Abstract The technology of lithium iron phosphate batteries is increasingly becoming developed and stable as a result of the new energy sector’s quick and steady development. With its unique performance advantages and characteristics, lithium iron phosphate battery occupies a large market share and has a wide range of application scenarios. This paper analyzes the specific application scenarios of lithium iron phosphate batteries in the field of transportation and derives the specific performance advantages of lithium iron phosphate batteries. Lithium iron phosphate battery has high energy density, high safety, high cycle life, high-temperature adaptability and other performance advantages. In addition, Lithium iron phosphate batteries are also inexpensive and kind to the environment. Therefore, lithium iron phosphate batteries can better meet the demand for battery applications in the field of transportation. At the same time, these advantages also make the lithium iron phosphate battery in other areas such as communication energy storage and peak energy storage have a high application value. By specifically studying the advantages of lithium iron phosphate, I believe that we can further promote the market application of lithium iron phosphate batteries and provide a method of reference for other batteries.
