Which one is better for cell phone, lithium battery or polymer battery?

Lithium polymer battery is lithium ion battery upgrading products. As for the lithium ion battery in fashion now, it has a large capacity, small size (thin), security (no explosion), etc. However, because of the whole industry chain and upgrading, its cost still relatively high, and is only used in high-end digital products (ultrathin laptop computers, etc.).

Predictably, in the next 5-10 years, lithium polymer battery will replace the existing lithium-ion batteries! In fact, in the electronics industry more developed countries such as Japan and South Korea the popularity rate of lithium polymer battery has reached a certain level, only in this respect is relatively backward in our country, let us wait and see!, etc. in the near future with lithium polymer battery cell phone cheaper, I have to change a new cell phone this safer (battery)!

Lithium polymer battery (Li - polymer, also known as the polymer lithium battery) : with high energy density, miniaturization, ultra-thin, lightweight, and high safety and low cost, and other obvious advantages, is a new type of battery. In shape, lithium polymer battery with ultra-thin characteristics, can match the needs of the various products, made into any shape and the capacity of the battery. The battery can achieve the minimum thickness of 0.5 mm. The relative to the lithium ion battery, lithium polymer battery characteristics are as follows:

1. No battery leakage problems, its inside the battery does not contain liquid electrolyte, the use of colloidal solids.

2. Can be made into thin battery: 3.6 V400mAh capacity, its thickness can be thin to 0.5 mm.

3. The battery can be designed into various shapes.

4. The battery can be bending deformation: polymer battery maximum bending around 90 °.

5. Can be made into a single high voltage: liquid electrolyte battery only with the number of cells in series with high voltage, and the polymer batteries as there is no liquid itself, can be made within the single star multilayer combination to achieve high voltage.

6. Capacity will is more than double that of the same size of lithium ion batteries.

Lithium polymer battery refers to all solid state or gel too for electrolyte of lithium ion battery. Generally USES aluminum-plastic composite membrane as a packaging material. Only two in the world is really the lithium polymer battery. One is Japan's SONY, one is the ATL in China

Generally refers to the aluminum shell batteries, lithium-ion batteries for liquid electrolyte for aluminum shell, packaging materials,

Lithium polymer battery is safe than lithium battery. Lithium polymer battery is lithium ion battery upgrading products. Relative to the lithium ion battery in fashion now, it has a large capacity, small in size (thin), security (not bang), etc. However, because of the whole industry chain of generation, its cost (cost) is still relatively high, only used in high-end digital products (ultrathin laptop computers, etc.).

Lithium-ion battery has production of lithium ion battery (LiB) and a liquid polymer lithium ion batteries(LiP) two kinds. So in many cases, the battery on the Li - ion, must be a lithium-ion battery. But is not necessarily a liquid lithium ion battery, it is possible that the polymer lithium ion batteries. Lithium ion battery is the improved product of lithium-ion batteries. Lithium electricity...4610

Polymer battery and lithium battery, in general, polymer battery in the lithium battery security is quite high. Polymer lithium battery principle and the principle of ordinary lithium battery are just different electrolyte and the shell material. So the lithium battery is a major categories, polymer is a kind of lithium-ion batteries.

The classification of lithium battery is as follows:

1. According to the battery cathode material

A.    lithium iron phosphate batteries (iron)

B. cobalt acid lithium batteries (cobalt battery)

C. nickel cobalt manganese acid lithium ternary material (battery) three yuan

D. Lithium titanate battery titanium (battery)

E. vanadium phosphate lithium battery (vanadium battery)

F. other lithium metal oxide...

2. According to the shape of the battery

A. the square cell (conventional battery)

B. cylindrical battery (18650).

C. other special-shaped battery...

3. Press the battery shell material classification

A. steel battery shell

B. aluminum battery

C. polymer battery

In addition, the classification of the battery can also according to the morphology of the electrolyte is divided into liquid, and solid state electrolyte battery. The assembly way, according to the battery pole piece can be divided into winding type battery and disc type batteries, etc. According to the battery USES, can be divided into mobile phone batteries, bluetooth battery, power battery, storage battery and so on.

About polymer battery: Domestic most do are soft package of batteries, aluminum-plastic film is shell material used for packaging, real polymer battery, in addition to the shell, use or polymer electrolyte.

Polymer battery relative to other types of lithium batteries, has the following advantages:

A. High safety. Shell using aluminum film packaging, in battery internal short circuit failure cases of extreme, will only surface bulging, not like steel battery shell/aluminum shell is in danger of explosion. Because aluminum composite membrane is more soft, more easy to deformation, won't make the gas inside the infinite accumulation, so won't explode.

B. polymer battery is easy to make all kinds of shape, and can be done very thin, and in extreme cases, the battery can be made 1 mm thick. Thanks to polymer battery aluminum-plastic film can be simply by stamping, make a desired shape, in addition, the polymer encapsulation mode using heat sealing, for laser welding of steel battery shell/aluminum shell encapsulation way, has a unique advantage.

C. aluminum composite membrane puncture strength is not enough, easy to form the Angle of a damaged, aluminum-plastic film corrosion, leakage, as well as the bad appearance.

D. the same because of the strength of the aluminum composite membrane is not enough, make the battery in the process of production, easy to cause the battery arc deformation, causing four Angle is not in a plane of the battery. This can be achieved by adding a high temperature jig baking process.

For polymer battery shell is a little softer, but also disadvantages, such as the application in the field of power battery, need battery shell have a certain mechanical strength, but used in the field of mobile phones, it is clear that some advantage more. As for capacity, cycle, energy density, such as performance, basically see the technical level of the company, after all, polymer battery just encapsulation materials is different.

All in all, the polymer battery has good security in the lithium battery, but it is prone to leakage, aluminum-plastic film corrosion etc. In aggregate, I tend to think polymer battery is better.
