Which is better, polymer lithium battery or lithium battery？

Customers often ask about the difference between lithium-ion batteries そして lithium-polymer batteries, and which battery is more recommended.

Lithium polymer batteries refer to all-solid-state or gel-to-electrolyte lithium-ion batteries. Aluminum-plastic composite films are generally used as packaging materials.

Lithium battery generally refers to aluminum shell battery, the electrolyte is liquid, and the outer packaging material is aluminum shell.

Lithium polymer batteries are safer than lithium batteries. Lithium polymer battery is an upgraded product of lithium ion battery. Compared with the popular lithium-ion battery, it has the advantages of large capacity, small size (thin), and safety (no explosion). However, because the replacement of the entire industry chain takes a certain amount of time, its cost (cost) is still relatively high.

Polymer electrolytes not only have good electrical conductivity, but also have the characteristics of light weight, good elasticity, and easy film formation that are unique to polymer materials.

It is foreseeable that in the next 5-10 years, lithium polymer batteries will definitely replace the existing lithium ion batteries!

Lithium polymer battery (Li-polymer, also known as polymer lithium battery): It has many obvious advantages such as high energy density, smaller size, ultra-thinness, light weight, high safety and low cost. It is a new type of battery. Battery. In terms of shape, lithium polymer batteries have ultra-thin characteristics, and can be made into batteries of any shape and capacity to meet the needs of various products. The minimum thickness that this type of battery can achieve is up to 0.5mm. Compared with lithium-ion batteries, the characteristics of lithium polymer batteries are as follows:

1. There is no battery leakage problem, the バッテリー does not contain liquid electrolyte, and uses colloidal solids.

2. It can be made into a thin バッテリー: with a capacity of 3.6V400mAh, its thickness can be as thin as 0.5mm.

3. The battery can be designed in various shapes.

4. The バッテリー can be bent and deformed: the polymer battery can be bent at a maximum of about 90°.

5. It can be made into a single high voltage: the バッテリー with liquid electrolyte can only obtain high voltage by connecting several batteries in series, while the polymer battery can be made into a multi-layer combination in a single cell to achieve high voltage because it has no liquid itself.

6. The capacity will be double that of the same size lithium-ion battery.
