Energizer
Zinc
Air
Prismatic
batteries
are
designed
to
allow
air
to
enter
the
air
holes
and
to
prevent
the
transport
of
liquid
electrolyte
out
of
the
battery.
A
gasket
is
used
to
seal
between
the
anode
cup
and
the
cathode
can.
The
gasket
also
electrically
insulates
the
negative
cup
from
the
positive
can.
An
air
electrode
and
a
loose
layer
of
Teflon
are
compressed
onto
a
band
of
sealant
on
the
bottom
of
the
can.
This
Teflon
layer
allows
gasses
to
enter
the
battery
while
preventing
liquid
from
passing
through.

Features
of
Zinc
Air
Prismatic
Energizer’s
Zinc
Air
Prismatic
batteries
offer
a
5
mm
thin,
prismatic
construction
designed
to
work
with
a
variety
of
applications.
This
shape
is
consistent
with
the
low
profile
design
of
today’s
devices,
often
requiring
a
thinner
battery
solution.
The
thinnest
round
cell
available
is
the
AAAA
battery
at
approximately
8
mm,
and
many
Lithium
Ion
rechargeable
solutions
have
a
thickness
of
5
mm.
Energizer
Zinc
Air
Prismatic
batteries
also
offer
the
opportunity
to
significantly
lower
manufacturer
costs.
It
is
likely
that
the
cost
of
a
Zinc
Air
Prismatic
battery
solution
will
be
less
than
the
cost
of
a
Lithium
Ion
battery.
Adding
to
the
cost
of
a
Lithium
Ion
solution
is
the
cost
of
circuitry
for
charge
and
discharge
control,
which
is
not
needed
with
Zinc
Air
Prismatic
batteries.
Furthermore
Zinc
Air
Prismatic
batteries
are
ready
to
be
used
out
of
the
package.
There
is
no
need
for
charge
adaptors.
Energizer
Zinc
Air
Prismatic
batteries
can
last
up
to
3X
longer
than
comparable
volume
battery
systems.
This
service
advantage
is
due
to
Zinc
Air
technology
offering
the
highest
energy
density
for
non
‐
rechargeable
and
rechargeable
consumer
batteries.
Figure

demonstrates
this
advantage
over
Alkaline
and
Lithium
Ion
batteries
of
similar
volume.
