摘要
采用高温固相法制备锆掺杂钛酸锂负极材料,改变锆的掺杂量得到Li4Zr5xTi(5(1-x))O12(x=0.01,0.03,0.05)材料作为负极材料组装成电池,研究不同锆掺杂量对电池性能的影响,以期提高钛酸锂在高倍率下的放电比容量和循环容量保持率。
In this paper, a high-temperature solid-phase method was used to prepare zirconium-doped lithium titanate anode materials, and the doping amount of zirconium was changed to obtain materials: Li4Zr5xTi5(1-x)O12(x=0.01,0.03,0.05), which was used as anode materials to assemble the battery. The effect of different zirconium doping levels on battery performance was studied to improve the specific discharge capacity and cycle capacity retention rate of lithium titanate at high rates.
