Any electronic product that provides energy with "electricity" has the core power storage components. Our common mobile phones, laptops, electric cars, etc. all rely on batteries to provide energy to provide services to people. Since batteries are so important, they have also made great breakthroughs in battery technology in recent years.
Take our electric vehicles that are most dependent on batteries. One hundred years ago, there were lead-acid battery electric vehicles. With the popularity of electric vehicles in recent years, relevant scientific researchers have never stopped updating battery technology. The batteries used now include: " lead-acid batteries, lithium batteries, nickel-hydrogen batteries, zinc-air batteries, graphene batteries", etc., and the most widely used in electric vehicles are lead-acid batteries and lithium batteries.
, especially lead-acid batteries. my country is the largest producer of lead-acid batteries in the world and the largest production and sales market for lead-acid battery electric vehicles. As a rising star, lithium batteries have also performed very well in recent years. Especially since lithium batteries have been used to electric vehicles, they have been interpreted as a substitute for lead-acid batteries. However, this is not the case. So, it is said that lithium batteries are better. Why are lead-acid electric vehicles more popular? You will understand the difference. What is better about
lithium battery than lead-acid battery?
Everyone says that lithium batteries are better than lead-acid batteries. As a rising star, there must be something better than the former, otherwise there is no need to be used. So, what is better for lithium batteries than lead-acid batteries? There are probably these points;
is the first difference in durability . The biggest disadvantage of electric vehicle batteries is that they are not durable enough. The reason why lithium batteries can become a rising star is that they have changed the durability of lead-acid batteries. The number of charges and discharges of lead-acid batteries is about 350 times, while the number of charges and discharges of lithium batteries is about 500 to 1,000 times. In theory, the life of lithium batteries is twice to 3 times that of lead-acid batteries.
followed by the difference between lightweight . Electric vehicles must be limited to less than 55 kg due to the requirements of the new national standard, if they want to meet the new national standard electric bicycle, they must be limited to less than 55 kg. This also gives a great opportunity for lighter lithium batteries. Because the internal structure of lithium batteries is different from lead-acid batteries. For a battery of the same capacity, the volume of lithium batteries is only one-third of the lead-acid batteries, and the weight is only two-fifths of the lead-acid batteries.
finally has the difference in battery life . Battery life is very important for electric cars. When we buy electric cars, generally lithium batteries are equipped with high-range electric cars. For example, many electric cars now have a battery life of more than 100 kilometers, and they are basically lithium-battery electric cars.
lead-acid battery electric vehicles are still the mainstream in the market
We have seen above that lithium batteries have three advantages over lead-acid batteries, and in terms of battery life and durability, these are the most concerned points of electric vehicles. This is no wonder many people think that lithium battery electric vehicles will be better than lead-acid battery electric vehicles, and even think that lithium batteries will replace lead-acid batteries.
However, from the current market perspective, the use of lead-acid batteries in two-wheeled electric vehicles is actually the mainstream. Conservatively estimated that at least 70% of electric vehicles use lead-acid batteries, while lithium batteries are more used on four-wheeled electric vehicles . For example, low-speed electric vehicles has regulations and requirements that lead-acid batteries are prohibited and lithium batteries must be used.What is the difference between
lithium batteries and lead-acid batteries?
So, lithium batteries have so many advantages, why are they not popularized in two-wheeled electric vehicles, or why are they not favored by consumers? What is the difference between lithium batteries and lead-acid batteries? There are about 2 points below;
01 lithium battery price is not affordable enough . Although lithium batteries are stronger than lead-acid batteries in terms of life and battery life, for economical and affordable vehicles like electric vehicles, the price is the "kingdom". The price of lithium batteries is several times that of lead-acid batteries, and there is no recycling value after scrapping. Even if the lead-acid batteries are scrapped, the recycling price is one-third of the purchase price. Therefore, the cost-effectiveness of lead-acid batteries is very high, which is incomparable to lithium-battery electric vehicles.
02 lithium battery is not as safe as lead-acid battery . The vehicles are still concerned about safety, especially in recent times, the electric car elevators are frequent in the electric car room, and the electric car has been in full swing. The electric cars of these incidents are all lithium batteries. Due to different technologies, the electrolyte inside the lithium battery has high flammability. Therefore, in terms of safety, lithium batteries are not as good as lead-acid batteries with mature technology.
Small experts suggest : After reading the above content, you must have your own understanding of why lithium batteries are not as popular as lead-acid battery electric vehicles. Even so, small experts believe that when purchasing, you may not only choose lead-acid battery electric vehicles. Excluding lithium battery electric vehicles, if the budget is sufficient and the commuting mileage is relatively long, then lithium batteries are actually the first choice. Of course, if you want to choose a low-priced and affordable electric vehicle, then lead-acid battery is still the first choice. You can choose an electric vehicle that suits you according to your actual needs. What would you choose to choose between
lead-acid battery and lithium battery? Everyone is welcome to comment and exchange, follow the small electric vehicle experts, and share information and opinions related to electric vehicles every day.
