| 摘 要： | 由电池挤压试验机得到不同荷电状态的电池爆喷失效后的残留粉末.经称量、水溶解和X射线衍射(XRD)测试,结果表明,随着电池荷电状态的提高,单位能量升高,电池燃烧温度上升和持续时间延长,其铜箔完好程度逐渐降低,粉末残余量逐渐减少.依据水溶解实验可将残留粉末分为不溶粉末和可溶粉末2种,其中不溶粉末较多,主要成分有C、Co和CoO;可溶粉末较少,主要成分有Li2CO3和LiF.随着电池荷电状态的提高,不溶粉末含量逐渐减少,而可溶粉末含量逐渐增多.

| Abstract: | The residual powders of lithium-ion batteries at different voltages after explosion were obtained by using the battery impact testing machine.And these powders have been investigated by weighing,water solution and X-ray diffraction(XRD).The results showed that the integrity status of copper current collector and weight of residual powders decreased gradually with increasing of battery voltage,rising of burning temperature and releasing of burning duration time.The residual powders could be separated to inso... |
