Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as the positive electrode material. Lithium iron phosphate battery has the advantages of high working voltage, high energy density, long cycle life, good safety performance, small self-discharge rate, and no memory effect. So what are the advantages of lithium iron phosphate batteries in the energy storage market?
Lithium iron phosphate battery has a series of unique advantages such as high working voltage, high energy density, long cycle life, low self-discharge rate, no memory effect, green environmental protection, etc., and supports stepless expansion, suitable for large-scale electric energy storage, in renewable Energy, power station power generation, safe grid connection, grid peak regulation, distributed power station, UPS power supply, emergency power supply system and other fields have good application prospects.
1. Wind power generation, photovoltaic power generation and other renewable energy generation for lithium iron phosphate battery application are safely connected to the grid
The inherent randomness, intermittency, and volatility of wind power generation determine that its large-scale development will inevitably have a significant impact on the safe operation of the power system. With the rapid development of the wind power industry, especially most wind farms belong to “large-scale centralized development and long-distance transmission”, the grid-connected power generation of large wind farms poses severe challenges to the operation and control of large power grids. Photovoltaic power generation is affected by ambient temperature, sunlight intensity and weather conditions, and photovoltaic power generation presents the characteristics of random fluctuations.
Therefore, large-capacity energy storage products have become a key factor in solving the contradiction between power grids and renewable energy power generation. The lithium iron phosphate battery energy storage system has the characteristics of fast switching of working conditions, flexible operation mode, high efficiency, safety and environmental protection, and strong scalability. Local voltage control issues, improving the reliability of renewable energy power generation and improving power quality, making renewable energy a continuous and stable power supply.
With the continuous expansion of capacity and scale and the continuous maturity of integrated technology, the cost of energy storage systems will be further reduced. After long-term tests of safety and reliability, lithium iron phosphate battery energy storage systems are expected to be used in renewable energy such as wind power generation and photovoltaic power generation. It has been widely used in safe grid connection of energy generation and improvement of power quality.
2. Power grid peak regulation for lithium iron phosphate battery application
The main means of grid peak regulation has always been pumped storage power plants. Since the pumped storage power station needs to build two reservoirs, the upper and lower reservoirs, which are limited by geographical conditions, it is not easy to build in plain areas, and it occupies a large area and the maintenance cost is high. The lithium iron phosphate battery energy storage system is used to replace the pumped storage power station to cope with the peak load of the power grid. It is not restricted by geographical conditions, the location is free, the investment is small, the land occupation is small, and the maintenance cost is low. It will play an important role in the peak shaving process of the power grid.
3. Distributed power station for lithium iron phosphate battery application
Due to the defects of the large-scale power grid itself, it is difficult to guarantee the quality, efficiency, safety and reliability requirements of power supply. For important units and enterprises, dual power supplies or even multiple power supplies are often required as backup and protection. The lithium iron phosphate battery energy storage system can reduce or avoid power outages caused by grid failures and various unexpected events, playing an important role in ensuring safe and reliable power supply for hospitals, banks, command and control centers, data processing centers, chemical material industries, and precision manufacturing industries.
4. UPS power supply for lithium iron phosphate battery application
The sustained and rapid economic development has brought about decentralized demand for UPS power users, making more industries and more enterprises have a continuous demand for UPS power. Compared with lead-acid batteries, lithium iron phosphate batteries have the advantages of long cycle life, safety and stability, environmental protection, and low self-discharge rate. With the continuous maturity of integrated technology and the continuous reduction of costs, lithium iron phosphate batteries will be widely used in UPS power batteries.
