Polymer Lithium ion batteries are developed based on liquid lithium ion battery, anode using LiCoO2, LiFePO4, LiMn2O4, while cathode using carbon, using polymer electrolyte foil, packing with aluminum plastic foil.
Polymer Lithium ion batteries (liPo batteries) are the new generation lithium battery. Lithium ion polymer battery not only gives high voltage, long recharge life, and steady discharge rate as liquid lithium ion battery and pollution free, but also eliminates safety hazards which liquid lithium ion battery exists. In addition, the battery design becomes more flexible, convenient, light and handy. The performance has reached or exceeded the technology parameter of liquid lithium ion battery with a better reliability.
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 GMB's polymer technology.
Main applications are;
Communications equipment: mobile phone, PHS phone, Bluetooth cell phones, walkie-talkie
Information equipment: laptop computers, PDA, portable fax machines, printers
Audio-visual equipment: digital cameras, camcorders, portable DVD, VCD
Others: electric bicycles, miner's lamp
l 能量密度高， 容量高出同行业10%~30%;

l To guarantee the long terms stability, Both anode and cathode blades are specially made for higher tenacity, and bent at 5 levels in different temperature.
Lithium Polymer Battery Work-Flow
●Mix solvent and bond separately with positive and negative active materials. Make into positive and negative pasty materials after stirring at high speed till uniformity.
● Press the above positive and negative sheets till they become flat.
5. Pole pieces
7. Insulation Test 1
●After separate anode and cathode by separator paper; a battery cell has formed, then test its insulation.
8. Sealing 1
10. Insulation Test 2
●Test insulation of the terminal of the battery and the aluminum foil.
11. Insulation Test 3
12. Vacuum Drying
13. Electrolyte filling
●Charge and discharge the battery for the first time or more times, connect it to computer, monitor and record its performance indicators.
17. Air exhausting
●Air will exit inside battery after charging, draw it away until vacuum.
18. Sealing 4
●Sort batteries according to their capacity with high-precision sorting equipments, which is watched and recorded their performances by computers at all times.
21. Aging testing
●Store batteries in batches in warehouse after inspecting their internal resistance, voltage, capacity and size in the conditions of 10~45℃ and relative humidity of 65±20%. 30 days is needed. Batteries will be re-inspected regularly every 8 days.
23. Final inspection
●Packaging consists of inner plastic tray and outer double corrugated carton, make them a whole pallet, strap them, wrap with stretch film to insure transportation safety, the packaging comply the regulation of packing storage graphic symbol GB191-1990.
