...hipower liFepo4

Through exciting innovation and research, we have been able to develop the most advanced battery source the world has seen: Hipower LiFePo4 batteries.

The latest in Lithium Chemistry has brought affordability and flexi-bility to standard and emerging applications. After developing the latest process for treatment of the lithium cathodes with non-toxic enhancers, conductivity has been increased over 10 million times, providing a safe, efficient, rapid-charge power source that is avai-lable in standard and custom dimensions. Hipower LiFePo4 batteries enjoy a flexibility of design that allows for custom battery packs, tailored to meet the design requirements of industry professionals and providing freedom from typical battery size restrictions.

Due to the vulnerability of fossil fuel, and environmental concerns, the alternative energy fields and related industries are rapidly growing at strong rates. In response, renewable energy has attracted more and more attention. This has caused a strong demand of smart, affordable rechargeable batteries. However, the existing lithium ion cell systems, including lithium cobalt oxide and lithium manganese oxide still suffer from low discharge rates, safety concerns, and short cycle life. To solve those issues, a new battery technology, Lithium

LiFePO4 was first introduced as a potential cathode material for Lithium batteries in 1999. Under its pure form, the Olivine-structured material showed specific capacities up to170 mAh/g.

Introducing Nano-painting of LiFePO4 with a Carbon electronic conductor, HiPower Lithium produced cathode mate-rial with specific capacities as high as 165 mAh/g, very close to the maximum theoretical capacity of 170 mAh/g.

Lead Acid: though lower in cost and safety acceptable; it is extremely toxic, the worst for the environment, short cycle life, heavy in weight, not the best choice for many reasons.

Nickel Hydride: exhibits low Power Weight Density, decays faster in high temperature, has memory effect, not suitable for high output usage.

The Lithium Iron Phosphate Battery has been proven as the most environmental friendly battery. It is the safest with longest life cycle and most suitable for high output usage. It is also the best for storage and back-up applications.

There are three types of lithium ion strategies based on different cathode materials. They are: Lithium cobalt oxide, Lithium manganese oxide, and Lithium iron phosphate types. Although Lithium cobalt oxide has the advantage of high energy density, it suffers from safety concerns. Lithium manganese oxide has been evaluated for applications requiring high demands, and has outperformed the previous Lithium strategies. Also, its poor high temperature performance is a major drawback.

Lithium iron phosphate has the best safety characteristics, long cycle life (up to 2000 cycles), and substantial availability. It is well suited for high discharge rate requirements such as the demands of the Military, Electrical Vehicles, Power tools, Mobile needs, UPS (Interrupt/Back-Up) and Solar energy systems.

SaFet y FirSt

The safety characteristics inherent to LiFePo4 technology result from the incorporation of phosphates as the cathode material. Phosphates are ex-tremely 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, Hipower LiFePo4 batteries possess safety characteristics that are fundamentally superior to those of Lithium-ion batteries made with other cathode materials. Hipower Lithium batteries do not contain any heavy metals, and does not exhibit the "memory effect" of Nickel-Cadmium and Nickel-metal Hydride solutions. Hipower LiFePo4 technology demonstrates excellent shelf life, long cycle life and is maintenance free.

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 Com-mission 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.

Hipower LiFePo4 Batteries bring to market the only safe large format lithium-ion rechargeable battery technology. Please call us regarding your particular needs, and would be honored to provide you with smart alternatives.

Flexibilit y

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, According to different applications, Hipower LiFePo4 batteries can be easily modified to meet the specific re-quirements of varied applications-extremely flexible in design capabilities.

current trendS

We are currently supplying Hipower LiFePo4 lithium batteries for the electrical bicycle and scooter industry, as well as some emerging 4 wheel al-ternative vehicles. With over 3,000,000 electric bicycles in use with standard lead acid batteries, it is apparent that the short life span and toxicity from disposal of SLA batteries is a severe problem. Weighing over 12 Kgs, lasting only 6-12 months, and having total energy density of 360 watt hours, the standard 36 volt/10ah SLA battery pack has not proven effective as a smart, clean power source. Furthermore, these conditions have lead to many cities restricting the use of the electric bicycle. The choice is clear for the cleanest, smartest Lithium Power Option, the Hipower LiFePo4 Lithium battery. Options give you Power!

Our latest generation product, the UPS power station, is by far the best solution to sensitive and crucial energy provision. Nothing comes close to the stability and hi-discharge capabilities of our Hipower LiFePo4 batteries, clearly the best choice for industry professional. Ideal for both military back-up sback-upply, our batteries provide the highest quality assurance for high-level commercial use.

The advantages of traditional Lithium-ion coupled with the safety featu-res of phosphates, makes Hipower LiFePo4 the 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.

When phosphate batteries are overcharged over 3A 5V, the tempe-rature of the battery does not surpass 55°C-the battery is extremely safe. After heat tests for 7-8 hours reached 300°C in a hot box process, battery temperature remained nearly the equivalent of the surrounding temperature of hot box, and thermal runaway does not occur- after extrusion or acupuncture, the battery temperature did not surpass 110°C. The safety of the lithium battery is guaranteed by using LiFePO4 as an anode pole. LiFePO4 is one kind of phosphate gathering 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.
