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 10% 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 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.
