A lithium iron phosphate battery
is a lithium-ion battery with lithium iron phosphate as the positive electrode. Different from other types of lithium batteries, lithium iron phosphate battery has the characteristics of many cycles, low cost, and high safety due to its special materials.
Since 2010, the market demand for electric vehicles has grown rapidly, driving the cost of lithium batteries down by more than 85%. In 2020, the first phase of the Fujian Jinjiang energy storage power station pilot project (30 MW/108 MW· h) with lithium iron phosphate batteries as the energy storage battery was successfully connected to the grid, and the demand for energy storage base stations proposed by the three major operators in the communication industry, etc. A series of beneficial attempts have made the business model of lithium iron phosphate batteries increasingly clear, and the development prospects are gradually becoming clearer.
With the widening of application scope and scenarios, the role of battery safety protection and management system is prominent. Lithium iron phosphate batteries need corresponding battery management systems, safety protection systems, and related policies and standards to ensure their development in construction and application. In this regard, this paper summarizes the status of lithium iron phosphate batteries, and introduces the application of existing lithium iron phosphate batteries, hoping to provide some reference for the development of lithium iron phosphate batteries in the future.
1 Application status of lithium iron phosphate battery
At present, electrochemical energy storage mainly uses lithium batteries and lead batteries. Among them, lithium iron phosphate batteries have been widely used in 5G base stations, electric vehicles, and energy storage power stations due to their high operating voltage, high energy density, long cycle life, good safety performance, and low self-discharge rate, and no memory effect. in the scene. The state ensures the stable and orderly development of lithium iron phosphate batteries by promulgating policies and formulating standards.
Supporting policies and specifications compared with ternary lithium batteries, the cost advantage of lithium iron phosphate batteries is more obvious. The "Notice on Organizing and Implementing New Infrastructure Construction Projects (Broadband Networks and 5G Fields) in 2020" issued by the National Development and Reform Commission and the Ministry of Industry and Information Technology clearly stated that 5G is an important part of new infrastructure construction. There is huge potential in consumption, upgrading, and cultivating new kinetic energy. Promoting the use of lithium iron phosphate batteries in communication base stations has positive significance for promoting the green and high-quality development of the communication industry.
In December 2018, the Hebei Provincial Department of Industry and Information Technology issued the "Notice on the Release of the "Beijing-Tianjin-Hebei Region New Energy Vehicle Power Battery Recycling Pilot Implementation Plan" and the Collection of Pilot Demonstration Projects. China Tower Corporation launched a pilot project.
The "Guiding Opinions on the Promotion and Application of Lithium Iron Phosphate Batteries" issued by China Mobile in 2018 proposed to promote the application of lithium iron phosphate batteries in various base stations, aggregation equipment rooms, and important end nodes. With the promulgation of national policies, various industries and localities have set up standards to strengthen the control and development of lithium iron phosphate batteries, and clearly put forward the technical specifications and requirements for lithium iron phosphate batteries to be used in various scenarios.
2 Lithium iron phosphate battery application
In recent years, lithium iron phosphate batteries have been widely used in the construction of 5G base stations, new energy electric vehicles, and energy storage power stations.
The demand for 5G base stations provides a development opportunity for the development of lithium iron phosphate batteries. Due to the increase in the overall power consumption of 5G base stations, the power supply system must be expanded, which means that the power supply must be guaranteed through transformation. In addition, the safety of energy storage batteries needs to be considered. The lithium iron phosphate battery with high safety, high energy ratio, small size, lightweight, and long life just meets the needs of 5G base stations.
Since 2020, the demand for lithium iron phosphate batteries has risen. With the improvement of various models of new energy vehicles, lithium iron phosphate batteries have occupied a place in the industry. For example, BYD has now become the world's largest supplier of lithium iron phosphate batteries, its battery technology has been recognized by the world, and has established contacts and cooperation with many global heavyweight car manufacturers including Daimler, Toyota, etc.
In 2020, the launch of "blade battery" once again attracted global attention, promoting domestic lithium iron phosphate batteries to go international. Compared with electric vehicles, the application of electric ships is more advanced in modern technology. The electric ship "Junlv" uses a matching lithium iron phosphate battery. Compared with fuel-powered ships of the same size, it can save nearly 100 tons of fuel every year. The emission of waste pollutants such as carbon and sulfur has the advantages of high power, high energy efficiency, and high cleanliness. Its battery capacity is equivalent to the battery capacity of 50 pure electric vehicles. It can be charged for 4~5 hours at night to meet the requirements of 8 hours during the day. battery life requirements.
As an energy storage battery, lithium iron phosphate batteries are used in energy storage power stations across the country. Due to the wide application of lithium iron phosphate batteries, the supporting battery management technology, and safety protection technology have become the current key research and development issues.
The above describes the development status and application of lithium iron phosphate batteries in detail. If you want to know more or want to buy lithium iron phosphate batteries, please contact us
