We have developed an electrochemical cell having diamond plate windows for the in-situ synchrotron X-ray diffraction experiment during Li-ion charge-discharge processes. Using the developed cell, we have investigated structural changes of singlewalled carbon nanotubes(SWCNTs) and TiO2 electrodes with Li-ion insertion/extraction. It was found that diffractions of SWCNTs lose their intensities just by immersing SWCNTs in electrolyte. On the other hand, we could observe the change in XRD pattern of Ti02(B) phase with increasing/decreasing Li content. The structures of Ti02(B) phase during Li-ion chargedischarge process were elucidated by Rietveld analyses of the obtained XRD patterns

我们研制了一种具有金刚石板窗的电化学电池，用于锂离子充放电过程的原位同步加速器x射线衍射实验。利用所制备的电池，我们研究了锂离子插入/提取时单壁碳纳米管（SWCNTs）和TiO2电极的结构变化。研究发现，仅仅将SWCNTs浸泡在电解质中，其衍射就会失去其强度。另一方面，我们可以观察到tio2 (B)相的XRD谱图随Li含量的增加和减少而变化。通过XRD谱图的Rietveld分析，阐明了锂离子充放电过程中tio2 (B)相结构
