| 英文摘要 | Three different types of spherical cathodes (li[ni0.6co0.2mn0.2]o-2) were synthesized via hydroxide co-precipitation method coupled with high temperature lithiation process. the particle size, nanostructure, specific surface area and pore distributions can be controlled as expected. x-ray diffraction patterns revealed that the as-obtained cathode materials had a typical hexagonal alpha-nafeo2 layered structure with a space group r (3) over bar m. the electrochemical measurements demonstrate that li [ni0.6co0.2mn0.2]o-2 with 3 mu m-size in diameter exhibited higher initial coulombic efficiency (94.9%), rate capacity (156 ma h g(-1) at 900 ma g(-1)), and low-temperature property (157 ma h g(-1) at 180 ma g(-1), 0 degrees c ) in comparison with the larger one (12 mu m). most impressively, an ultra-stable capacity of 156 ma h g(-1) can be retained at 180 ma g-(1) even after 300 cycles at 0 degrees c. as is known, li[ni0.6co0.2mn0.2]o-2 with 3 mu m-size has the best result among the reported li[ni0.6co0.2mn0.2]o-2-based cathode materials. the excellent electrochemical performance of the smaller size cathode results from the advantageous hierarchical nanorods architecture, porous characteristics, and reduced ions/electrons transport path. |
