The LiFePO4 battery refers to a Li-ion battery that takes LiFePO4 as its positive electrode material. The popular positive electrode materials of Li-ion batteries mainly include lithium cobaltate, lithium manganate, lithium nickelate, ASP cathode materials, and the like. In the battery market, Compared with them, the LiFePO4 battery now has many advantages, and it is widely used in:
1. Large electric vehicles: buses, electric cars, scenic tour buses and hybrid vehicles;
2. Light electric vehicles: electric bicycles, forklifts, cleaning vehicles, electric wheelchairs, etc.;
3. Power tools: electric drills, chainsaws, etc.;
4. Toys: remote control cars, boats, airplanes;
5. Solar energy storage and wind power generation equipment;
6. UPS and emergency lights, warning lights and miner’s lights
7. Small medical equipment, etc.
The P-O bond in the LiFePO4 is stable and difficult to break. Unlike lithium cobaltate, it does not become hot or form strong oxidizing substances at high temperatures or during overcharging. Besides, LiFePO4 battery has a high decomposition temperature of about 600 ° C, so its overcharging safety is much higher than ordinary liquid batteries such as lithium cobalt oxide batteries.
Long service life
The lead-acid battery has a cycle life of about 300 times and a maximum of about 500 times. By contrast, the LiFePO4 battery has a cycle life of more than 2,000 times. And A lead-acid battery of can be used for 1 to 1.5 years, while a LiFePO4 battery has a theoretical life of 7 to 8 years under the same conditions. Comprehensively, the performance price ratio is theoretically more than four times that of lead-acid batteries.
Wider operating temperature range & Large capacity
Its workable environment temperature range is about from -20℃ to +75℃, which is much wider than other batteries. Moreover, it is known from the energy density of the battery that the lead-acid battery is about 40 WH/kg, and the mainstream LiFePO4 battery on the market has an energy density of 90 WH/kg or more.
No memory effect
Rechargeable batteries work under conditions that are often not fully discharged, and the capacity will quickly fall below the rated capacity. This phenomenon is called the memory effect. Generally, Nickel-metal hydride and nickel-cadmium batteries have a memory effect, while lithium-iron phosphate batteries do not. The battery needn’t to be discharged fully before charging.
Lightweight + Eco-friendly
The volume of the lithium iron phosphate battery of the same capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of that of the lead-acid battery. Moreover, the LiFePO4 battery is considered to be free of any heavy metals and rare metals (Ni-MH batteries contain such metals). And it is non-toxic (SGS certified), non-polluting, in line with European ROHS regulations. Therefore, it is a green battery.
GeePower Energy Technology Co., Ltd. was founded in the early 1982s for producing battery raw materials and started to produce batteries in 1988. After 36years of development, we have grown to become a professional manufacturer of rechargeable batteries including LiFePO4 batteries, Li-NiCoMn batteries, pouch cells and so on. We enjoy a high reputation and are fully experienced in this field.
