Product performance:
1. Good safety performance. Built in circuit protection board, with
short circuit, overcharge,over discharge, shock, vibration,
acupuncture, high temperature,no explosion ,etc.
2. Stable performance. Long cycle life, after 500 times of
ontinuous charge and discharge,the battery capacity shall not be
less than 80% of the rated capacity.
3. Small thickness and high volume utilization. Polymer lithium
battery overcomes Lithium battery in the thickness of the
bottleneck, to achieve ultra-thin settings, and can assemble it
into a credit card. Polymer cell can achieve thickness up to less
than 1 mm, in line with the current demand for mobile phones.
4. Quality assurance. It adopts A-product cell with high capacity
and low internal resistance.
5. Shape can be customized. Polymer lithium battery models and
capacities are available,it has strong applicability.
6. No memory effect. It can be charged and discharged at any time.
Conductive Coating of Lithium Battery
A conductive coating is called pre coating, in the Lithium Battery
industry usually coated on the surface of the anode current
collector foil, a layer of conductive coating, coated with a
conductive coating of aluminum foil is called pre coated aluminum
foil or aluminum foil coating, the first experiment in the battery
can be traced back to 70s, in recent years, with the new energy
industry. Especially the lithium iron phosphate battery development
fast, which becomes the hottest new technology and new materials.
The conductive coating can effectively increase the adhesion of the
polar plate, reduce the usage of the binder and improve the
electrical performance of the battery.
Application :
Lighting, backup power supply, wind energy storage, communication
equipment, IT products, IC card terminal, GPS system, LED lights,
medical equipment,instrumentation, beauty and hair products,
electric toys, flashlight, miner's lamp, agricultural machinery
equipment, electric tools, etc.
Performance Curves of Lithium Cell:
1.Lithium Cell Charge Curve (Charge at 1C)
2. Lithium Cell Discharge Curve (Discharge at 1C )
3. Lithium Cell Cycle Life Curve
