What are the ten advantages of lithium ion batteries?

　　(1) Long cycle life: the charging and discharging rate of lithium ion battery is 1C, and the cycle life is no less than 500 times. The capacitance at the 500th time is greater than 70% of the nominal copper beam. Even if the lead-acid battery is discharged at 0.5 and charged at 0.15 C, its cycle life is less than or equal to 350 times, and its capacitance is less than or equal to 60%

　　(2) Good low-temperature discharge performance: lithium ion battery can work normally at - 25 ℃, and its capacitance can reach 70% of the nominal capacity, while lead-acid battery can not work normally at - 25 ℃, and it is 50% of the capacitance at - 10 ℃

　　(3) Strong charge retention capacity: after two months of storage, the electrical capacity of fully charged lithium ion battery pack is greater than or equal to 80%, while that of lead-acid battery is only 40% - 50% of the nominal capacity

　　(4) Strong continuity ability. As the weight of the lithium-ion battery pack is only 30% of that of the lead-acid battery pack, the lithium-ion battery pack has a strong endurance under the same voltage and capacitance

　　(5) High specific energy: since the volume of lithium ion battery is only 30% of that of lead acid battery, the energy storage of lithium ion battery is greater than that of lead acid battery when using the same space

　　(6) Wide operating temperature range: lithium-ion battery can work in the range of - 25 ℃ to 55 ℃, while lead-acid battery can only work in the range of 10 ℃ to 40 ℃

　　(7) Short charging time: due to the high current charging characteristics of lithium ion batteries, the charging time is only 4-5 hours, while that of lead-acid batteries is 8-10 hours

　　(8) High green environmental protection performance: Compared with lead-acid batteries with a large amount of heavy metal lead harmful to human health and the environment, lithium ion batteries are high environmental protection products

　　(9) High current discharge: the lithium ion battery can discharge at a rate of 1C, and its capacity is only 60% of the rated capacitance

　　(10) High current discharge does not affect the cycle life: High current discharge at a rate of 1.5C has no effect on the cycle life of lithium ion batteries. Lead acid battery discharges at a rate of 1.5C under high current. Its cycle life is only 30% - 40% of the nominal cycle life.
