Batteries, Chargers, and
Power Supplies, Custom and
off-the-shelf.
PowerStream
has been working with a team of
engineers in China to develop the
thinnest possible lithium polymer
batteries. We can now offer design
engineers batteries of 1.0 mm to 0.5 mm
thick. These cells should be useful for
smart cards, RFID tags and other
applications that require energy
storage in a very thin battery.
Lithium ion cells are used in a
wide variety of portable equipment and
instruments. Lithium polymer cells have
a better form factor than cylindrical
cells for a variety of applications,
such as cell phones, PDAs, cameras.
These cells are high-quality Chinese
cells, made in an ISO certified
environment. PowerStream has qualified
this factory as being one of the
premier factories for lithium polymer
cells. Not exactly paper thin, but as
thin as we know how!
Though
these cells have small capacities they
are about the same as coin and button
cells and have a wide range of
applications. There are
microcontrollers that draw less than 1
microamp, such as the TI MSP430 in
standby mode, so a 50 mAH battery could
run these for 2 years between
charges.
Flat batteries can be
used for military, sensors, tags, and
cards. At about 2 mAH per square cm
these, and with power levels at 10 mA
per square cm.
Since these are
not thin-film batteries they are
available now, have a flexible
substrate, and can generate much higher
powers if need be. They use a
solid-electrolyte technology that
minimizes or eliminates any free
liquid. They do not have to be kept
flat. The 0.5 mm cells can be flexed or
bent into a cylinder, into a hat band,
belt, etc.

120°C for less than 20 seconds and
140°C for less than 5
seconds.
8. End-of-discharge voltage

discharging is -20 to +60°C
Ultrathin Lithium Polymer
Cells.
Note
at this time we have a few standard
products (see the table with the "add
to cart" buttons below. Most customers
at this time are using cells made to
their specifications and will require a
tooling charge and minimum order of
2000 pieces. Below are listed typical
parameters for such
cells.
We have a
small quantity of out-of-spec
PGEB0052081 and PGE0054253 cells for
electrical testing, but they are not
available for production without paying
a tooling charge.

These are great cells. They are
designed for low current discharge, but
the above curve shows what they do at
high current discharge rates, up to
10C.
Note the following features:
- At 100 mA (about 2C) you still get
90% of the rated capacity, terminating
at 3 volts
- At 200 mA (about 4C) you get 86% of
the rated capacity terminating at 2.8
volts
- The voltage stays high even at
these extreme currents
- Even at half an amp (10C) there is
enough energy for over 3300 pulses, 100
mSec each.
