Lithium iron phosphate battery and its characteristics analysis

Lithium iron phosphate battery refers to a lithium battery that uses lithium iron phosphate as a positive electrode material. There are many kinds of cathode materials for lithium batteries, including lithium cobalt oxide, lithium manganate, lithium nickelate, ternary materials, and lithium iron phosphate. Among them, lithium cobalt oxide is currently the cathode material used in most lithium batteries, while other cathode materials have not been processed in large quantities on the market due to a variety of reasons. Lithium iron phosphate is also one of the lithium batteries. In terms of material principle, lithium iron phosphate is also an intercalation/deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate. Lithium iron phosphate batteries are used to make lithium secondary batteries. The current important direction is power lithium-ion batteries, which have great advantages over NI-MH and Ni-Cd batteries. The characteristics of lithium iron phosphate batteries 1. Ultra-long life long-life lead-acid batteries have a cycle life of about 300 times, and the highest is 500 times, while lithium iron phosphate power lithium-ion batteries have a cycle life of more than 2000 times. Standard charging (5 Hour rate) can be used up to 2000 times. Lead-acid batteries of the same quality are new half a year, half a year old, and half a year for maintenance, 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 under a strong collision and pose a threat to the lives of consumers, while lithium iron phosphate With strict safety detection, there will be no explosion even in the worst traffic accidents. High current 2C can be quickly charged and discharged. Under the special charger, the battery can be overflowed within 40 minutes of 1.5C charging, and the starting current can reach 2C. Lead-acid batteries currently have no such performance. 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℃. The working temperature range is wide (-20C--+75C), with high temperature resistance, the lithium iron phosphate electric heating peak can reach 350℃500℃, while the 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 overflowing, and their capacity will quickly fall below the rated capacity. 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 a lithium iron phosphate battery of the same specification and capacity is 2/3 of the volume of a lead-acid battery and its weight is 1/3 of that of a 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), non-polluting, in line with European RoHS regulations, and is an absolute green battery certificate. 5. The performance of lithium-ion battery without memory effect depends critically on the positive and negative electrode materials. Lithium iron phosphate has only appeared in recent years as a lithium battery material. The domestic development of large-capacity lithium iron phosphate batteries was July 2005 . Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power lithium-ion 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 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 batteries. The positive electrode of the lithium battery is lithium iron phosphate material. This new material is not the previous lithium battery cathode material LiCoO2; LiMn2O4; LiNiMO2. Its safety performance and cycle life are unmatched by other materials, and these are also the most important technical indicators of power lithium-ion batteries. 1C charging and discharging cycle life is up to 2000 times. Single-cell battery will not burn or explode if the overcharge voltage is 30V. Piercing does not explode. Lithium iron phosphate cathode material makes it easier to connect in series to make large-capacity lithium batteries.
