Say Goodbye to old battery technology.

Say hello to the Foxx.

Foxx Lithium Iron

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

The latest in Lithium Chemistry has brought affordability and flexibility 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 available in standard and custom dimensions. Foxx 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 economic 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 Iron Phosphate, has been successfully developed using state of the art technology to prepare lithium in the proper environment.

Foxx Lithium batteries provide a rechargeable, clean, fast and efficient power source that out-performs all others for practical & economical use.

Finally a real-life solution is available for energy demands! Foxx Lithium batteries come in many varied sizes including: New Foxx100 be available in June, 2007. We are currently working on 200 & 300ah cells available in August, 2007. We also can work with the client to provide specific modules in accordance with the application's needs.

BMS (Battery Management System)
Unlike the lead-acid battery, a number of LiFePO4 cells in a battery pack in series connection cannot balance each other during charging process. This is because the charge current stops flowing when the cell is full. This means that the LiFEPO4 packs need management boards.

LiFePO₄ was first introduced as a potential cathode material for Lithium batteries in 1997. Under its pure form, the Olivine-structured material showed specific capacities up to110 mAh/g.

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

There are three types of Lithium ion strategies are 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.

Fast Charging
During the charging process, a conventional Li-ion Battery containing lithium cobalt oxide (LiCoO2) needs two steps to be fully charged: step 1 uses constant current (CC) to get 60% State of Charge (SOC); step 2 takes place when charge voltage reaches 4.2V per cell, which is the upper limit of safe charging voltage. Turning from constant current (CC) to constant voltage (CV) means that the charge current is limited by what the battery will accept at that voltage, so the charging current tapers down asymptotically. To put a clock to the process, step 1 (60%SOC) needs a minimum of two hours and the step 2 (40%SOC) needs another two hours. Because an over voltage can be applied to the LiFePO4 battery it can be charged by only one step of CC to reach 95%SOC or be charged by CC+CV to get 100%SOC. This is similar to the way lead acid batteries are safely force charged. The minimum total charging time will be about one hour.
Large overcharge tolerance and safer performance places the FOXX at the top of battery performance.

Overcharge tolerance and safer performance

A Standard Lithium battery has a very narrow overcharge tolerance, about 0.1V over the 4.2V per cell charging voltage plateau, which also the upper limit of the charge voltage. Continuous charging over 4.3V would either damage the battery performance, such as cycle life, or result in fire or explosion.

A Foxx Lithium battery has a much wider overcharge tolerance of about 0.7V from its charging voltage plateau of 3.5V per cell. When measured with a differential scanning calorimeter (DSC) the exothermic heat of the chemical reaction with electrolyte after overcharge is only 90 Joules/gram for LiFePO4 versus 1600 J/g for LiCoO2 . The greater the exothermic heat, the more vigorous the fire or explosion that can happen when the battery is abused.

A LiFePO4 battery can be safely overcharged up to 30V without protection circuit board. It is therefore suitable for large capacity and high power applications. From the viewpoint of large overcharge tolerance and safety performance, a LiFePO4 battery is similar to a lead-acid battery.

The safety characteristics inherent to Foxx Lithium 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, Foxx batteries possess safety characteristics that are fundamentally superior to those of Lithium-ion batteries made with other cathode materials. Fox Lithium batteries do not contain any heavy metals, and does not exhibit the "memory effect" of Nickel-Cadmium and Nickel-metal Hydride solutions. Foxx technology demonstrates excellent shelf life, long cycle life and is maintenance free. Another key benefit 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.

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.

Foxx Lithium Batteries bring to market 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.

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, Foxx Lithium batteries can be easily modified to meet the specific requirements of varied applications-extremely flexible in design capabilities.

We are currently supplying Foxx lithium batteries for the electrical bicycle and scooter industry, as well as some emerging 3 & 4 wheel alternative 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 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 Foxx Lithium battery.

of phosphates, makes Foxx Lithium 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.

Innovation in Li-ion Battery
LiFePO4 Power Battery: Faster charging and safer performance

It is clear that the small capacity Li-ion (polymer) Battery containing lithium cobalt oxide (LiCoO2) offers a genuinely viable option for electronics and digital applications. However, lithium cobalt oxide (LiCoO2) is very expensive and un-safe for large capacity Li-ion Battery. Recently lithium iron phosphate (LiFePO4) has been becoming "best-choice" materials in commercial Li-ion (polymer) Batteries for large capacity and high power applications, such as lap-top, power tools, e-wheel chair, e-bike, e-car and e-bus. A LiFePO4 battery has hybrid characters: as safe as lead-acid battery and as powerful as lithium ion cells. The advantages of large format Li-ion (polymer) batteries containing lithium iron phosphate (LiFePO4) are listed as below:

1. Fast charging:
During charging process, a conventional Li-ion Battery containing lithium cobalt oxide (LiCoO2) needs two steps to be fully charged: step 1 is using constant current (CC) to get 60% State of Charge (SOC); step 2 takes place when charge voltage reaches 4.2V, upper limit of charging voltage, turning from CC to constant voltage (CV) while the charging current is taping down. The step 1 (60%SOC) needs two hours and the step 2 (40%SOC) needs another two hours. LiFePO4 battery can be charged by only one step of CC to reach 95%SOC or be charged by CC+CV to get 100%SOC. The total charging time will be two hours.

