What are the advantages of lithium batteries? What kind of applications does it have?

Advantages of lithium battery 1. Long cycle life: Lithium battery is charged and discharged at a rate of 1C, and its cycle life is greater than or equal to 500 times. The electric capacity at the 500th time is 70% greater than the nominal copper beam. And even if the lead-acid battery is discharged at 0.5 and charged at 0.15C, its cycle life is less than or equal to 350 times, and the capacity is less than or equal to 60%. 2. Good low-temperature discharge performance: Lithium batteries can work normally at -25 degrees, and their capacity can reach 70% of the nominal capacity, while lead-acid batteries have 50% of the capacity at -10 degrees, and at -25 degrees. No time: It can work normally. 3. Strong charge retention ability: after placing a fully charged lithium battery pack for two months, its capacity is greater than or equal to 80%, while lead-acid batteries are placed for two months, only 40%-50% of the nominal capacity . 4. Strong continuation ability. Because the weight of the lithium battery pack is only 30% of the lead-acid battery, under the same voltage and capacity, the continuation ability of the lithium battery is strong. 5. High specific energy: Since the volume of lithium batteries is only 30% of lead-acid batteries, the energy reserve of lithium batteries is larger than that of lead-acid batteries when the same space is used. 6. Wide operating temperature range: Lithium batteries can work in the range of -25 degrees to 55 degrees, while lead-acid batteries can only work in the range of 10 degrees to 40 degrees. 7. Short charging time: Lithium batteries have the characteristics of being able to be charged with large currents, so the charging time is only 4-5 hours, while the lead-acid battery takes 8 to 10 hours. 8. High environmental protection performance: Compared with lead-acid batteries which have a large amount of heavy metal lead which is harmful to the human body and the environment, lithium batteries are highly environmentally friendly products. 9. High current discharge: Lithium battery discharges at a high current at a rate of 1C, and its capacity is only 60% of the rated capacity. 10. High-current discharge does not affect cycle life: Lithium batteries are discharged at a high current at a rate of 1.5C and have no effect on their cycle life. The lead-acid battery discharges at a high current at a rate of 1.5C. Its cycle life is only 30%-40% of the nominal cycle life. Application of lithium batteries In recent years, the application range of lithium batteries has become more and more extensive. Lithium batteries are widely used in energy storage power systems such as water power, thermal power, wind power and solar power stations, as well as electric tools, electric bicycles, electric motorcycles, electric vehicles, Military equipment, aerospace and other fields. At present, lithium batteries have gradually expanded to the fields of electric bicycles and electric vehicles. Below we will specifically analyze several industries in which lithium batteries are used. 1. The application of electric vehicles At present, most of the electric vehicles in our country still use lead-acid batteries as power. The battery itself has a mass of more than ten kilograms. If a lithium battery is used, the weight of the battery is only about 3 kg. Therefore, the replacement of lead-acid batteries for electric bicycles with lithium batteries is an inevitable trend. In this way, the lightness, convenience, safety and cheapness of electric bicycles will be welcomed by more and more people. 2. The application of electric vehicles For our country, automobile pollution is becoming more and more serious. Exhaust gas, noise and other damage to the environment have to be controlled and managed, especially in some densely populated and traffic congested large and medium cities. serious. Therefore, a new generation of lithium batteries has been vigorously developed in the electric vehicle industry due to its pollution-free, low-polluting, and energy-diversified characteristics, so the application of lithium batteries is another good strategy to solve the current situation. 3. Aerospace applications Because of the strong advantages of lithium batteries, aerospace organizations also apply lithium batteries to space missions. At present, the important use of lithium batteries in the aviation field is to provide support for launch and in-flight calibration and ground operations; at the same time, it is beneficial to improve the efficiency of primary batteries and support night operations. Boeing is a leader in the use of advanced large-capacity and high-power lithium batteries. Its Boeing 787 installed lithium batteries as the main battery and auxiliary power unit batteries in 2011, becoming the world's first lithium battery to be used in aircraft critical systems. Technical civilian airliner. Disclaimer: Some pictures and content of articles published on this site are from the Internet. If there is any infringement, please contact to delete.
