The x-ray diffraction (XRD) peaks in Fig. 1A provide immediate information about the composition of LiAl alloy. The XRD pattern indicates that Li and the Li 9 Al 4 intermetallic compound are the dominant species present and that the crystal structures correspond to Li …

2022年4月13日 · In situ x-ray diffraction (XRD) was adopted to investigate the lithiation process of Al and unveiled a two-phase reaction with modest volume change. The appropriate operating potential and temperate volume change of Li-Al alloy resulted in its excellent stability toward LGPS, as proven by the electrochemical test of symmetric cells and ...

The x-ray diffraction (XRD) peaks in Fig. 1A provide immediate information about the composition of LiAl alloy. The XRD pattern indicates that Li and the Li 9 Al 4 intermetallic...

2022年9月1日 · The LiAl-LDHs were characterized by Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and porosity. Special attention was focused on the rise of Li+ adsorption capacity based on the porous morphology in synthetic and real salt lake brine.

2001年10月30日 · The combination of XRD, TG/DSC, and compositional analysis with 27Al, 6Li, 7Li, and 35Cl NMR spectroscopy at a high field (H0 = 17.6 T) provides a comprehensive picture of the phase formation, phas...

图2C为LiAl合金电极的原位XRD图谱，从图中可以看出，随着锂化过程，LiAl峰逐渐出现，且强度逐渐增加，与Al峰共存直至结束。 表明，Li0.8Al合金是Al和LiAl的两相混合物，Al:LiAl = 1:4。

2019年6月30日 · We will present ex- and in-situ (variable temperature cycling, room temperature XRD, with and without cell disassembly) and in-operando (integrated variable temperature cycling and XRD, without cooling) results from aluminum thin films and (much thicker, but still thin) aluminum foils to map out phase formation as a function of temperature, samp...

2018年8月6日 · In our recent study 16, a nanocomposite LiAl-LDH@201 with enhanced stability (over pH 3.5–12) and improved fluoride removal capacity was developed by impregnating Li/Al LDHs into a millimetric...

X射线衍射（XRD），傅立叶变换红外光谱（FTIR），扫描电子显微镜（SEM）和透射电子显微镜（TEM）表征显示了Li Al HTlc的相互连接的花状层状结构。 在给定的吸附剂浓度（C s）下，Cu 2+ 和Zn 2+ 在Li Al HTlc上的吸附动力学和等温线分别与拟二级模型和Langmuir模型一致。 该 ç 观察到 s 对吸附动力学和等温线的影响，Langmuir-表面组分活度（SCA）方程可用于表征 C s 在吸附等温线中的作用。 吸附过程是自发的，并且是吸热的。 吸附机理表明吸附过程是通过两种 …

研究了铝酸锂（LiAlO 2）粉末在700℃还原（4％H 2 N 2）和氧化（空气）气氛下的稳定性。XRD结果显示原始的α- LiAlO 2样品包含少量LiAl 2（OH）7 ·2H 2 O和LiAlO 2 ·0.25H 2 O相，而高温XRD研究表明LiAl 2（OH）7 · 2H 2 O在700°C时可能分解为γ- LiAlO 2和LiAlO 2 ·0.25H 2 O分解 …
