What are the advantages of lithium-ion batteries related to lead-acid batteries

Regarding lead-acid batteries, lithium-ion batteries have many advantages. Let’s briefly analyze the ten advantages of lithium-ion batteries: 1. Long cycle life: Li-ion batteries are charged and discharged at a rate of 1C, and their cycle life is greater than or equal to 500 The electric capacity at the 500th time is 70% greater than the nominal copper beam. 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. Low temperature discharge performance is good: Li-ion batteries can work normally at -25 degrees. Its electric capacity can reach 70% of the nominal capacity, while the lead-acid battery has 50% of the capacity at -10°C, and it does not work normally at -25°C; 3. Strong charge retention capacity: fully charged Lithium-ion battery packs have a capacity greater than or equal to 80% after being placed for two months, while lead-acid batteries are only 40%-50% of the nominal capacity after being placed for two months; 4. The ability to continue running is strong, due to lithium ion The weight of the battery pack is only 30% of the lead-acid battery, so under the same voltage and capacity, the lithium-ion battery has a strong ability to continue; 5. High specific energy: because the volume of the lithium-ion battery is only that of a lead-acid battery 30%, so when using the same space, the energy reserve of lithium-ion batteries is larger than that of lead-acid batteries; 6. Wide operating temperature range: lithium-ion 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: Because lithium-ion batteries can be charged with large currents, the charging time is only 4-5 hours, while lead-acid batteries need 8 to 10 hours; 8. High green and environmental protection performance: Compared with lead-acid batteries with a large amount of heavy metal lead that is harmful to the human body and the environment, lithium-ion batteries are highly environmentally friendly products; 9. Large current discharge: Lithium-ion batteries are discharged at a high current at a rate of 1C. Its capacity is only 60% of the rated capacity; 10. High-current discharge does not affect cycle life: Li-ion batteries are discharged at a high current rate of 1.5C and have no effect on their cycle life. The lead-acid battery discharges at a high current rate at 1.5C. Its cycle life is only 30%-40% of the nominal cycle life.