2. Large overcharge tolerance and safer performance
A LiCoO2 battery has a very narrow overcharge tolerance, about 0.1V over 4.2V of charging voltage plateau and upper limit of charge voltage. Continuous charging over 4.3V would either damage the battery performance, such as cycle life, or result in firing and explosion. A LiFePO4 battery has a much wider overcharge tolerance of about 0.7V from its charging voltage plateau 3.4V. Exothermic heat of chemical reaction with electrolyte measured by DSC after overcharge is only 90J/g for LiFePO4 verse 1600J/g for LiCoO2 . The more is the exothermic heat, the larger energy heating up the battery in its abusive condition, the more chance toward firing and explosion. A LiFePO4 battery would be overcharged up to 30V without protection circuit board. It is suitable for large capacity and high power applications. From viewpoint of large overcharge tolerance and safety performance, a LiFePO4 battery is similar to lead-acid battery.

3. Self balance
Alike lead-acid battery, a number of LiFePO4 cells in a battery pack in series connection would balance each other during charging process, due to large overcharge tolerance. This self balance character can allow 10% difference between cells for both voltage and capacity inconsistency.

4. Simplifying battery management system (BMS) and battery charger
Large overcharge tolerance and self-balance character of LiFePO4 battery would simplify battery protection and balance circuit boards, lowering their cost. One step charging process would allow to use simpler conventional power supplier to charge LiFePO4 battery instead to use a expensive professional Li-ion battery charger.

5. Longer cycle life
In comparison with LiCoO2 battery which has a cycle life of 400 cycles, LiFePO4 battery extends its cycle life up to 2000 cycles.

6. High temperature performance
It is detrimental to have a LiCoO2 battery working at elevated temperature, such as 60C.. However, a LiFePO4 battery runs better at elevated temperature, offering 10% more capacity, due to higher lithium ionic conductivity.

1.5C charge / 2C discharge (25℃)

When phosphate batteries are overcharged over 3A 5V, the temperature 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.

As a new anode material for Lithium-ion batteries, LiFePO4, was first introduced in 1997, and has continually improved until the present as the very best option for smart, clean power. It has drawn attention from world experts due to its’ reliable safety, long life, low environmental impact, and its charge and discharge characteristics. Foxx Lithium batteries (LiFePO4) are by far the best options for smart, clean power. Useful for consumer, commercial and military applications, our Foxx batteries use no heavy metals, making these the premiere “Green Power Source”. They have extremely long life yielding up to 2000 cycles, high effective discharge capabilities, low internal resistance, and extreme stability. Foxx batteries are maintenance free, have no memory effect, and withstand large fluctuations in temperature.

Foxx cells are intrinsically safe and eliminate the risk of explosions and thermal runaway associated with conventional Lithium-Ion batteries that use oxide active materials. To achieve this, the active materials in Foxx technology are not combustible and do not release oxygen if exposed to high temperature or in the event of battery failure or mechanical abuse.

Foxx materials are designed to ensure all the Lithium is fully extracted from the cathode when the battery is fully charged. As a result safety issues relating to overcharge are eliminated because there is no Lithium available to plate on the anode in an overcharged state. This is in contrast to conventional Li Ion cells, which only extract half their Lithium content when they reach their upper cut-off voltage. Conventional Li Ion cells are easy to overcharge and once in this state they can continue to extract Lithium putting the cell in a dangerous mode and making it prone to fires and explosions.

Foxx Lithium uses patent pending laser-welded multi-plate prismatic construction that is vibration and abuse tolerant. This design offers unsurpassed hermetic sealing with the lowest internal resistance, a key benefit for mission critical and medical devices or applications requiring extreme calendar life such as Hybrid Electric Vehicles.

While other battery technologies like NiCd and traditional Lithium-Ion employ heavy metals and elements that are known to be highly toxic or potential carcinogens. Foxx cells do not contain heavy metals and are environmentally friendly.

Foxx batteries are replacing the lead acid, hydrogen, nickel metal hydride, and existing lithium cobalt/manganese based methods as the smartest and most economical power option.

Through intelligent design and application of these new technologies, together we can help our planet remain green, and enjoy a great quality of life. Cooperation, integrity and creativity are the Aten Energy principles that guide us to a focused approach to excellent customer service. We consider our customers needs with all of our heart and soul.
