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.
Features:
1. High operating voltage(3.6V)
2. Energy
density is high,
3. No memory effect
4. Self-discharge is less than 3% per month
5. Charge/discharge cycle characteristics are excellent
6. Safety characteristics are
excellent
7. Processing temperatures for these cells is 100°C for less than 60
seconds, 120°C for less than 20 seconds and 140°C for less than 5 seconds.
8.
End-of-discharge voltage cut off 2.8 volts.
9. Temperature range of charging is 0-45°C,
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.
