| 英文摘要 | Spinel li4ti5o12/c was synthesized by one-step solid-state reaction route using lithium polyacrylate (paali) as lithium and carbon sources, and tio2 as titanium source. the characteristics of li4ti5o12/c composites were determined by x-ray diffraction, scanning electron microscopy, transmission electron microscopy and thermogravimetric-differential thermal analysis methods. their electrochemical performances were investigated by cyclic voltammograms, constant current charge-discharge and rate charge-discharge. it was found that molecular weight of polyacrylic acid (paa), heating rate and sintering duration directly affected the physical and electrochemical performances of li4ti5o12/c composites. the li4ti5o12/c composites with the optimized electrochemical performances were obtained in the following conditions, i.e., paa with the molecular weight of 10,000, heating rate of 20 degrees c min(-1) and sintering duration of 8 h. at charge-discharge rate of 4 c and 8 c, the optimized sample showed discharge capacities of 148.4 and 142.4 mah g(-1), with capacity retention of 94.48 and 90.53% after 50 cycles, respectively. even at 20 c, its discharge capacity was 116.0 mah g(-1) with capacity retention of 87.61% after 50 cycles.
