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

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 100 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.
