For
normal
AGM
battery,
there
is
certain
porous
ratio
inside
AGM
(micro
porous
adsorptive
glass
mad)
separator.
Thus
there
is
a
path
existing
between
the
positive
and
the
negative.
Also
special
alloy
grid
is
chosen
to
increase
vent
hydrogen
over
‐
potential
gassing
on
the
negative
plates,
which
prevent
generation
of
Hydrogen.
Otherwise,
the
oxygen
generated
from
positive
diffuses
through
separator
to
the
negative
and
the
oxygen
gas
reacts
quickly
and
is
recombined
into
water.
For
Gel
battery,
we
adopt
gel
electrolyte
and
PVC
‐
SiO
2
Separator
to
set
up
oxygen
cycle
principle:
Battery
is
full
of
gel
electrolyte
inside,
and
A

‐
D
porous
network
is
formed
with
framework
of
SiO
2.
The
net
contains
electrolyte
necessary
for
battery.
At
initial
stage,
the
construction
is
not
steady.
As
time
goes
on,
the
framework
is
shrink
and
some
cracks
appeared
in
the
gel.
The
cracks
exist
between
pos.&
neg.
plates
and
separator
and
become
a
path
between
the
positive
and
the
negative.
Thus
it
is
possible
to
build
GEL
battery
in
sealed
structure.
