abstract = {BackgroundAll-solid-state Li batteries (ASSLBs) are
emerging as potential electrochemical energy storage devices
for next-generation large-scale electrical power systems. In
particular, Li1.3Al0.3Ti1.7(PO4)3 (LATP) is an efficient
cost-effective solid-state electrolyte with high ionic
conductivity for high energy density and safety ASSLBs.
Since LATP is unstable verus metallic Li. Therefore, the
application of Li-based all-solid-state batteries is
practically limited.MethodsAs a possible solution to
overcome the LATP instability, the interface was modified by
adding a 5 nm thin ZnO layer on LATP using the atomic layer
deposition (ALD) technique.Significant FindingsThe ZnO layer
reduces the observed overpotential in a Li|ZnO@LATP|Li
symmetric cell compared to an unmodified LATP-based cell. In
contrast to the unmodified LATP-based Li cells, the
ZnO-modified symmetric LATP-based Li cells show stable
cycling for more than 500 h without a short circuit. The
full-cell configuration of the LiFePO4|ZnO@LATP|Li system
showed a reversible capacity of 156 mAh/g over 50 cycles and
exposed good capacity retention $(98.79\%$ after 50 cycles)
during the cycling test. The results indicate that ZnO
coating by ALD on LATP could overcome the stability issues
of pristine LATP versus metallic Li. Therefore, this work
will lead to prove the simple manner of interfacial
modification and improvement of electrochemical performance
of inorganic oxide based solid electrolytes for
all-solid-state lithium battery applications.},
