Will lithium batteries replace lead-acid batteries?

Almost all batteries in cars are lead-acid batteries, while mobile phone batteries are basically lithium batteries, even more 3C products, such as tablet computers, etc., use lithium batteries, so can lithium batteries be widely used? Make it bigger for him, and then apply it to the car? The answer is no. If it is a little bit possible, some auto manufacturers will try it, but almost no auto manufacturer has tried to replace lead-acid batteries with lithium batteries. There are several reasons. First of all, because of the cost, the cost of lead-acid batteries is much lower than that of lithium batteries, whether it is electrode materials, electrolyte or assembly environment. The electrode materials of lead-acid batteries are lead oxide and lead sulfate, and the preparation process is simple. The cost is very low; however, the preparation of electrode materials for lithium batteries is much more complicated and expensive. In addition, the reason why we use lithium batteries for mobile phones is actually because lithium batteries have a higher energy density. To put it bluntly, while ensuring large capacity, the volume can be made as small as possible. But if the car uses lithium batteries, it is only because of the energy density of lithium batteries, which can save more space. However, for cars, saving space is not an important requirement, and after changing to lithium batteries, the entire power supply and electricity system must be changed. Then in order to save the weak demand of space, it is not worth changing the circuit parts and equipment of the whole car. ? It doesn't seem necessary. Of course, this is not the most important factor for cars not using lithium batteries. Lithium batteries also have two fatal weaknesses. The first is that the low-temperature performance of lithium batteries is worse than that of lead-acid batteries. Think about our mobile phones sometimes when it is a few degrees below zero, it is difficult to turn on, but sometimes the mobile phone cannot be turned on and it will not bring any danger; but the car is sports and safety-related, and it must be guaranteed to be in a harsh environment , It can start smoothly at low temperature; the safety of lead-acid batteries is very high in the current battery system. First of all, the excellent high-current performance means that the battery is not prone to accidents; even if an accident occurs, the positive and negative materials are all Lead compounds, while the electrolyte is still a sulfuric acid solution, none of the three are flammable.
