我们用实验室衍射仪对LiFePO4在装有Kapton窗的硬币电池中进行电化学循环过程中的X射线衍射进行了研究。所得结果与前人的研究结果一致，验证了从LiFePO4中提取Li遵循双相固溶体行为，在脱嵌过程中LiFePO4和FePO4都不保持静态成分。
We have used a laboratory diffractometer to performoperandoX-ray diffraction on LiFePO4during electrochemical cycling in a coin cell fitted with a Kapton window. The results obtained are in good agreement with previous studies, verifying that extraction of Li from LiFePO4follows dual-phase solid solution behaviour, with neither LiFePO4nor FePO4maintaining a static composition during deintercalation.
