We use single-crystal-to-single-crystal transformations to directly image with sub-angstrom resolution distortions of the host lattice, Li site occupancies, and diffusion pathways in a 2D metastable intercalation material. We capture atomistic descriptions of Li-ion diffusion pathways and reconstruct a Li-eye view of available interstitial sites through a 2D intercalation host to address a long-standing challenge in the design of cathode materials and pave the way to atom-precise structural modifications.

来自拓扑化学单晶转变的二维插层材料中扩散路径的“Li-Eye”视图

我们使用单晶到单晶的转换来直接成像二维亚稳态插层材料中主晶格的亚埃分辨率畸变、Li 位点占据和扩散路径。我们捕获了锂离子扩散路径的原子描述，并通过二维嵌入主体重建了可用间隙位点的 Li-eye 视图，以解决正极材料设计中长期存在的挑战，并为原子精确的结构修改铺平道路。
