abstract = {Solid-state lithium-metal batteries (SSLMBs) with a
composite solid electrolyte (CSE) have great potential
forachieving both high energy density and high safety and
are thus promising next-generation energy storagedevices.
The current bottlenecks are a high electrode/electrolyte
interface resistance and the limited Li+conductivity of the
solid electrolyte layer. To reduce the interface resistance,
a tape casting method isused to directly deposit a CSE layer
(20 mm) onto a model LiFePO4 cathode. The CSE slurry
infiltratesthe cathode layer, forming a Li+ conduction
network and ensuring intimate contact between the CSEand the
cathode. The tape casting parameters, such as the polymer/Li
salt ratio, inorganic filler fraction,and casting thickness,
for the CSE layer are investigated. To increase Li+
conductivity, Ce substitution isconducted for Li7
La3Zr2−xCexO 12, x ¼ 0–0.15. The effects of Ce content
on the specific capacity, ratecapability, and cycling
stability of Li//CSE//LiFePO4 cells are systematically
studied. Li 7 La3Zr1.9 Ce0.1O 12(i.e., x ¼ 0.1) is found to
be the optimal composition; it outperforms Li7 La3Zr2O 12
andLi 6.25Ga0.25 La3Zr2O12 in terms of CSE conductivity and
SSLMB charge–discharge performance.},
