Under what circumstances will we choose lithium iron phosphate battery?

When we design matching batteries for electronic equipment, we need to consider many factors, especially in some equipment devices that will affect the safety of operators. Designers have many considerations in battery chemical composition, size, power consumption, cost and safety. Our primary goal is to consider the needs of users, and based on these choices, we can ensure the battery performance requirements within an acceptable cost range. This is a qualified manufacturing process. Traditional lithium ion batteries use excessive metal oxides as cathode materials, such as lithium cobalt oxide or lithium nickel cobalt aluminum oxide. The lithium iron phosphate battery uses lithium iron phosphate as the positive electrode to charge the rechargeable lithium ion battery. This low-cost mineral provides excellent thermal stability, fast charging time and long cycle life through natural chemical reaction, but it has some energy loss because its working voltage is lower than that of standard lithium ion components. The first application of lithium iron phosphate material in lithium ion batteries was invented by Dr. Goudreau in 1997, and has applied for its patent. Lithium ferrous phosphate has been studied in various application fields, including power grid stability, power tools, hybrid electric vehicles, lasers, naval combat aircraft and helicopters. The advantages and disadvantages of replacing standard lithium ion (metal oxide cathode material) with lithium ferrous phosphate are obvious. How to make the best choice for the application? It all depends on what kind of performance, security and cost you want to achieve. Figure 1 100A The discharge curve of calcium phosphate at different temperatures is like weighing the advantages and disadvantages of anything else. Compared with the traditional lithium ion metal oxides, the chemical properties of iron phosphate have its unique advantages, such as lighter weight, more energy in relative volume, stable chemical properties at high temperature and safe storage (better than lead acid, nickel cadmium or nickel hydrogen), but its performance at low temperature is poor. Interestingly, the flat voltage performance curve of iron phosphate is both its advantages and disadvantages for designers. On the positive side, the battery provides stable energy transmission power, and over 80% SOC and Wally discharge have little influence on its performance. If it is in a low-pressure environment, this energy can be used effectively to the maximum extent. However, because the SOC index of battery voltage has energy surplus in lithium-ion metal oxides, if a controllable lithium iron phosphate battery is set, this circuit will undoubtedly be much more complicated. Although there are some obvious shortcomings in iron phosphate technology, scientists hope to research and develop it to overcome or avoid these shortcomings, so some battery manufacturers have formulated energy replay standards that compete with lithium iron phosphate technology to improve its utilization efficiency. For example, calcium superphosphate is a patent that Saft Company is applying for, which is based on the safety, power and capacity of iron phosphate chemicals. Iron phosphate battery contains lithium-nickel-cobalt-aluminum oxide battery with the same standard lithium ion chemistry as saft, so superphosphate can be converted by traditional lithium ion or lithium-iron phosphate system in most applications. Compared with the standard lithium iron phosphate battery, super iron phosphate technology has reliable safety, long cycle life, longer service life and wider working temperature range, including superior low-temperature environmental performance. In addition, the battery cell has good anti-abuse performance and can be charged safely and stably under the condition of floating voltage.
