我们使用单晶到单晶的转换来直接成像,在二维亚稳插入材料中,主晶格的亚埃分辨率扭曲、Li位占用和扩散路径。我们捕获了锂离子扩散途径的原子描述,并通过二维嵌入主体重建了可用间隙位点的锂眼视图,以解决阴极材料设计中长期存在的挑战,并为原子精确的结构修饰铺平了道路。
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.
