Industrial application of energy storage lithium iron phosphate battery
Lithium iron phosphate battery has benefited most from the 100 billion gold mine in the energy storage battery market. The industrial equipment industry has developed rapidly in recent years, and the energy storage field has been closely watched. In the face of huge market demand and potential, domestic energy storage lithium iron phosphate batteries are gaining momentum. The application of energy storage lithium iron phosphate batteries in the industrial field: China’s electricity consumption is huge, and various power generation methods coexist. To realize the rational use and storage of energy in the Chinese power grid system, it is necessary to construct power grids and carry out residual electricity storage. Power grid integration refers to the addition of clean energy, such as intermittent and fluctuating power generated by wind power and solar energy, to the large power grid, thereby widely integrating power from various resources to ensure the stability of power supply. The practice of power companies to use stored energy to meet power demand during peak usage periods is called grid peak shaving, commonly known as 'peak shaving and valley fillingThese applications require tens to hundreds of gigawatt-hours of stored value. In China, the uneven economic development of various regions and the difference in energy demand require more intelligent deployment of electricity production and transmission, and the demand for energy storage will surpass that of Europe. The most common grid storage technology today is pumped water storage, which accounts for nearly 90% of public electricity storage. However, this is restricted by geology and space, and the pumped-storage system takes many years and costs millions of dollars to build. At the same time, pumped storage power is connected to the grid as the final receiving and outputting party of electricity. It relies on the stable transmission of electricity. Different power generation methods require certain conversions to make the current stably integrated into the grid. The conversion of current requires energy storage power stations. The existence of the power station can output smoothly. Such energy storage power stations generally use lithium iron phosphate batteries as energy storage media. The advantage is that the construction time is short, and theoretically, it can be placed anywhere. The usual main application areas of industrial lithium batteries: ⒈The application of electric vehicles For our country, automobile pollution is becoming more and more serious, and the damage to the environment such as exhaust gas and noise has reached the level that it must be controlled and treated. Therefore, lithium-ion batteries have been vigorously developed in the electric vehicle industry due to their pollution-free, low-polluting, and energy-diversified characteristics, so the application of lithium iron phosphate batteries is another good strategy to solve the current situation. ⒉Aerospace applications Due to the advantages of lithium-ion batteries, aerospace organizations also apply lithium-ion batteries to space missions. At present, the main role of lithium-ion batteries in the aviation field is to provide support for launch and flight calibration, and ground operations; at the same time, it is beneficial to improve the efficiency of primary batteries and support night operations. Industrial energy storage is a new growth point in the demand for lithium iron phosphate batteries: the applications of lithium iron phosphate batteries in industrial energy storage include general UPS energy storage power supplies, power tools, industrial machinery, mobile base station power supplies, and wind and solar power generation facilities. Although lead-acid batteries are currently mostly used in energy storage equipment, as lithium battery technology continues to mature, lithium batteries will gradually replace lead-acid batteries. Of the total global demand for lithium iron phosphate batteries in 2012, the industrial energy storage market consumed 4.673 million kWh, accounting for 12.25%. The demand for lithium batteries for power tools in China is slightly larger. The industrial energy storage market consumes 731,500 kWh of lithium-ion batteries. It accounts for 15.65%, which is higher than that of the world. In addition, the mobile base station power supply market has the fastest growth. In 2012, it consumed 58,000 kWh of lithium batteries, a significant increase from 2011. In general, environmental protection and pollution-free industrial lithium batteries are now advocated for large-scale applications. Industrial lithium batteries are widely used due to their advantages such as long life and small size. The total capacity of the industrial energy storage market for lithium iron phosphate batteries is considerable, and the user-side potential is huge.
