Advantages of lithium ion polymer batteries
Lithium Polymer battery in the structure of the use of aluminum plastic flexible packaging, different from also love cell metal shell, once the occurrence of safety risks, the liquid cell is easy to explode, and the polymer cell will only gas.
2. The thickness is small and can be made thinner
The thickness of ordinary liquid lithium-ion battery is less than 3.6mm, which is a technical bottleneck. This problem exists in the polymer cell, and the thickness can be less than 1mm, which is in line with the current demand direction of mobile phones.
3. Light weight
Polymer lithium-ion batteries are 40% lighter than steel lithium-ion batteries of the same capacity and 20% lighter than aluminum lithium-ion batteries.
4. Large capacity
Polymer lithium-ion battery steel shell battery capacity of the same size specifications 10-15%, 5-10% higher than aluminum shell battery, become the first choice of color screen mobile phone and MMS mobile phone, now on the market new color screen and color screen mobile phone also mostly use polymer cell
5. Small internal resistance
The internal resistance of the polymer batteries is less than liquid batteries, polymer batteries internal resistance even at present but do below 35 m, greatly reduced the battery power consumption, extend the standby time of mobile phone, can achieve this support level in line with international standards of large discharge current polymer li-ion battery, the ideal choice of remote control model to become the most promising alternative products of nimh batteries.
6. Customizable shape
Polymer battery can be added or reduced cell thickness according to customer demand, the development of new cell models, cheap, short die opening cycle, some can even be customized according to the shape of the mobile phone, to make full use of the battery shell space, improve the battery capacity.
7. Excellent discharge characteristics
Polymer cells use colloidal electrolytes, alternating electrolytes with a smooth discharge and a higher discharge platform than liquid electrolytes.
1. The working voltage of single battery is as high as 3.6V ~ 3.8V, which is much higher than the 1.2V voltage of NiMH and NiCd batteries.High capacity density, its capacity density is NiMH or NiCd battery 1.5~2.5 times, or higher.The self-discharge is small, and the loss of capacity is small after placing for a long time.Long life, normal use of its cycle life can reach more than 500 times.No memory effect, before charging will not have to empty the remaining electricity, easy to use.Good safety performance: polymer lithium ion battery in the structure of the aluminum plastic flexible packaging, different from the metal shell of the liquid cell, once safety risks occur, the liquid cell is easy to explode, and the polymer cell will only gas drum at most.Thickness is small and can be made even thinner: so thin that the battery can be assembled into a credit card.The ordinary liquid lithium battery adopts the method of first customizing the shell, and then plugging the anode and cathode materials. The thickness of the battery is less than 3.6mm, and there is a technical bottleneck. The polymer battery cell does not have this problem, and the thickness can be less than 1mm, which meets the current demand direction of mobile phones.
Light weight: batteries with polymer electrolytes do not need a metal case as a protective packaging.The polymer battery is 40% lighter than the steel-clad lithium-ion battery of the same capacity and 20% lighter than the aluminum-clad battery.
