Lithium polymer battery: it is also a kind of lithium-ion battery, but compared with liquid lithium battery, it has many obvious advantages, such as high energy density, miniaturization, ultra-thin, lightweight, high security and so on. It is a new type of battery. The design capacity of a single lithium-ion polymer battery is 50mah-15000mah, and thickness ranges is 1mm - 20mm, mainly including cylindrical, square and button batteries. According to UL, CE and other safety certification standards, we have done experiments of collision, overcharge, short circuit, nailing and burning, and even under some improper use conditions, the batteries can be used safely.

Main performance of GreenTech Electronic’s polymer lithium battery:

1. Long service life: under normal use conditions, the battery cycle is more than 500 times.

2. High rate charging and discharging performance: under specified conditions the battery can be fully charged in one hour and discharge above 10C current.

3 Wide temperature range: in high and low temperature environment, the battery performance is stable, and the working temperature range is - 10 ℃ - 70 ℃.

4. Good storage performance: at room temperature (20 ± 5 ℃), the capacity of the battery remains above 70% after 1 month storage.

5. High stability: GreenTech Electronic adopts the best materials, advanced production process and technology to make our battery performance stable and reliable.

Main application applications polymer lithium battery:

1. Communication equipment: mobile phone, PHS phone, Bluetooth phone, interphone;

2. Information equipment: laptop, PDA, portable fax machine, printer;

3. Audio and video equipment: digital camera, camera, portable DVD, VCD;

4. Others: electric bicycle, miner lamp.
