abstract = {With the ever-increasing use of Li-ion batteries,
especially due to their adoption in electric vehicles, their
safety is in prime focus. Thus, the all-solid-state
batteries (ASSBs) that use solid electrolytes instead of
liquid electrolytes, which reduce the risk of flammability,
have been the center stage of battery research for the last
few years. However, in the ASSB, the ion transportation
through the solid-solid electrolyte-electrode interface
poses a challenge due to contact and
chemical/electrochemical stability issues. Applying a
suitable coating around the electrode and/or electrolyte
particles offers a convenient solution, leading to better
performance. For this, researchers are screening potential
electronic/ionic conductive and nonconductive coatings to
find the best coatings with suitable thickness for long-term
chemical, electrochemical, and mechanical stability.
Operando transmission electron microscopy (TEM) couples high
spatial resolution with high temporal resolution to allow
visualization of dynamic processes, and thus is an ideal
tool to evaluate electrode/electrolyte coatings via studying
(de)lithiation at a single particle level in real-time.
However, the accumulated electron dose during a typical
high-resolution in situ work may affect the electrochemical
pathways, evaluation of which can be time-consuming. The
current protocol presents an alternative procedure in which
the potential coatings are applied on Si nanoparticles and
are subjected to (de)lithiation during operando TEM
experiments. The high volume changes of Si nanoparticles
during (de)lithiation allow monitoring of the coating
behavior at a relatively low magnification. Thus, the whole
process is very electron-dose efficient and offers quick
screening of potential coatings.},
