Say goodbye to lead-acid batteries and start the era of lithium iron phosphate battery backup

Say goodbye to lead-acid batteries and start the era of lithium iron phosphate battery backup. The future direction of lithium iron phosphate batteries is 'attractiveAs one of the most popular batteries for new energy batteries, lithium iron phosphate batteries have a broad future. In order to occupy the leading position in the future new energy battery market, major lithium-ion battery companies have stepped up to develop new technologies for lithium iron phosphate batteries, constantly breaking through the technical bottleneck. It is foreseeable that the lithium iron phosphate battery market may usher in an all-round rise in the future. Say goodbye to lead-acid batteries and start the era of lithium iron phosphate battery backup. Due to policy support for new energy vehicles with long-lasting and high-density batteries, subsidies have also increased accordingly, leading most battery companies to develop ternary lithium-ion batteries. As the Chinese government began to reduce subsidies for new energy vehicles in mid-2019, and the frequent occurrence of ternary lithium-ion battery accidents, the market's interest in lithium iron phosphate batteries has risen again. At present, domestic lithium-ion batteries used in energy storage are still dominated by lithium iron phosphate. This time, the domestic grid energy storage demand has exploded, which will directly drive the demand for lithium iron phosphate batteries. The important reasons are: first, the outbreak of grid energy storage demand has provided a way out for lithium iron phosphate batteries that cannot meet the new energy vehicle subsidy policy; second, with recent years, power lithium battery companies have been in technology, cost, etc. In terms of development, lithium iron phosphate batteries have cost-effective advantages compared to lead-acid and lead-carbon batteries. Advantages of lithium iron phosphate batteries ①Safety and environmental protection: Lithium iron phosphate batteries do not contain any heavy metals and rare metals, are safe, non-toxic and pollution-free, and are absolutely green and environmentally friendly batteries. Since the lithium iron phosphate material is clean and non-toxic during the entire processing process, all raw materials are non-toxic and non-polluting. ②Good safety performance: The electrochemical performance of the positive electrode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charging and discharging platform. Therefore, the structure of the battery will not change during the charging and discharging process, and it will not burn and explode. Even under special conditions such as short circuit, overcharge, squeeze, and acupuncture, it is still very safe. ③Small size, good charge-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 charge-discharge power of lithium-ion batteries can be greater than 97 %, and the charge and discharge energy conversion efficiency of lead-acid batteries is about 80%. Regarding the same, 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. ④ High ambient temperature tolerance: When used in outdoor stations, lead-acid batteries must be installed in a holding cabinet. In areas with particularly harsh weather conditions, they must be buried under frozen soil, which will cause great inconvenience to installation and maintenance. . The iron-lithium ion battery is suitable for high ambient temperature, the charging ambient temperature is 0℃~55℃, and the discharging ambient temperature is -20℃~60℃. It is suitable for outdoor stations with no machine room, no air conditioning, and ambient temperature above zero. ⑤Long life: The cycle life of lead-acid batteries is about 300 times, the highest is 500 times, the cycle life of lithium iron phosphate batteries is more than 2000 times, and the standard charging (5 hour rate) can reach 2000 times. Lead-acid batteries of the same quality will take 1 to 1.5 years, while lithium iron phosphate batteries will reach 7-8 years when used under the same conditions. Comprehensive consideration, the performance-price ratio will be more than 4 times that of lead-acid batteries. The future development trend of lithium iron phosphate batteries At present, lithium iron phosphate batteries are widely used in various fields such as hybrid vehicles, electric tools, electric bicycles, electric bicycles, power generation and energy storage devices. The emergence of lithium iron phosphate batteries is a major breakthrough in lithium-ion battery materials and has become a hot spot in competition research in various countries. At present, lithium iron phosphate products are in the embryonic stage of the industry, and my country’s environmental problems are prominent and energy problems are tense. Therefore, the lithium iron phosphate battery industry has a good development prospect. In the future, lithium iron phosphate batteries will become the mainstream of power lithium batteries. Looking at the world, the bottleneck of the current development of lithium iron phosphate batteries is the industrialization of the lithium iron phosphate material itself, which is the positive electrode active material. Therefore, research institutes and universities from all walks of life around the world pay very much attention to lithium iron phosphate materials, but there are not many companies that truly realize batch processing. Technological progress will become one of the most important development trends in the lithium iron phosphate battery industry. In the past few years, lithium iron phosphate has been severely squeezed by the ternary in the power field, and as subsidies have gradually declined, the marginal impact of subsidies on the market for new energy vehicles and power lithium batteries has weakened, safety, cost, cycle times, and stability Waiting becomes more important. At this stage, lithium iron phosphate has cost advantages, and there is room for survival in a cost-sensitive market. New technologies and methods are added to improve performance. The rebound of lithium iron phosphate in the passenger car market is a major trend. The future demand for lithium iron phosphate industry chain It is expected to pick up, and the supply and demand pattern will be improved. With the continuous improvement of technology, the future market demand for lithium iron phosphate products in commercial vehicles, passenger vehicles, energy storage and other fields will be broad. In particular, the new energy subsidy policy has gradually declined. Due to its obvious advantages in safety, service life and cost, lithium iron phosphate is expected to further increase in future demand. Comprehensive considerations, lithium iron phosphate batteries are most suitable for the future development direction of electric vehicle batteries.
