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.
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. Light weight. Polymer lithium battery does not need to use metal
shell as outer packaging.In quality, it is 40% lighter than that of
steel shell lithium battery with the same capacity shell batteries
are 20% lighter.
5. Quality assurance. It adopts A-product cell with high capacity
and low internal resistance.
6. Shape can be customized. Polymer lithium battery models and
capacities are available,it has strong applicability.
7. No memory effect. It can be charged and discharged at any time.
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
What is the Cycle Life of Lithium-Ion Batteries?
There are many factors that endanger the service life of the
lithium battery's circulatory system, but the direct reason is that
the total number of lithium-ion batteries participating in kinetic
energy transmission continues to decrease. It must be emphasized
that the total output of lithium in rechargeable batteries has not
decreased, but the active lithium-ion batteries are becoming less
and less. They are restricted elsewhere or in the safe passage of
themed activities, and cannot participate in the circulatory system
battery charge and discharge at will. The whole process.
Under normal conditions, lithium batteries have been operating for
2 to 4 years, and the recharging frequency of the recycle battery
is about 300 times. According to the quality of the rechargeable
battery and the materials of the lithium battery, the life
frequency of the lithium battery is clarified:
1. The frequency of the circulation system of ternary materials is
around 800.
2. The cycle frequency of lithium iron phosphate battery is about
2500 times.
3. The frequency of the genuine lithium battery cycle system is
different from that of the defective lithium battery cycle system.
The genuine rechargeable battery is designed, manufactured and
manufactured according to the cycle system frequency on the
manufacturer's instructions. The frequency of the defective battery
cycle system is sometimes very high. It may not be easy to
circulate the system 50 times.
The current life of the 18650 cycle system can be up to 500 to 1000
times, and if it is a rechargeable battery produced by a reliable
manufacturer, the life of the 18650 cycle system can be up to 2000
times. Of course, if it is a defective product Or counterfeit
rechargeable batteries, then it is too short.
Its service life is divided into cycle time service life and
schedule service life. Cycle time service life refers to the
frequency of the battery charging cycle time of a rechargeable
battery; calendar table service life refers to the time from
production to completion of the rechargeable battery. The service
life of this type of cyclic system refers to the frequency of
recharging the battery of the lithium battery recyclable system.
