Indirect state-of-charge determination of all-solid-state battery cells by X-ray diffraction

Chemical communications 55(75), 11223 - 11226 (2019). doi:10.1039/C9CC04453A
Determining the state-of-charge of all-solid-state batteries via bothex situ and operando X-ray diffraction, rather than by electrochemicaltesting (may be strongly affected by electrically isolated/inactivematerial, irreversible side reactions, etc.), is reported. Specifically,we focus on bulk-type cells and use X-ray diffraction data obtainedon a liquid electrolyte-based Li-ion cell as the reference standardfor changes in lattice parameters with (de)lithiation.
