2013年3月26日 · In this study, we examine structural and surface compositional changes of Li 2 O 2 and Li 2 O upon heating via in situ XRD and XPS techniques. In situ XRD reveals that the c/a ratio of the hexagonal unit cell of Li 2 O 2 decreases …

2023年2月2日 · By using a composite polymer electrolyte based on Li 10 GeP 2 S 12 nanoparticles embedded in a modified polyethylene oxide polymer matrix, we found that Li 2 O is the main product in a room temperature solid-state lithium-air battery. The battery is rechargeable for 1000 cycles with a low polarization gap and can operate at high rates.

同时PC-LCE SEI的XRD精修（图1b）揭示了三个晶相的共存：Li、Li2O和LiH，暗示着死锂（Li0）的形成。 其中，Li2O已被其他技术所鉴定，并被认为是盐和溶剂的分解产物。

2013年3月26日 · The changes in the crystal structure and surface chemistry of Li 2 O 2 and Li 2 O were examined as a function of temperature via in situ X-ray diffraction (XRD) and in situ X-ray photoelectron spectroscopy (XPS). Significant decreases in the lattice parameters and the c / a ratio of Li 2 O 2 were found at 280°C and higher.
