Lithium Polymer Batteries have become common in single-cell consumer applications like cell phones, blue tooth devices and GPS trackers, but industrial and commercial applications are now putting them to good use as well. The thin and custom shaped cells are now used in large, complex battery packs.
Lithium polymer cells are available in custom footprint size. They can be very thin or quite large depending on their intended use. They are becoming more and more popular for the wearable devices such as smart watches, and predicted to become quite common with annual usage over 1 billion cells by the end of coming decade.
Lithium polymer cells’ defining feature is a flexible, foil-type (polymer laminate) exterior. They still contain organic solvent. There are a wide array of different technologies used to produce these batteries - some have liquid electrolytes, some are gelled by inclusion of polymers in the electrolyte, some have the layers laminated together and others may be have their electrodes stacked rather than wound. The chemistry is the same as Li-ion. Basically, it is a Li-ion battery in a soft pack.
Key Features:
1) High operating voltage of 3.7V per cell, which is equal to either three Ni-CD or three Ni-MH cells connected in series.
2) High energy density of 100~130Wh/KG, 270~360Wh/L.
3) High discharge rate for most high power applications.
4) Stable discharge under various environmental temperature conditions.
Lithium-ion polymer batteries provide stable discharge within a wide range of temperatures from -20℃ to +60℃.
5) Superior storage characteristics
The self-discharge rate of Lithium-ion polymer battery is about 5% per month when stored at room temperature.
6) Excellent cost performance and long cycle life
Superior recharging properties ensure a service life of more than 300 cycles under normal usage conditions.
7) Environmentally friendly.
The cell does not contain any polluting substances such as Cadmium, Lead, Mercury, etc.
