What are the seven advantages of lithium iron phosphate batteries?

1. Improvement of safety performance. The PO bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and heat up or form strong oxidizing substances in the same structure as lithium cobalt oxide, so it has good safety. Sex. A report pointed out that in actual operation, a small part of samples were found to burn in acupuncture or short-circuit experiments, but no explosion occurred. In the overcharge experiment, high voltage charging that was several times higher than the self-discharge voltage was used, and it was found Explosion phenomenon. Nevertheless, its overcharge safety has been greatly improved compared with ordinary liquid electrolyte lithium cobalt oxide batteries. 2. Improved lifespan Lithium iron phosphate battery refers to a lithium battery that uses lithium iron phosphate as a positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the highest is 500 times, while the cycle life of lithium iron phosphate power lithium-ion batteries can reach more than 2000 times, and the standard charge (5 hour rate) can reach 2000 times. Lead-acid batteries of the same quality are new for half a year, old for half a year, and for maintenance and maintenance for half a year, which is at most 1 to 1.5 years. When used under the same conditions, lithium iron phosphate batteries have a theoretical life span of 7 to 8 years. Comprehensive consideration, the performance-price ratio is theoretically more than 4 times that of lead-acid batteries. High-current discharge can quickly charge and discharge high-current 2C. Under the special charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C, but the lead-acid battery does not have this performance. 3. Good high-temperature performance. The peak value of lithium iron phosphate electric heating can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20C--75C), with high temperature resistance, lithium iron phosphate electric heating peak can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. 4. Large-capacity ∩ rechargeable batteries work under the condition that they are often fully charged, and the capacity will quickly fall below the rated capacity value. This phenomenon is called the memory effect. Like nickel-metal hydride and nickel-cadmium batteries, there is memory, but lithium iron phosphate batteries do not have this phenomenon. No matter what state the battery is in, it can be charged and used without having to discharge it first. 6. Light weight, the volume of the lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery. 7. The environmental protection lithium iron phosphate battery is generally considered to be free of any heavy metals and Rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), no pollution, in line with European RoHS regulations, is an absolute green battery certificate. Therefore, the reason why lithium batteries are favored by the industry is important because of environmental protection considerations. Therefore, the battery has been included in the 863 National High-tech Development Plan during the Tenth Five-Year Plan and has become a key national support and encouragement project. With my country's accession to the WTO, my country's export of electric bicycles will increase rapidly, and electric bicycles entering Europe and the United States have been required to be equipped with pollution-free batteries.
