Herein, the lithium-rich material Li[Li0.2Mn0.56Ni0.16Co0.08]O2 is successfully prepared by a sucrose-assisted gel method. With the assistance of sucrose, Li[Li0.2Mn0.56Ni0.16Co0.08]O2 precursors can be uniformly dispersed into sticky sucrose gel without aggregation. XRD shows that the lithium-rich material Li[Li0.2Mn0.56Ni0.16Co0.08]O2 has a well-organized layered structure. The electrochemical performance is influenced by calcination temperature. The results show that the sample Li[Li0.2Mn0.56Ni0.16Co0.08]O2 calcined at 900 °C possess significant performance. This sample delivers higher discharge specific capacity of 252 mAh g−1; rate capability with a capacity retention of 86% when tested at 5C; and excellent cyclic stability with a capacity retention rate of 81% after 100 cycles under 1C test. The sucrose-assisted method shows great potential in fabricating layered lithium-rich materials. View Full-Text
