lithium iron phosphate as cathode (LIFEPO4 technology)
Due to the shortage of fossil fuels and environmental concerns, we re convinced that the green energy industry and related industries will become the main stream in the coming 30-50 years. This causes a strong demand of rechargeable batteries. However, the existing lithium ion cell systems including lithium cobalt oxide and lithium manganese oxide still suffer from low discharge rate, safety concern and short cycle life.
To solve those issues, Dr. John Goodenough and his team at University of Texas patented as potential cathode material LiFePO4 as a potential cathode in 1996. It is a very stable material due to the covalent P-O bonding which stabilize the fully charged cathode versus O2 release. scientists have developed the LiFePO4 battery using lithium iron phosphate as cathode to answer concerns in the battery for Electric Vehicles and other battery useages..
When phosphate batteries are overcharged under 3A 5V, temperature of the battery could not surpass 55°C, the battery is extremely safe; Heats up after 7-8 hour to 300°C in hot box process, battery temperature nearly the same with temperature of hot box, the battery cannot appear hotly out of control; after extrusion or acupuncture, the battery temperature cannot surpass 110°C.
The safety of lithium battery is guaranteed by using LiFePO4 as anode pole. LiFePO4 is one kind of phosphate gathering the anion, the P-O chemical bond is extremely strong, material is thermodynamically stable, do not worry about it can release the oxygen, simultaneously LiFePO4's olivine crystal structure decides its crystal lattice deformation smaller in the sufficient electric discharge process, its material structure is stable and safe, and also its cycle life are extremely long. These characteristics also can make LiFePO4 withstand oxidation and acidic environment, the battery has more electrolyte choice, the battery performance can be optimized.
Safety of LiFePO4
The safety characteristics inherent to LiFePo4 technology result from the incorporation of phosphates as the cathode material. Phosphates are extremely stable in overcharge or short circuit conditions and have the ability to withstand high temperatures without decomposing. When abuse does occur, phosphates are not prone to thermal runaway and will not burn. As a result, LiFePo4 technology possesses safety characteristics that are fundamentally superior to those of Lithium-ion batteries made with other cathode materials.
LiFePo4 technology does not contain any heavy metals and does not exhibit the "memory effect" of Nickel-Cadmium and Nickel-metal Hydride solutions. LiFePo4 technology demonstrates excellent shelf life, long cycle life and is maintenance free.
Another key benefit of our LiFePo4 technology is its flexibility, both in terms of battery application and cell design. It can be used in wound cylindrical, wound prismatic and polymer battery construction types and manufactured to fit smaller applications.
The advantages of traditional Lithium-ion coupled with the safety features of phosphates, make LiFePo4 technology the Lithium-ion technology for the future. Our LiFePo4 Lithium-ion technology utilizes natural, phosphate-based material and offers the greatest combination of performance, safety, cost, reliability and environmental characteristics.
We all use and take for granted the benefits of lithium-ion energy storage systems in our cell phones, notebooks, PDA's, consumer appliances and other devices. However, recent recalls by the US Consumer Protection Commission have brought to light the potential hazards of lithium-ion batteries. Just imagine what could happen to a large lithium-ion battery if an electric/hybrid electric vehicle were rear-ended or if a manufacturing defect or other abuse caused a thermal event in a mission critical telecom backup system. The results could be devastating.
Liberty is intent on working on developing and making available to all EV applications the LiFePo4 technology---the only safe large format lithium-ion rechargeable battery technology. We sincerely hope to have chance to cooperate with our customers all over the world and contribute the latest world-wide technology to our customers prosperous business future.

We can custom design your LiFePO4 battery to fit your needs.
Each of our LiFePO4 cells comes in 3.0volt configuration. Thus from there we can build your own customized cell in 10, 20 40, 50, 80, 100, 200 Ah, etc.
To fit your specific needs, you can can make 24 volt -- 8 x 3 volt, 36 volt -- 12 x 3 volt, 48 volt -- 16 x 3 volt, etc.
Customized pricing is easy.
It is easy to understand our pricing. Each 3 volt cell is $3.50 per Ah. So if you need 10 Ah, it is $35 for each cell and you need 12 cells (12 x 3 - 36) = $420 each (includes our most advanced battery managment system that handles all current flow, high and low level controls, etc)
This calculation can be done for any different type of LiFePO4 battery configuration. We can even customize size and shape to fit your needs.
