Why are many cars still using lead-acid batteries that are both heavy and have a low lifespan?

Lead-acid batteries used in cars are commonly known as batteries. When we mention them, a cumbersome image will appear in our minds. It is the big black block in the engine compartment. This takes up space and adds new cars. Heavy things are very not durable. Its important function is to start the engine and power off the car lights and in-car multimedia in a short time. The intensity of use is also very low, but even so, its lifespan is very short, generally It can only be used for 3-4 years. If it is well maintained, it may take about 5 years. Compared with the old lead-acid batteries, today's battery technology is more and more developed. Compared with the current common lithium-ion batteries As far as lead-acid batteries are concerned, lithium-ion batteries have a smaller volume, larger capacity, and longer lifespan, while mature lithium-ion batteries can already allow a pure electric vehicle to run five to six hundred kilometers. So the question is, lead-acid batteries are bulky and have a low lifespan. Why are many cars still in use? The reason is simple. First of all, although stable lithium-ion batteries are advanced, the biggest disadvantage is that they are not resistant to high and low temperatures, while lead-acid batteries are not. Lead-acid batteries can still start cars even at a low temperature of -50 degrees. In the case of ion batteries, the power of -15 degrees begins to decrease sharply. The second is safety. Everyone knows that the temperature of the car engine compartment is very high, especially for turbocharged models. If your battery is under such high-temperature working conditions for a long time, The potential safety hazard is great. Secondly, in the event of a collision, the starter battery is located on the head of the car. It is easily affected when the car collides. The lead-acid battery will not burn violently even in a collision. One big advantage is the economy. Lead-acid batteries are far lower than lithium-ion batteries in terms of electrode materials, electrolytes, and equipment and environmental requirements. However, with the advancement of temperature control technology, lithium-ion batteries will become more important in the future In a period of time, it is very likely to replace lead-acid batteries, it is only a matter of time
