Compare the difference between lithium ion battery and polymer lithium battery

A lithium polymer battery refers to a lithium ion battery that is all solid or gel is too electrolyte. Generally, an aluminum-plastic composite film is used as a packaging material. There are currently only two real lithium polymer batteries in the world. One is Japan's SONY, and the other is China's ATL.

A lithium battery generally refers to an aluminum shell battery, the electrolyte is in a liquid state, and the outer packaging material is an aluminum shell.

Lithium polymer batteries are safer than lithium batteries. Lithium polymer batteries are upgraded products of lithium ion batteries. Compared with the current popular lithium-ion battery, it has the advantages of large capacity, small size (thin), and safety (no explosion). However, due to the time required for the replacement of the entire industry chain, its cost (cost) is still relatively high, and it is only used in high-end digital products (ultra-thin notebook computers, etc.).

It is foreseeable that in the next 5-10 years, lithium polymer batteries will replace the existing lithium-ion batteries! In fact, the popularity of lithium polymer batteries in countries such as Japan and South Korea, which are more developed in the electronics industry, has reached a certain level, but China is still relatively backward in this respect. Let us wait and see! In the near future, mobile phones with lithium polymer batteries will be cheaper. I must replace this more secure mobile phone (battery)!

Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has a variety of obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety and low cost battery. In terms of shape, the lithium polymer battery has an ultra-thinning feature and can be fabricated into a battery of any shape and capacity in accordance with the needs of various products. The battery can reach a minimum thickness of 0.5mm. Compared to lithium ion batteries, lithium polymer batteries have the following characteristics:

1. There is no battery leakage problem. The battery contains no liquid electrolyte and uses colloidal solid.

2. Can be made into a thin battery: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm.

3. The battery can be designed in a variety of shapes.

4. The battery can be bent and deformed: the polymer battery can be bent up to about 90°.

5. A single high-voltage: liquid electrolyte battery can only be connected in series with several batteries to obtain a high voltage, and the polymer battery can be made into a multi-layer combination in a single piece to achieve a high voltage because it has no liquid.

6. The capacity will be twice as high as the same size lithium-ion battery.
