Introduction to the characteristics of lithium iron phosphate batteries

The cycle life of a long-life lead-acid battery is about 300 times, and the highest is 500 times. The lithium iron phosphate power lithium battery has a cycle life of more than 2000 times, and the standard charge (5 hour rate) use 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, at most 11.5 years, while lithium iron phosphate batteries will be used for 7-8 years under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries. 2. The use of safe lithium iron phosphate completely solves the safety hazards of lithium cobalt oxide and lithium manganese oxide. Lithium cobalt oxide and lithium manganese oxide will explode in a strong collision and pose a threat to the life and safety of consumers, while lithium iron phosphate After rigorous safety tests, there will be no explosion even in the worst traffic accidents. High current 2C can be charged and discharged quickly. With a dedicated charger, the battery can be fully charged within 40 minutes of 1.5C charging, and the starting current can reach 2C. Lead-acid batteries do not have this performance now. 3. The high temperature resistance 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. The capacity has a larger capacity than ordinary batteries (lead-acid, etc.). Rechargeable batteries work under conditions that are often fully charged and not discharged, 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. 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. The battery does not contain 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. 5. The performance of lithium power lithium battery without memory effect is mainly determined by the positive and negative electrode materials. Lithium iron phosphate has only appeared in recent years as a lithium-ion battery material. The domestic development of large-capacity lithium iron phosphate battery was July 2005. month. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power lithium batteries. 1C charging and discharging cycle life is up to 2000 times. Single-cell battery will not burn or explode when overcharged at 30V. Lithium iron phosphate cathode materials make large-capacity lithium-ion batteries easier to use in series. To meet the requirements of frequent charging and discharging of electric vehicles. It has the advantages of non-toxic, non-polluting, good safety performance, wide source of raw materials, low price, and long life. It is an ideal cathode material for a new generation of lithium-ion batteries. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
