Do you prefer polymer lithium battery or lithium ion battery?

Polymer battery is better.

Lithium polymer battery is lithium ion batteries updating and upgrading of 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.).

Polymer lithium battery advantages of basically has the following several aspects:

1. Single cells working voltage of 3.6V to 3.8V is much higher than nickel-metal hydride and nickel cadmium battery voltage of 1.2V.

2. Large capacity density, the volume density is 1.5 ~ 2.5 of Ni-Mh battery or nickel cadmium battery times, or even higher.

3. Small self-discharge, placed in a long time after its capacity loss is very small.

4. Long life, normal use its cycle life can reach more than 500 times.

5. No memory effect, not empty battery before charging, easy to use.

6. 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.

7. 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 cathode materials, the method of 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.

8. Light weight

Use 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, more aluminum shell battery20% lighter.

9. 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.

The internal resistance is small

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 has the ideal choice of remote control model to become the most promising alternative products of Ni-Mh batteries.

11. 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.

12. The discharge characteristics

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

13. 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.

Lithium ion battery: a secondary battery (rechargeable batteries), rely mainly on lithium ion transfer between is negative to work. Li is in the process of discharge? In the back and forth between the two electrodes embedded and embedded off; When charging, Li? Pass through falls off the anode, electrolyte embedded negative, negative in rich lithium condition; TV is on the contrary. Lithium ion battery application prospect is very broad, is currently mainly used for mobile phones and laptop computers, is the representative of modern high-performance batteries.

Polymer lithium battery: 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.
