在优化的制备条件下，通过超临界水合成（SCWS）获得了LiCoO2单晶颗粒。反应时间小于1分钟。 LiCoO2粒径<1μm，远小于固相反应制备的LiCoO2，且LiCoO2晶型为菱面体。电子衍射图像显示出高度结晶的 LiCoO2 相。锂在 LiCoO2 颗粒中的嵌入和脱嵌均具有良好的可逆性。© 2000 The Electrochemical Society。 S1099-0062 (00) 01-052-X。版权所有。
LiCoO2 single-crystal particles were obtained by supercritical water synthesis (SCWS) under optimized preparation conditions. The reaction time was less than 1 min. The LiCoO2 particle size was< 1 µm, which was much smaller than that of LiCoO2 prepared by a solid-state reaction, and the LiCoO2 crystal shape was rhombohedral. An electron diffraction image showed a highly crystalline LiCoO2 phase. Intercalation and deintercalation of lithium into and from LiCoO2 particles were carried out with good reversibility.© 2000 The Electrochemical Society. S1099-0062 (00) 01-052-X. All rights reserved.
