Features
1. High Energy Density
300Wh/L~500Wh/L according to the C-rate;
2. High Voltage
Lipo cells has much higher voltage than Li/MnO2 batteries, vanges from 3.6V to 3.9v;
3.Good safety performance
With UL test itmes, there is no fire or explosion but only expansion.
4. Pollution-free
The lithium ion battery does not contain any polluting substances such as cadmium, lead, mercury, etc.
5. Non-metal Lithium
No lithium meta is adopped in a lithium ion battery, suitable for aircraft transportation;
6. Long Cycle Life
Under normal conditions, the lithium ion battery has a life of more than 500 charge/discharge cycles or more.
7. No Memory Effect
The lithium ion battery is free from the so-called memory effect, a phenomenon seen in nickel-cadmium in which the apparent battery capacity decreases when shallow charge and discharge cycles are repeated.
8. Fast Charge Capacity
The lithium ion battery can be fully charged in 1 to 2 hours, using a constant-current / constant-voltage (CC/CV) type dedicated charger with a rated voltage of 4.2V per cell.
Application
The battery have wide applications:
Portable DVDs, laptop computers, mobile phones, blue-tooth devices, MP3/MP4 players, PDA's, R/C planes, power-driven tools & toys, battery-operated bicycles/cars have already adopted LIPO-'s polymer technology.
