What are the advantages of lithium batteries for electric vehicles compared to lead-acid batteries?

Lead-acid batteries are also called lead-acid batteries. Since the lead-acid battery was invented, it has become the world's largest production and most widely used battery due to its low price, easy availability of raw materials, reliable performance, easy recycling and suitability for high-current discharge. After more than one hundred years of development, lead-acid batteries have been continuously updated in technology and are now widely used in various fields such as automobiles, communications, electric power, railways, and electric vehicles. Lithium battery has large specific energy, high specific power, small self-discharge; no memory effect, good cycle characteristics, fast discharge, high efficiency, wide operating temperature range, no environmental pollution, is currently the highest specific energy battery, small size , Lightweight. Lithium batteries are also the research and development direction of various electric vehicle companies. The latest electric vehicles are basically equipped with lithium batteries or have high-end versions of lithium batteries. 1. Lithium batteries are much smaller and lighter in weight relative to general lead-acid batteries. Generally, a lithium battery of the same model is only half the size of a battery, and its weight is one third of that of a battery. The energy density of current lithium batteries is generally 200~260wh/g, and lead acid is generally 50~70wh/g. Then the weight energy density of lithium batteries is 3~5 times that of lead acid, which means that under the same capacity, lead The weight of acid batteries is 3 to 5 times that of lithium batteries, so lithium batteries occupy an absolute advantage in lightening energy storage devices. 2. The lifespan of lithium batteries is generally about 5 to 6 years, and the warranty period is generally about three years, which is much longer than the life of ordinary lead-acid batteries which only has one year or one and a half years. Batteries, and consumers’ use of lithium batteries is about one hundred yuan lower than the annual usage fee for batteries in general electric vehicles. 3. The lithium battery of the lithium battery electric vehicle is safer than the general lead-acid battery. There is a qualitative difference between the lithium battery and other general batteries; if the inferior quality lithium battery is selected, it will not happen when there is heavy pressure, impact, short circuit, etc. explosion. 4. Lithium batteries are more green and environmentally friendly in relation to general batteries, and have little environmental pollution. Because of their long service life, they can guard against environmental pollution caused by general battery replacement. 5. Because of the small size and low weight of lithium battery electric vehicles, they are generally light and beautiful, easy to move, and many lithium battery electric vehicles can also be folded. 6. When consumers are charging ordinary lead-acid battery electric vehicles, they have always worried about the memory effect of the battery. When the lithium battery is used, everyone can breathe a sigh of relief. The lithium battery does not have the memory effect. Advantages of lead-acid batteries 1. Hardness: The lead-acid boss has always adhered to the principle of the nine-sun magic power of the lead-acid boss that he is strong and he is strong. Allow you to be beaten and beaten, and you can continue to use it with a little patch. It is indeed very good to feed. 2. Inexpensive: The lead-acid boss has always been able to take the lead in electric vehicle batteries. This reason cannot be ignored at all. The price is only about one-third of that of lithium batteries. 3. Recyclable and reversible repair: The skill of the lead-acid boss is a must-have. After it is worn out, you can go to the electric car shop to make up the difference and trade in the old, which can minimize the loss. For the user, it is not a big deal. welfare.
