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 2.0 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.

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.
