What are the advantages and disadvantages of lead-acid batteries and lithium batteries for electric vehicles?

There are three types of batteries generally used in electric bicycles, storage batteries, nickel-metal hydride batteries, and lithium batteries. Lithium battery electric bicycles are very light and agile, and use electricity for a long time. What are the advantages and disadvantages compared with batteries? 1. Half of the price of an electric bicycle is on the battery. The price of lithium batteries is much higher than that of lead-acid batteries. A lot more expensive. 2. In terms of quality, it has long endurance and can run farther than lead-acid batteries. 3. Be sure to pay attention to waterproofing during use, which is more difficult to service than lead-acid batteries. The manganese dioxide in the positive electrode of a lithium battery can generate heat with only a small drop of water. After the sulfur chloride in the lithium battery comes into contact with water, it generates hydrochloric acid and sulfur dioxide and releases heat at the same time. Several factors make the lithium battery a kind of fire in life. When using the lithium battery, we must pay attention to waterproof and moisture proof. 4. I personally think that although there are already lithium batteries on sale, the sales are not very satisfactory and are not recognized by the public. From an environmental perspective, lithium batteries are more environmentally friendly than lead acid. 5. Lead-acid batteries can now be repaired, including instruments plus manual repairs. I don't know if lithium batteries can be repaired. Lithium batteries are better. Lithium batteries are more than 3 times higher than lead-acid batteries in terms of volume ratio energy or weight ratio energy. Lithium batteries are smaller and lighter. Long cycle life. The key to running far is the battery capacity. It is meaningless to say who is far away alone. For example, they are both 48V20AH. Lithium batteries and lead-acid batteries are basically the same, because the capacity is the same, but the lithium batteries are lighter, so they can be slightly farther than lead-acid batteries. But if the lithium battery is 48V10AH and the lead acid is 48V20AH, then lead acid is definitely far away, needless to say. To put it simply, whoever has a larger capacity will run far. The advantage of lithium batteries is that they are lighter than lead-acid batteries and can be discharged at high currents. Others are the same.
