1. Good safety performance

　　The polymer lithium battery uses aluminum-plastic flexible packaging in the structure, which is different from the metal shell of the liquid battery. Once there is a security risk, the liquid battery is prone to explosion, and the polymer battery will only bulge at most.

　　2. Small thickness, can be made thinner

　　Ordinary liquid lithium battery uses the first custom shell, and then plug the positive and negative electrode village material method, the thickness is less than 3.6mm, there is a technical bottleneck, the polymer cell does not exist this problem, the thickness can be less than 1mm, in line with the current mobile phone demand direction.

　　3. Light weight

　　The weight of the polymer battery is 40% lighter than the steel shell lithium battery of the same capacity specification, and 20% lighter than the aluminum shell battery.

　　4. Large capacity

　　Polymer batteries are 10 ~ 15% higher than the steel shell battery of the same size, 5 ~ 10% higher than the aluminum shell battery, becoming the first choice for color screen mobile phones and MMS mobile phones, and most of the new color screens and MMS mobile phones on the market now use polymer batteries.

　　5. Low internal resistance

　　The internal resistance of the polymer cell is smaller than that of the general liquid cell, and the internal resistance of the domestic polymer cell can even be below 35mΩ, which greatly reduces the power consumption of the battery and extends the standby time of the mobile phone, and can fully reach the level of international standards. This polymer lithium battery, which supports large discharge currents, is an ideal choice for remote control models and has become the most promising alternative to Ni-MH batteries.
