What are the advantages and applications of lithium batteries?

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 continuity capability. Since the weight of the lithium battery pack is only 30% of the lead-acid battery, under the same voltage and capacity, the continuation capability of the lithium battery is strong. 5. High specific energy: Since the volume of lithium battery is only 30% of lead-acid battery, the energy reserve of lithium battery is larger than that of lead-acid battery when using the same space. 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. 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 power 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. Application of electric vehicles For our country, automobile pollution is becoming more and more serious. Exhaust gas, noise and other environmental damages must be controlled and managed, especially in densely populated and traffic congested large and medium-sized cities. serious. Therefore, the new generation of lithium 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 batteries is another good strategy to solve the current situation.
