固体聚合物电解质（SPE）是解决锂电池安全问题的最有前途的解决方案之一。了解形态和动力学对SPE离子传输性能的影响将是未来SPE设计的关键。在这篇文章中，以聚（环氧乙烷）（PEO）为例，我们专注于半结晶SPE的形态控制。我们表明，半连续性的影响可以定量地分为体积，结构和动力学效应。我们进一步表明，形态控制起着重要的作用，在半结晶SPE系统中的离子传输控制。
Solid polymer electrolytes (SPEs) are one of the most promising solutions to the safety issues of lithium batteries. Understanding the morphology and dynamic effects on the ion transport properties of SPEs would be essential for future SPE design. In this article, using poly(ethylene oxide) (PEO) as an example, we focus on morphology control in semicrystalline SPEs. We show that the effect of semicrystallinity can be quantitatively separated into volume, structure and dynamic effects. We further demonstrate that morphological control plays an important role in ion transport control in semicrystalline SPE systems.
