The molten phase of transition metal and lithium salts self-assemble with non-ionic surfactants to form lyotropic liquid crystalline (LLC) mesophases, which are important in the development of gel-electrolytes and mesoporous materials. Here, we show that LiH PO forms a semi-stable LLC mesophase with 10-lauryl ether (C H (OCH CH ) OH, C E ), decoded as Li-EO-X (X is LiH PO /C E mole ratio and between 2 and 200). The stability of the Li-EO-X phase is improved by increasing salt concentration (X>20) in the media. The semi-stable Li-EO-X mesophase is further stabilized by adding either water by controlling the humidity or H PO (PA) to the media. The phase behaviour of the above samples was investigated using POM, XRD, conductivity, and ATR-FTIR measurements. The addition of PA not only brings stability and higher conductivity (increase from 0.1 to 8.9 mS/cm) to the mesophase but also produce an LLC gel-electrolyte with a high buffer capacity that may be useful and important in various applications.
过渡金属和锂盐的熔融相与非离子表面活性剂自组装形成溶致液晶（LLC）中间相，这在凝胶电解质和中孔材料的发展中很重要。在这里，我们表明 LiHPO 与 10-月桂醚（C12H24O(C2H4O)nOH，C10E）形成半稳定 LLC 中间相，解析为 Li-EO-X（X 是 LiHPO/C10E 的摩尔比，在 2 到 200 之间）。通过增加介质中的盐浓度（X>20）可以提高 Li-EO-X 相的稳定性。通过控制湿度向介质中添加水或 H3PO4（PA）可以进一步稳定半稳定的 Li-EO-X 中间相。使用 POM、XRD、电导率和 ATR-FTIR 测量研究了上述样品的相行为。PA 的添加不仅为中间相带来了稳定性和更高的电导率（从 0.1 增加到 8.9 mS/cm），而且还产生了具有高缓冲能力的 LLC 凝胶电解质，这在各种应用中可能是有用和重要的。
