Should electric vehicles choose lead-acid batteries or lithium-ion batteries?

Traditional lead-acid batteries are relatively large in size, and the weight of the vehicle is relatively heavier. Li-ion batteries are not only small in size, but also relatively lightweight. Therefore, lithium-ion batteries have more advantages in lightness than lead-acid batteries. Lifetime The number of full charge and discharge times of lithium ion batteries can generally reach 500 times, while the number of full charge and discharge times for lead-acid batteries is only about 350 times, which means that the service life of lithium-ion batteries is about 1.5 times that of lead-acid batteries, which shows that lithium-ion batteries Battery electric vehicles have a longer service life than lead-acid battery electric vehicles. Battery price The price of lithium-ion batteries is higher than that of lead-acid batteries. Therefore, the price of lead-acid electric vehicles using batteries of the same size is much lower than that of lithium-ion electric vehicles. From this point of view, lead-acid battery electric vehicles have more advantages. Stability From this point of view, lead-acid electric vehicles are also more advantageous. Because compared with lithium-ion batteries, lead-acid battery technology is relatively mature, and it is also more stable, which means that lead-acid electric vehicles will have better safety. After-sales cost is well known, electric car batteries have a certain service life, so they must be replaced within a certain period of time. The price of lead-acid batteries is much lower than that of lithium-ion batteries, and the replacement price will also be lower than that of lithium-ion batteries. From this point of view, lead-acid electric vehicles also have more advantages. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
