Abstract
Polymeric
materials
featuring
excellent
flame
retardancy
are
essential
for
applications
requiring
high
levels
of
fire
safety,
while
those
based
on
biopolymers
highly
favored
due
to
their
eco‐friendly
nature,
sustainable
characteristics,
and
abundant
availability.

such
as

Covalent
organic
frameworks
(COFs),
featuring
structural

porosity,
and
functional
versatility,
have
emerged
as
promising
electrode
materials
for

batteries.
To
date,
amorphous

COF,
or
their
composites
are
mostly
explored
in
lithium-ion
batteries
(LIBs),
while
research

is
still
infancy.
This
can
be
due
to
the
challenges
that
arise
from
large
