Product Description
Everyone knows that lithium batteries can explode, but it's really difficult for you to explode lithium iron phosphate batteries. Here's some knowledge about lithium iron phosphate batteries.
What is LiFePO4 Battery? The lithium iron phosphate (LiFePO4) battery, also called LFP battery (with "LFP" standing for "lithium ferrophosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material. LiFePO4 batteries have somewhat lower energy density than the more common lithium cobalt oxide (LiCoO2) design found in consumer electronics, but offer longer lifetimes, better power density (the rate that energy can be drawn from them) and are inherently safer. LiFePO4 is finding a number of roles in vehicle use and backup power.
History
LiFePO4 is a natural mineral of the olivine family (triphylite). Its use as a battery electrode which was first described in published literature by John B. Goodenough's research group at the University of Texas in 1996, as a cathode material for rechargeable lithium batteries. Because of its low cost, non-toxicity, the natural abundance of iron, its excellent thermal stability, safety characteristics, electrochemical performance, and specific capacity (170 mA·h/g, or 610 C/g) it gained some market acceptance.The chief barrier to commercialization was its intrinsically low electrical conductivity. This problem was overcome by reducing the particle size, coating the LiFePO4 particles with conductive materials such as carbon, or both. This approach was developed by Michel Armand and his coworkers. Another approach by Yet Ming Chiang's group consisted of doping LFP with cations of materials such as aluminium, niobium, and zirconium. Products are now in mass production and are used in industrial products by major corporations including Black and Decker's DeWalt brand, the Fisker Karma, Daimler AG, Cessna and BAE Systems. MIT introduced a new coating that allows the ions to move more easily within the battery. The "Beltway Battery" utilizes a bypass system that allows the lithium ions to enter and leave the electrodes at a speed great enough to fully charge a battery in under a minute. The scientists discovered that by coating lithium iron phosphate particles in a glassy material called lithium pyrophosphate, ions bypass the channels and move faster than in other batteries. Rechargeable batteries store and discharge energy as charged atoms (ions) are moved between two electrodes, the anode and the cathode. Their charge and discharge rate are restricted by the speed with which these ions move. Such technology could reduce the weight and size of the batteries. A small prototype battery cell has been developed that can fully charge in 10 to 20 seconds, compared with six minutes for standard battery cells.

FAQ:1. Q: Do you have current sample in stock?
A: Usually we don't have, because different customers have different requests, even the voltage and capacity are the same, other parameters maybe different. But we could finish your sample quickly once order confirmed.
2. Q: What's the delivery time for mass production?
A: Usually 25-32days, it depends on the quantity, material, battery cell model and so on, we suggest to check delivery time case by case.
3. Q: What kind of certificates could you provide for the battery?
A: It's custom-making design, no current certificate, but we could apply CE, UL, UN38.3 and other related certificates for you, but the certificates fee needs to be paid by you, if your quantity is big enough, certificates fee could be refunded.
4. Q: Do you offer charger for battery?
A: Yes, we do. If you also need charger, please mention it when sending inquiry, kindly note that our charger cost is not included in the battery cost.
5. Q: Are you manufacturer or simply trading company?
A: We are manufacturer, and we sincerely welcome you to visit our factory!
