Dynamic imaging of lithium in solid-state batteries by operando electron energy-loss spectroscopy with sparse coding

摘要

Schematic of the SSLIB used in this study. The red dashed rectangle shows the thinned area for TEM observation. Charge and discharge curves of the thinned SSLIB sample operated in the transmission electron microscope. Cross-sectional ADF-STEM image around the interface between LiCoO and LASGTP. Phases and Li concentration in the LiCoO cathode film investigated in our previous study . Reprinted with permission from ref. . Copyright (2018) American Chemical Society. The scale bars in and are 200 and 50 nm, respectively.
