We know from the lithium ion battery gel, around it since the advent of research and development work has been constantly, in the late 1990s and develop the lithium battery, 2002 polymer gel is launched phosphoric acid lithium iron power gel battery.

Lithium ion battery consists mainly of positive gel internal anode, electrolyte and diaphragm and composed. Positive and negative and electrolyte materials and different craft differences make gel battery has different properties, and a different name. Currently on the market lithium ion battery anode materials mainly gel lithium cobalt oxide (LiCoO2), plus a few using lithium manganese oxide (LiMn2O4) and lithium nickel oxide anode materials (LiNiO2) of lithium ion batteries, general gel after two anode materials to the lithium ion battery gel is called “lithium manganese gel battery” and “lithium nickel gel battery”. The new development of lithium iron batteries phosphoric acid with dynamic gel is lithium iron (LiFePO4 materials gel battery anode) of lithium ion battery, it is gel lithium ion battery new members of the family of gel.

General lithium ion battery electrolytes are liquid gel, and later developed solid and gel polymer electrolyte, says the lithium ion battery for lithium gel polymer gel battery, its performance is better than liquid electrolyte of lithium ion battery gel.

Phosphoric acid lithium iron gel battery name should be phosphoric acid lithium iron lithium ion battery, the name gel is too long, referred to as lithium iron phosphate gel battery. Because of its performance is especially suitable for power applications, add in the name of “power” two characters, namely phosphoric acid lithium iron battery power gel. Some called it “the lithium iron (act) dynamic gel battery”.

Using the positive significance of LiFePO4 materials

Currently used for lithium ion battery anode materials mainly gel is LiCoO2: LiMn2O4, LiNiO2, and LiFePO4. These component gel battery anode materials, metal elements, cobalt (Co) is the most expensive, and storage, Ni (Ni), manganese (Mn) cheaper, and determine if flexion-extension (Fe) radiographs iron is the cheapest. Approximately 400mah price and the market price of metal. Therefore, it is made of LiFePO4 approximately 400mah lithium ion battery should be gel is the cheapest. It is another feature of environmental pollution.

As the rechargeable battery gel requirements are: high voltage, capacity, good performance, the output voltage recharge cycles stability, macrocurrent charge-discharge, electrochemical stability, safety (not in use for charging and discharging and caused by improper operation circuit burning or explosion), working temperature range wide, avirulent or less toxic and environmental pollution. For positive LiFePO4 using phosphoric acid lithium iron gel battery in the performance requirements are good, especially in large discharge rate discharge (5 ~ 10C discharge), discharging voltage stationary, safety (not burning, explosion, life cycle times), (for environmental pollution, it is the best, is by far the best large current output power gel battery.

LiFePO4 gel structure and working principle of the battery

The internal structure of LiFePO4 gel battery is shown in figure 1. On the left is peridot structure of LiFePO4 as gel battery anode, aluminum foil and gel battery by the positive connections, is among the diaphragm, polymer its positive and negative space, but the lithium ion Li + through and electronic e – not by right is composed by carbon (graphite) by the gel battery cathode, aluminum and gel battery anode connections. Gel battery between the fluctuation is gel battery electrolytes, gel battery by the metal shell airtight package.
In LiFePO4 gel battery charging, positive of lithium ion Li + through to the negative transfer of polymer diaphragm, In the process of discharging lithium ion Li, negative to the positive transfer + through the diaphragm. Lithium ion battery is for lithium ion aerogel charge-discharge back on when the migration named.

Phosphoric acid lithium iron gel battery features

Through the introduction, the battery can be induced LiFePO4 gel.

1 efficient output: standard discharge for 2 ~ 5 cs, continuous high discharge current 10C can instantly pulse discharge (10S) of public,

2 high performance: the external temperature 65 ° internal temperature is as high as 95 degrees, gel battery discharge end temperature reaches 160 degrees Celsius, gel battery structure security, intact,

3 if gel battery internal or external damage, gel battery don’t burn, explosion, safety is best,

4 excellent cycle life cycles, 500, the discharge capacity is more than 95%,

5 after discharge to zero volt and no damage,

6 but fast charging,

7 low cost,

8 for environmental pollution.

Although now of lithium iron batteries for low yield gel, still have a wide range of USES, but in the mobile phone of 3G mobile phone because of weight, volume and power supply ability to put forward higher request, that now of lithium battery has not gel can satisfy the 3G mobile phone use, at the same time, the biggest problem is gel battery will burn, would be the biggest problem. In the lithium battery family only gel lithium iron gel battery is the most appropriate.

So security is the most important, I think the price is high, I think in the temporary own life safety, the user will choose safer gel battery. So the development of 3G should priority in use of lithium iron batteries gel instead of lithium battery ordinary gel.

The company will make his mobile phone safer td-scdma, for the user, please consider using lithium iron gel battery.
