Microstructure and strain characterizations of battery samples.

First, I would like to measure the XRD pattenrs of raw lithium and sodium. These metals will encapsulated in an inert atmosphere (in a capillary) and will be present in sub-millimitric volumes. Then, I want to characterize the microstructure and strain of a solid electrolyte for sodium (NaGdSiO). Finally, I want to charecterize the microstructure + strain of an other sample that is made of previously cycled cathode grains (LCO-NMC).

首先，对原始锂与钠开展X射线衍射（XRD）图谱测试。待测金属样品将封装于惰性气氛的毛细管中，样品体积为亚毫米级。其次，针对钠基固体电解质（NaGdSiO）的微观结构与应变进行表征。最后，对另一组由经预循环正极颗粒（LCO-NMC）制备得到的样品开展微观结构与应变表征。
