在上篇《锂离子电池电极材料的晶相分析（一）》中我们讲到锂离子电池中的电极是使用由悬浮在粘结剂溶液中的活性电极颗粒和导电添加剂多组分浆料涂覆在金属箔基材上制成的，它对电池的电化学性能有着决定性的影响。 我们可以通过晶相组成和晶粒大小等参数可以描述电极材料的晶相特征和晶相组成（例如NCM正极材料中的Ni浓度），继而掌握控制充放电循环过程中的能量密度和材料稳定性。

锂离子电池中使用的电极对其电化学性能有着决定性的影响，通常是使用由悬浮在粘结剂溶液中的活性电极颗粒和导电添加剂制成的多组分浆料涂覆在金属箔基材上制成的。电极材料的原级颗粒粒度和晶相在锂离子的扩散方面发挥着重要作用，并影响离子迁移速率和电池再充电时间等关键电池性能参数。我们可以通过晶相组成和晶粒大小等参数广泛地描述晶相的特征。 X射线衍射 (XRD) 是用于分析晶相属性，从而分析合成粉末材料质量的常用技术。它可以测量相纯度、相组成和晶粒大小。使用 XRD 的晶相分析也可用于推导石墨化度或石墨阳极材料中的取向指数等参数。

IntroductionLiposomes are spherical-shaped vesicles composed of one or more phospholipid bilayers. They are often used as drug delivery vehicles for the administration of pharmaceutical drugs and nutrients; as such, it is essential that their size distribution is well characterized for manufacturing and batch release. Nanoparticle Tracking Analysis (NTA) is a powerful technique for the high-resolution ...

Introduction More control: that is the response to the solution to increasingly complex requirements. Most cement companies have adopted the goal of net-zero carbon emissions – and these goals, in combination with energy costs, quality requirements, emissions and other sustainability concerns, are driving the need for increasingly tighter control over production processes. Malvern Panalytical ...
