Advantages of polymer batteries

1.Small thickness, can be made thinner

Ultra-thin, with batteries that fit into credit cards. Common liquid hammer adopts the method of customizing the shell first, and then plugging the positive and negative electrode materials. The technical bottleneck exists when the thickness is less than 3.6mm, while the polymer core does not have this problem. The thickness can be less than 1mm, which is in line with the current demand direction of mobile phones.

2.Light weight

Batteries with polymer electrolytes do not need metal shells as protective outer packaging. The weight of the polymer battery is 40% lighter than the steel shell carp battery of the same capacity specifications, and 20% lighter than the aluminum shell battery

3.Large capacity

Polymer battery capacity is 10 ~ 15% higher than the steel shell battery of the same size. 5 ~ 10% higher than aluminum shell battery, become the first choice of color screen mobile phone and MMS mobile phone. Now the market out of the new color screen and MMS mobile phone also mostly use polymer cell

4.Low internal resistance
The internal resistance of the polymer cell is smaller than that of the general liquid cell. At present, the internal resistance of the domestic polymer cell can even be below 35mΩ. Which greatly reduces the self-charging power of the battery and extends the standby time of the mobile phone.

It can fully reach the level of international standards. This kind of polymer physical electricity which supports large discharge current is the ideal choice of remote control model. And becomes the most promising alternative to nickel metal hydride batteries.

5.The shape can be customized
Manufacturers are not limite to the standard shape and can economically fit it to the right size. The polymer battery can increase or decrease the thickness of the cell according to customers’ needs, and new cell models can be develope. The price is cheap and the mold opening cycle is short. Some can even be customize according to the shape of the mobile phone, so as to make full use of the battery shell space and improve the battery capacity.

6. Good discharge characteristics
Polymer batteries use colloidal electrolytes, which have smooth discharge characteristics and a higher discharge platform than liquid electrolytes.

7. The protection plate design is simple
Due to the use of polymer material, the cell does not fire, does not explode. The cell itself has enough security, so the protection circuit design of polymer battery can be considere to omit PTC and fuse, so as to save the battery cost
