What's the difference between polymer lithium batteries and lithium batteries?

Lithium ion batteries and lithium polymer battery have their respective advantages and disadvantages.

Polymer lithium battery with the advantages and disadvantages of lithium ion battery can't think.

A, advantages:

1. Good safety performance

Lithium-ion polymer battery with aluminum composite flexible packaging in the structure, different from liquid metal case of batteries, in the event of a safety hazard, liquid batteries easy explosion, gas drum and polymer batteries will only at most.

2. The thickness is small, can do more thin

Ultra-thin, batteries could assemble into a credit card.Ordinary liquid lithium electricity use custom shell, after the plug is the method of the cathode, thickness of 3.6 mm the following technical bottlenecks, polymer batteries, there is no this problem, the thickness can be below 1 mm, can meet the demand of current mobile direction.

3. Light weight

Using polymer electrolyte battery without metal shell as a protective outer packing.Polymer battery weight is the same volume of steel shell lithium electricity 40% lighter, moreAluminum shell battery20% lighter.

4. Large capacity

Polymer battery is the same size of the steel shell battery capacity, 10 to 15% more than high aluminum battery 5 ~ 10%, be the first choice of the color screen mobile phones and MMS, now on the market a new color and MMS phones are mostly used polymer batteries.

5. Small internal resistance

The internal resistance of the polymer batteries is less than liquid batteries, the current domestic internal resistance of the polymer batteries can even do below 35 m Ω, greatly reduced the battery power consumption, extend the standby time of mobile phone, can reach with international level.The support of large discharge current polymer li-ion battery, the ideal choice of remote control model to become the most promising alternative products of nimh batteries.

6. The shape can be customized

Manufacturers need not limited to the standard shape, able to make the appropriate economic size.Polymer battery can increase or decrease the thickness of the batteries according to the customer's demand, the development of new batteries models, price cheap, open mold cycle is short, some even can be tailored according to the mobile phone shape, to make full use of the battery shell space, improve battery capacity.

7. Discharge characteristics

Polymer battery using gel electrolyte, compared to liquid electrolyte, colloid electrolyte with smooth discharge characteristics and higher discharge platform.

8. Simple protection board design

Because of using polymer materials, batteries, no fire, no explosion, batteries itself has enough safety, therefore, polymer battery protection circuit design can consider omitting PTC and fuse, thereby saving the cost of battery.

Second, the disadvantages:

1, compared with lithium ion battery energy density, and cycles are falling.

2, the manufacture is expensive.

3, there is no standard shape, most battery manufacturing for high volume consumer market.

4, compared with those of lithium ion batteries, higher energy prices

According to the electrolyte materials that are used in lithium ion batteries, lithium ion batteries are divided into liquid lithium ion battery (Liquified Lithium - Ion Battery, LIB for short) and Polymer lithium ion batteries(Polymer Lithium - Ion Battery, for PLB) or plastic lithium ion battery (Plastic lithium ion batteries, for PLB).Is used in the polymer lithium ion battery cathode materials and liquid lithium ion is the same, the anode materials are divided into cobalt acid lithium, manganese acid lithium, ternary material and lithium iron phosphate material, negative extremely graphite, working principle of the battery is almost the same.Their main difference is that the different electrolytes, liquid lithium ion battery using liquid electrolyte, polymer lithium ion battery with solid polymer electrolyte as a substitute for, the polymer can be "dry", also can be "colloidal", at present most of the polymer gel electrolyte.

Do you mean the full name of polymer battery is lithium polymer batteries.It is a kind of lithium-ion batteries.Say from batteries, lithium batteries, lithium batteries can be divided into the first generation of steel shell of the second generation aluminum shell lithium-ion batteries, the third generation of polymer lithium battery.Due to polymer battery is encapsulated with aluminum composite membrane, membrane thickness of only 0.3 m, can carry reaction material internal space, the largest aluminum composite membrane many lighter than the steel shell aluminum shell, aluminum composite membrane of korah, effectively slow down the battery adverse reactions to pressure, to avoid the possibility of an explosion.Polymer lithium battery is the highest capacity lithium battery, the light in weight, safety, the best batteries.

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 and upgrading, its cost (cost) is still relatively high, 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.
