Advantages and future development trends of lithium iron phosphate 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 throughout the production 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 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 that of lead-acid batteries, the conversion efficiency of charge-discharge electric energy of lithium-ion battery packs can be greater than 97 %, and the energy conversion efficiency of lead-acid battery charging and discharging 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 also be buried under frozen soil, which brings 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 a lead-acid battery is about 300 times, the highest is 500 times, the cycle life of a lithium iron phosphate battery is more than 2000 times, and the standard charge (5 hour rate) can reach 2000 times. The lead-acid battery of the same quality will only take 1 to 1.5 years, while the lithium iron phosphate battery will be used for 7-8 years 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 very few companies that have truly achieved mass production. 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, stability, etc. More important. At this stage, lithium iron phosphate has cost advantages, and there is room for survival in cost-sensitive markets. New technologies and methods are added to improve performance. It is a general trend for lithium iron phosphate to rebound in the passenger car market. The demand for lithium iron phosphate industry chain is expected to pick up in the future. The supply and demand pattern will be improved. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
