Explain the ten advantages of lithium-ion batteries for electric vehicles

Ten advantages of lithium-ion batteries for electric vehicles. Electric vehicle batteries are divided into lead-acid batteries and lithium-ion batteries. Compared with lead-acid batteries for electric vehicles, we know less about lithium-ion batteries. Let’s briefly introduce the ten advantages of lithium-ion batteries. Great advantage. 1 Long cycle life: Li-ion battery charge and discharge rate is 1C. Its cycle life is greater than or equal to 500 times. The capacitance at the 500th time exceeded 70% of the nominal copper beam. However, even if an ordinary 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 its capacitance is less than or equal to 60%. 2 Good low-temperature discharge performance: Li-ion batteries can work normally at -25°C, and their capacity can reach 70% of the standard capacity, while ordinary lead-acid batteries have a capacity of 50% at -10°C and at -25°C. Can't: Can work normally. 3. High battery retention capacity: After two months of storage, the capacity of a fully charged lithium-ion battery pack reaches or exceeds 80%. A normal lead-acid battery can only reach 40-50% of the rated capacity after two months of use. 4 Strong battery life: The weight of lithium-ion batteries is only 30% of ordinary lead-acid batteries, so under the same voltage and capacity, the battery life is strong. 5 Higher energy than ordinary lead-acid batteries: Since lithium-ion batteries are only 30% larger than ordinary lead-acid batteries, when using the same space, lithium-ion batteries have higher energy reserves than ordinary lead-acid batteries. 6 Wide operating temperature range: Li-ion batteries can work in the range of -25-55 degrees, while lead-acid batteries can work in the range of 10-40 degrees. On the other hand, ordinary lead-acid batteries can only work at a temperature of 10 to 40 degrees. 7 Short charging time: Li-ion batteries can be charged under high current, so the charging time is only 4-5 hours, while the charging time of ordinary lead-acid batteries is 8-10 hours. 8 High environmental performance: Compared with ordinary lead-acid batteries, lithium-ion batteries are very environmentally friendly products. Lead-acid batteries contain a large amount of heavy metal lead that is harmful to the human body and the environment. 9 High current discharge: Li-ion battery can discharge high current at 1C, and its capacity is only 60% of the rated capacity. 10 high current discharge does not affect cycle life: Li-ion battery 1.5c doubler high current discharge does not affect cycle life. When ordinary lead-acid batteries are discharged at a large current of 1.5c, their cycle life is only 30%-40% of the nominal cycle life.
