abstract = {Thin, fast-conducting and mechanically robust separators
are expected to be advantageous in enabling all-solid-state
batteries with high energy densities and good
electrochemical performance. In this study, a potentially
new scalable fabrication route for flexible
thiophosphate–polymer separator membranes is demonstrated.
By infiltrating a commercially available polymer mesh with
the highly conductive inorganic solid ion conductor
$Li_{5.5}PS_{4.5}Cl_{1.5}$, a hybrid separator membrane with
a high ionic conductivity is realized. The electrochemical
evaluation via rate capability tests reveals superior
performance at low stack pressures and high C-rates, when
comparing cells employing the hybrid membrane separator, to
cells utilizing conventional solid electrolyte separators.
As a proof of concept, a full cell implementing the hybrid
membrane between a Si-based anode and a
$LiNi_{0.83}Co_{0.11}Mn_{0.06}O_2–Li_{5.5}PS_{4.5}Cl_{1.5}$
composite cathode is evaluated. The experimental work is
complemented by resistor network modelling of the hybrid
membrane sheets, shedding light on potential challenges in
cell operation.},
