Which is better, lithium battery or lead-acid battery?

Is it better to use lithium batteries for electric vehicles or lead-acid batteries? Compared with lead-acid batteries, lithium batteries have a higher average voltage and higher energy density. In other words, batteries of the same size have more capacity. In addition, lithium batteries are relatively lightweight, easy to carry, and have a relatively long life. In addition, lithium batteries are more adaptable to high and low temperatures, are less affected by temperature, and are more environmentally friendly. Of course, lithium batteries also have three shortcomings. Their safety and stability are relatively poor. If they are not handled properly, they are prone to explosion risks. In addition, lithium batteries cannot be discharged at high currents, and processing requirements are high, and the cost is higher. Compared with lithium batteries, lead-acid batteries are relatively cheap and more acceptable to the public. In addition, the high-rate discharge performance of lead-acid batteries is better. The most important thing is that the recycling price of lead-acid batteries is higher than that of lithium batteries. However, lead-acid batteries also have their own shortcomings, such as heavy metals easily cause environmental pollution; compared with lithium batteries, lead-acid batteries have lower energy density; and their service life is not as good as lithium batteries. What should I pay attention to when charging lithium batteries for electric vehicles for the first time? 1. The charging time for the first car lithium battery charge, because the battery car battery has not been charged and discharged when it is not used when it is shipped from the factory. It is necessary to ensure the normal operation of the battery. Under normal circumstances, the charging time is about 5-6 hours, and the battery can be fully charged, and the subsequent use can be charged a little longer. 2. After the first charge, although it is not the first charge, but the second charge is also considered a new car charge. At this time, you can let the battery car's battery run out, and then charge it for a long time. This charge can be maintained for 8 -9 or even 10 hours, in order to let the battery car chemical reaction go through a complete cycle. 3. When the battery car is charged for the first time, the charger may generate heat very quickly and very high. Therefore, especially in summer, the charger should not be placed on objects that are easy to heat or burn, and it is best not to put it on the battery car. On the seat, prevent fire.
