Solid-state
sodium

batteries
are
among
the
most
promising
next-generation
energy
storage
devices.
However,
developing
competent
solid-state
electrolytes
for
these
remains
a
significant
challenge.
Herein,
we
introduce
design
quasi-solid-state
polymer
electrolyte
that
enhances
battery
performance.
This
multicomponent
electrolyte,
designated
PH-MSN-HNT,
was
synthesized
by
incorporating
modified
MOF
particles
and
halloysite
nanotubes
(HNTs)
into
PVDF-HFP
(PH)
matrix.
Due
to
synergistic
effects
of
components,
PH-MSN-HNT
exhibits
