2020年7月13日 · X-ray diffraction (XRD) characterizations were conducted by a Rigaku D/max-2550 diffractometer with Cu-Kα radiation, and Rietveld refinement was carried out for the...

2015年4月1日 · (d) XRD patterns of LLTO thin films prepared on STO, LAO and MgO substrates oriented along the (001) direction at 880 °C and under an oxygen pressure of 10 Pa. The XRD pattern for the films deposited at 880 °C shows well-defined peaks and, in the inset, the K α1 and K α2 contributions of the Cu source can be clearly identified revealing ...

To date, lithium lanthanum titanate (LLTO) of the nominal formula Li3xLa2/3-x1/3-2xTiO3 with perovskite structure have been considered to be promising solid electrolyte materials for...

We report on the ionic conductivity of Li0.33La0.55TiO3 (LLTO) epitaxial films grown on the (100) and (111) surfaces of single crystal SrTiO3 (STO) substrates at different oxygen partial...

2024年12月3日 · We show that LLTO perovskites can be cold sintered into composite electrolytes. Incorporating a lithium salt dissolved in a polymer matrix provides conductive pathways between grains, resulting in ionic conductivities comparable to those of conventionally sintered electrolytes.

2009年11月3日 · In this paper, spark plasma sintering was employed to prepare lithium lanthanum titanium oxide solid-state electrolyte. X-ray diffraction, scanning electron microscopy, X-ray photoelectron spectroscopy and electrochemical impedance spectroscopy were preformed to characterize their microstructure and ionic conductivity.

XRD analysis found that LLZTO300C40P remains crystallized in a single cubic with ionic conductivity of (3.02 0.53) x 10-5 Scm-1, which is higher than another result in Al doped-LLZO by CSP...

2017年9月10日 · The crystalline phase of the A-LLTO ceramic pellets was identified using X-ray diffraction (XRD; D/MAX Ultima III, Rigaku diffractometer with a Cu Kα radiation source). The microstructure of the ceramic samples was observed using field-emission scanning electron microscopy (FE-SEM; Hitachi S-4700).

2023年2月23日 · 在富Ni阴极晶体上构建钙钛矿Li 0.35 La 0.55 TiO 3 (LLTO)层，诱导产生层状@尖晶石@钙钛矿异质结构，以解决容量衰减的根本原因。原位X射线衍射技术和第一性原理计算表明，这种独特的异质结构不仅可以提高主体结构承受机械应变的能力，而且还为锂离子提供了快 …

2012年4月26日 · Li0.33La0.57TiO3 (LLTO) is a potential Li-ion conducting membrane for use in aqueous Li-air batteries. To be in this configuration its mechanical properties must be determined. Dense LLTO was prepared using a solid-state (SS) or sol–gel (SG) procedure and was hot-pressed to yield a high relative density material (>95 %).
