8 Advantages of Lithium Polymer Batteries

Lithium polymer battery is a kind of lithium-ion battery, but it has obvious advantages over liquid lithium battery (with high energy density, more compact, ultra-thin, lightweight, and high safety and size), is a novel battery. Below we detail the advantages of lithium polymer batteries.

1. Good safety performance

Lithium polymer batteries are structured in soft aluminum-plastic packaging, which is different from the metal case of liquid batteries. Once a safety hazard occurs, the liquid batteries are liable to explode, and the lithium polymer batteries can only be inflated.

2. Can be made thinner

Ordinary liquid lithium batteries adopt the method of customizing the casing first and then plugging the positive and negative electrodes. The thickness is less than 3.6mm. There is a technical limitation. The lithium-polymer battery does not have this problem. The thickness can be less than 1mm( ultra-thin battery can be 0.4mm in thickness), which meets the current mobile phone requirements.

3. Lightweight

Batteries with polymer weights do not require a metal case as protective packaging. Lithium polymer batteries are 40% lighter than steel-case lithium batteries of the same capacity and 20% lighter than aluminum-case batteries.


4. Large capacity

Polymer batteries have a capacity 10 ~ 15% higher than steel-case batteries of the same size and specifications, and 5 ~ 10% higher than aluminum-case batteries. They have become the first choice for color screen mobile phones and MMS mobile phones. The newest color screen and MMS mobile phones currently on the market also Polymer batteries.

5. Small internal resistance

The internal resistance of lithium polymer batteries is smaller than that of ordinary liquid batteries. At present, the internal resistance of domestic polymer batteries can even be less than 35mΩ, which greatly reduces the self-power consumption of the battery and extends the standby time of the mobile phone. It is completely possible. Reached the level of international standards. This kind of polymer lithium battery that supports large discharge current is an ideal choice for remote control model, and it has become the most promising product to replace the nickel-metal hydride battery.

6. The shape can be customized

Lithium polymer batteries can increase or decrease the cell thickness according to customer needs, develop new cell models, are cheap, have short mold opening cycles, and some can even be tailored to the shape of the cell phone to fully utilize the battery case space and enhance the battery capacity.

7.Good discharge characteristics

Lithium polymer batteries use colloidal electrolytes, which are subdivided into liquid electrolytes. Colloidal electrolytes have stable discharge characteristics and a higher discharge platform.


8.Simple protection plate design

Because of the use of polymer materials, the battery core does not ignite, does not explode, and the battery core itself has sufficient safety. Therefore, the protection circuit design oflithium polymer batteries can consider omitting PTC and fuses, thereby saving battery costs.
