1. Good safety performance
The structure of the polymer lithium-ion battery is an aluminum-plastic flexible package, which is different from the liquid battery with a metal shell. Once a safety hazard occurs, the liquid battery is easy to explode, while the polymer battery can only be inflated.
2. Light weight
The polymer battery is 40% lighter than the steel case lithium-ion battery of the same capacity and 20% lighter than the aluminum case battery.
3. Small thickness, can be made thinner
Ordinary liquid lithium-ion batteries use the method of customizing the casing first, and then plug in the positive and negative electrode materials. The thickness below 3.6mm has a technical bottleneck, but polymer batteries do not have this problem. The thickness can be less than 1mm, which meets the needs of current mobile phones.
4. Can be self-meaning shape
Polymer batteries can be added or reduced in thickness according to customer needs, and new battery models can be developed. The price is cheap and the mold cycle is short. Some can even be customized according to the shape of the mobile phone, making full use of the battery shell space and increasing the battery capacity.
5. Large capacity
The polymer battery is 10~15% higher than the steel case battery of the same size, and 5~10% higher than the aluminum case battery. It is the first choice for color screen mobile phones and MMS mobile phones. Most of the new color screen and MMS mobile phones on the market now also use polymer batteries.
6. The design of the guard plate is simple
Due to the use of polymer materials, the battery will not catch fire or explode, and the battery itself has sufficient safety. Therefore, when designing the protection circuit of the polymer battery, it can be considered to omit the PTC and fuse, thereby saving the cost of the battery.
7. Good discharge characteristics
Polymer batteries use colloidal electrolytes, which have stable discharge characteristics and a higher discharge plateau than liquid electrolytes.
8. Small internal resistance
The internal resistance of polymer batteries is smaller than that of liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35m, which greatly reduces battery power consumption and prolongs the standby time of mobile phones, which can reach the international level. This polymer lithium-ion battery supports large discharge current and is ideal for remote control models and is the most promising alternative to nickel metal hydride batteries.
