High-voltage and high-current lithium iron phosphate battery energy storage system ushered in a major outbreak after the new crown epidemic

The high-voltage and high-current lithium iron phosphate battery energy storage system ushered in a major outbreak after the new crown epidemic. The time comes to November, and the first half of 2020 has quietly gone far. If we look back over the past few months, it is not difficult to find that the development of the lithium-ion battery industry is like doing sit-ups. On the one hand, due to the cold winter of the auto market and epidemic factors, the entire industry market has shown a serious downward trend; but on the other hand, with the reform and self-help of companies, and the joint assistance of the government and capital, the lithium iron phosphate battery industry has Strong potential broke out again. The high-voltage and high-current lithium iron phosphate battery energy storage system ushered in a major outbreak after the new crown epidemic. As we all know, as a support for the automotive industry, especially new energy vehicles, the power lithium-ion battery industry chain has always been heavily influenced by the auto market. During the Spring Festival every year, due to problems such as insufficient output of workers returning to their hometowns, the auto market is generally sluggish, which has put pressure on the development of the power lithium battery industry. Since the beginning of this year, with the strong impact of the uninvited new crown epidemic, the already sluggish auto market has even worsened. In the case of a large number of car companies' production cliffs and cold sales, the supporting power lithium battery industry has also been affected. Due to the novel coronavirus, the dependence of the energy storage supply chain has now become a hot topic. Although some manufacturers in the United States and Europe promise to process more batteries or lithium iron phosphate battery energy storage systems, most of the world's battery products come from my country, which obviously still dominates the global battery market. After the tightening of South Korea's supply chain in 2018, my country's lithium iron phosphate batteries have once again attracted attention in the US market. The outbreak of this epidemic may reduce my country's battery output, which is expected to decrease by 10% in 2020. All in all, despite the occurrence of the coronavirus business situation, it is expected that the competitiveness of the lithium iron phosphate battery energy storage industry will continue to improve. This is also reflected in analysts’ recent predictions that from now to the end of this century, the price of lithium-ion batteries will It will drop by nearly 50%. With the significant drop in the cost of lithium-ion batteries and the relatively comprehensive performance of lithium-ion batteries, lithium iron phosphate batteries have now become the main force for new energy storage and can play a better regulatory role. Application advantages of lithium iron phosphate batteries in energy storage systems 1. High safety and reliability: Under normal use, the normal service life of the battery is not less than 15 years; in extreme cases, it is in the control range even if a failure occurs , There should be no failures such as explosion and combustion that endanger the safe operation of the power station. 2. Iron phosphate batteries have the advantages of high energy density, long service life, environmental protection, high current charging and discharging, and safety. Although the cost of lithium iron phosphate batteries is higher than that of lead-acid batteries, from the perspective of cost performance, iron phosphate batteries The lithium-ion cycle life is about 6 times that of lead-acid batteries, and the cost of lithium iron phosphate is about one-third of the cost of lead-acid batteries. 3. The lithium iron phosphate battery is small in size and has good charge and discharge characteristics. Although the volume of lithium-ion batteries is only two-thirds of the volume of lead-acid batteries, and the weight is only one-third of the volume of lead-acid batteries, the conversion efficiency of charging and discharging electric energy of lithium-ion batteries can be greater than 97%, and the charging and discharging of lead-acid batteries The energy conversion efficiency is about 80%. At the same temperature, using different rates of discharge current, the discharge output characteristics of a fully charged lithium iron phosphate battery are very stable. At present, the energy density of lithium iron phosphate battery systems can only reach up to 140Wh/Kg. Even though the energy density of lithium iron phosphate and multi-composite lithium ion batteries is increasing, it can only reach up to 140-175Wh/kg. But for passenger cars that do not require high mileage, the energy density currently achieved by lithium iron phosphate batteries can meet their needs. At present, almost all technical routes for supporting batteries in the passenger car field are lithium iron phosphate. Generally speaking, lithium iron phosphate batteries used in the field of energy storage generally require more than 3,500 cycles, that is, the service life of the lithium iron phosphate batteries for energy storage is greater than 10 years. The number of cycles of lithium iron phosphate batteries is much higher than that of lead-acid batteries and ternary batteries, and the number of cycles can reach more than 7,000. Moreover, the current price of lithium iron phosphate batteries is about 0.6/Wh. With the sharp drop in raw material prices and technological progress, the cost-effectiveness of lithium iron phosphate batteries is getting higher and higher, and it is expected to become an important battery supply direction for energy storage in the future. The energy density technology of lithium iron phosphate batteries has been greatly improved. With the trend of policy decline, lithium iron phosphate has gradually been favored due to its own advantages of low cost, high safety, and long life. The pattern of 'the rise of the ternary and the decline of iron lithium ion' may be broken. This is also a major change for the power lithium battery market. With the increasing demand for lithium iron phosphate batteries, the future of lithium iron phosphate batteries The battery market may see a substantial rise. With the outbreak of the 5G base station energy storage market, it is expected that the demand for lithium iron phosphate batteries will rise sharply. It is predicted that the demand for lithium iron phosphate batteries for newly built and renovated 5G base stations in 2020 will reach 10GWh. With the support of domestic grid-side reforms and policies, the turning point of my country's energy storage is at hand. By 2025, consumer-side energy storage can achieve parity in most areas of my country, and the energy storage market space can reach 650 billion yuan. By 2030, the integration of solar storage in most areas of my country can achieve parity, and the energy storage market space can reach more than 1.2 trillion yuan. In the future, lithium iron phosphate batteries will show their talents. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
