Abstract:
Dynamic and direct visualization of interfacial evolution is helpful in
gaining fundamental knowledge of all-solid-state-lithium battery
working/degradation mechanisms and clarifying future research
directions for constructing next-generation batteries. Herein, in situ
and in operando synchrotron X-ray tomography and energy dispersive
diffraction were simultaneously employed to record the morphological
and compositional evolution of the interface of InLi-anode|sulfidesolid-
electrolyte during battery cycling. Compelling morphological
evidence of interfacial degradation during all-solid-state-lithium
battery operation has been directly visualized by tomographic
measurement. The accompanying energy dispersive diffraction results
agree well with the observed morphological deterioration and
the recorded electrochemical performance. It is concluded from the
current investigation that a fundamental understanding of the
phenomena occurring at the solid–solid electrode|electrolyte interface
during all-solid-state-lithium battery cycling is critical for future
progress in cell performance improvement andmay determine its final
commercial viability.
