Imperfections in energy materials

Witryna15 wrz 2024 · In this paper, we present an overview of crystal imperfections in ice I h. Due to its molecular nature, the fundamental asymmetry of the hydrogen bond, and proton disorder, crystal defects in this condensed form of water reveal a complexity not usually seen in atomic crystalline solids. WitrynaThis investigation reveals that the formation of lithium whiskers is decided by the local Li ion flux and the deposition active sites, which are closely dependent on the content and types of defects in the polycrystalline electrolyte. Moreover, the defect regions exhibit faster Li deposition kinetics and higher nucleation tendency.

WitrynaCrystal imperfections can be divided into four basic types based on type of defect and its dimensionality. They are point defects (0-dimensional), line defects (1-dimensional), surface defects (2-dimensional) and volume defects (3-dimensional). Figure 4.2 shows a broad classification system for crystal imperfections. WitrynaAtomic scale imperfections, know as point defects, dictate the performance and efficiency of many modern energy materials. The challenges of climate change require the continued improvement and identification of materials which can have point defects engineered in a favorable fashion for the application of interest.
