1). Advantages of Lithium-ion polymer battery (8 points)£º

1. Security capability: Lithium-ion polymer battery adopts Aluminum-plastic package in the structure, it is unlike the liquid batteries with metal shell, in case of a potential safety problems, liquid batteries will be explosible easily, but polymer batteries will just gas drum.

2. Small thickness and more thinner: Ordinary liquid lithium-ion battery used to customize frames, and then the anode and cathode material are foisted into the metal shell, but less than  3.6 mm thickness is their technical bottleneck, this issue does not exist in the Lithium-ion polymer batteries, Less than 1mm thickness can be achieved to accord with the current demand trend for mobile phone.

3. Light weight : The weight of Polymer battery is same about 60% with Lithium-ion battery in steel shell and about 80% of Aluminums-shell battery.

4. Large capacity. The capacity of Polymer battery that same size and specifications are more higher 10 ~ 15% than the capacity of the battery with steel shell and higher 5 ~ 10% than Aluminums-shell battery. The polymer batteries have been used as the premier choice of the new color screen mobile phones.

5. Small resistance. The resistances of polymer batteries are smaller than the ordinary liquid batteries. The resistance of the polymer batteries in domestic can even be below 35m¦¸, and greatly reduce the power consumption of batteries, meanwhile it can extend the standby time and is entirely possible to reach the world's level. The support with the discharge current of Lithium-ion polymer battery is the ideal choice for remote control model and become the most promising products to substitute Ni-Hydrogen battery.

6. Forms can be customized: Polymer battery can increase or decrease the thickness of batteries under the customer's needs, to develop new models with lower prices, a short-cycle module, or even the phone can be shaped tailored to take fully advantage of battery shell space and upgrade the battery capacity.

7. Good discharge: Polymer battery adopt colloidal electrolyte, so it has a smooth discharge characteristics and higher discharge platform, which compared with liquid electrolyte

8. The simple design protection board: because of using polymer materials, polymer batteries will not fire and explode, the batteries itself with adequate security, therefore polymer battery protection circuit design may make you consider to omit PTC and fuses and save the cost of batteries.

2) Distinction betweenLithium-ion polymer battery and liquid lithium- ion battery:

Their most fundamental difference is using the two different electrolyte .The electrolyte of Lithium polymer battery was called solid polymer electrolyte because of its solid state from the exterior view,. This electrolyte is a kind of solid state, but it can support electrolyte like liquid's dissolution and occur the phenomenon of ion migration..

3)  Development trend and prospect of Lithium-ion polymer battery:

Lithium-ion polymer battery technology is mature in global and its commercialization has been for more than three years, although the sales is in the fast-growing, but its market share was below 10%, and cooperation with the market share 90% of liquid lithium, its far below the people's expectations. For various reasons, the prices of polymer battery in the current market generally are higher than the liquid lithium battery, but the mode of competition in the mobile electrical is quietly changing, in particular polymer battery mobile appliances bring the value of innovative design (the advantage of below 4mm thickness and large specifications),It is being known by more designers of mobile phone, mobile DVD, so the manufacturers of the polymer battery are confident or convinced that the era of polymer will come.

As per the development of mobile phone, it has the following trends:

(1). Miniaturization and super-thin characters of mobile phone facilitate consumers to carry;

(2). Personalized design concept make the shape of mobile phone the ¡°original¡± no longer, the design modeling of irregular shape, curve, globoid have been becoming the mainstream of mobile phone aesthetics design.

(3) The use of color screen phone has been increasing.

To enable the miniaturization of mobile phones, batteries has been decreased, more thinner is a most effective way. Thin cell phones of the 4mm thickness have become the mainstream trends, the configuration, effective cost are the polymer's expertise. Irregular shapes, curves, design modeling globoid cell phone to stay the effective space into irregular shapes. Liquid square space can't be effective use and lower capacity, but laminated and anomalies polymer can be the most effective use and also can enlarge the capacity. TCL Corporation recently introduced the arc-shaped battery, trapezoidal batteries, backpack battery to the market, they can increase the capacity of 50% than the corresponding specifications of liquid battery. More phone functions is resulting in more and more power demand. Request a corresponding increase in battery capacity. No increase in the thickness of the battery, battery polymerization has the obvious advantages.
With the similarity, notebook PC, Bluetooth headsets, handsets, mobile DVD etc electric devices, their direction of the development is being portable, and equipped with a liquid crystal display, with their features on the rise and growing in the LCD screen. All this polymer lithium-ion battery will be provided a unlimited business opportunities.
