence of 1.2-1.35 M LiOH); in contrast, in the cases of 1.35-1.4 M LiOH, almost pure phase of LiCoMnO4 has been achieved successfully after annealing the hydrothermal precursors at 750°C. The as-prepared sample in the presence of 1.35 M LiOH, after annealed at 750°C, exhibits a capacity of 91.6 mAh g-1.
