We are offering lithium ion batterie. Innovation in li-ion batterylifepo4 power battery: faster charging and safer performance. It is clear that the small capacity li-ion (polymer) battery containing lithium cobalt oxide (licoo2) offers a genuinely viable option for electronics and digital applications. However, lithium cobalt oxide (licoo2) is very expensive and un-safe for large capacity li-ion battery. Recently lithium iron phosphate (lifepo4) has been becoming "best-choice" materials in commercial li-ion (polymer) batteries for large capacity and high power applications, such as lap-top, power tools, e-wheel chair, e-bike, e-car and e-bus. A lifepo4 battery has hybrid characters: as safe as lead-acid battery and as powerful as lithium ion cells. The advantages of large format li-ion (polymer) batteries containing lithium iron phosphate (lifepo4) are listed as below: 1. Fast charging:during charging process, a conventional li-ion battery containing lithium cobalt oxide (licoo2) needs two steps to be fully charged: step 1 is using constant current (cc) to get 60% state of charge (soc); step 2 takes place when charge voltage reaches 4.2v, upper limit of charging voltage, turning from cc to constant voltage (cv) while the charging current is taping down. The step 1 (60%soc) needs two hours and the step 2 (40%soc) needs another two hours. Lifepo4 battery can be charged by only one step of cc to reach 95%soc or be charged by cc+cv to get 100%soc. The total charging time will be two hours.

We are offering polymer lithium-ion batteries polymer lithium-ion batteries differentiate themselves from conventional lithium-ion battery systems in the types of both electrolyte and shell used. The original design, dating back to the 1970s, when french professor m. Armand proposed to use a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows ions exchange (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte. In order to obtain excellent lithium ion conductivity, some gelled electrolyte has been added into polymer lithium-ion batteries. Most of the commercial polymer lithium-ion batteries used today for mobile phones are a hybrid cells and contain gelled electrolyte. In addition, instead of using a metal can as battery shell, polymer lithium-ion batteries employ the laminated aluminum foil as battery case, which is lighter, thinner, more flexible and safer. The advantages of polymer lithium-ion batteries are listed as followings:very low profile - batteries resembling the profile of a credit card are feasible: cell thickness measuring as little as one millimeter (0.039 inches). flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically. lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell. improved safety - more resistant to overcharge; less chance for electrolyte leakage.
