摘要
针对共享车位监视系统备用电池的需求,提出了一种新型的锂离子电池负极材料的制备方法。以TiO_2纳米纺锤作为基体材料,制备了C-TiO_2@Co_3O_4纳米复合物,循环100周后可逆容量保持450m Ah/g仍远高于商业化碳材料,首次放电容量和充电容量分别为930和722 mAh/g,对应库伦效率为77.6%。优异的性能决定其可应用于车位监视系统备用电池的制造。
A new type of lithium ion battery anode material preparation method is proposed for the needs of the battery backup system of the shared parking space monitoring system. The nanocomposites of C-TiO2@Co3O4 were prepared with TiO2 nanospindle as the matrix material. The reversible capacity of 450 mAh/g after 100 weeks of circulation was still much higher than that of commercial carbon materials. The initial discharge capacity and charge capacity were 930 and 722 mAh/g, and the corresponding Coulombic efficiency is 77.6%. It can be used in the manufacture of spare batteries for parking surveillance systems for it＇ s excellent performance.
