A facile lithium redistribution that occurs between interconnected active particles indicates that lithium does not necessarily become isolated in individual particles due to loss of a direct contact. Our results have implications for the design of all-solid-state battery electrodes with improved capacity retention and cyclability. © Subject (de)lithiationall-solid-state batterieselectrode-electrolyte interfaceelectron microscopyoperando TEM To reference this document use: http://resolver.tudelft.nl/uuid:a6cc796e-012c-4dd9-98f4-6bfda227c1da DOI https://doi.org/10.1021/acsaem.0c00543 ISSN 2574-0962 Source ACS Applied Energy Materials, 3 (6), 5101-5106 Part of collection Institutional Repository Document type journal article Rights © 2020 S.
