摘 要: 利用石墨和钛酸锂复合材料作为锂离子电池的阳极活性材料,与磷酸铁锂阴极材料匹配制备了锂离子电池。制作的电池分别在充电曲线和放电曲线上出现两个平台,特别是第二个放电平台的出现,有助于降低过放对电池性能的影响。 Li-ion battery with graphite-Li4Ti5O12 composite anode and LiFePO4 cathode was fabricated. There were two charge platforms in the charge curve and two discharge platforms in the discharge curve, respectively. It was noticed that the second discharge platform could protect the battery from overdischarge.
