1.No leakage: Without any liquid electrolyte, colloidal solid is used inside the polymer battery. 

2.Can be made into thin form battery: With 3.6v 400mAh, it can be thin to 0.5mm.

3. Can be design to many shapes. 

4.Can be bent and distorted: polymer battery can be bent to about 900.

5.1. Can be made into high voltage in single cell: liquid electrolyte battery increase its voltage by several cells parallel connection. Different from that, because there is no liquid inside the polymer battery, it can increase voltage by combining multi-layer in single cell.

6.1. Its capacity is twice as high as the same size lithium ion battery.
