Why can lithium batteries successfully replace lead-acid batteries?

The main battery used in electric vehicles is lead-acid batteries. Electric vehicles with lead-acid batteries as the main power do have great benefits in the process of use, which will greatly reduce the environmental pollution caused by fuel vehicles and fuel motorcycles. However, when using lead-acid batteries, there are also some problems, and the biggest problem is that abandoned lead-acid rechargeable batteries have serious environmental pollution, and its pollution can not be found by sense of smell and vision. According to the survey, some data show that due to the short service life of lead-acid batteries, it is generally about one year, which is easy to cause many abandoned lead-acid batteries. If these abandoned lead-acid batteries are not properly treated, the sulfuric acid and sulfuric acid in the abandoned lead-acid batteries will be destroyed. At the same time, due to mechanical wear and corrosion for a certain period of time, heavy metal lead and electrolyte sulfuric acid in lead-acid batteries leak out, and then enter the human food chain through various channels, which will also cause chronic poisoning in some organs of the human body. The state has issued relevant laws and regulations on the harm caused by lead-acid batteries, and at the same time, some electric vehicle manufacturers have begun to look for new batteries-"lithium batteries", which are the main substitute products for lead-acid batteries at present. This battery has a longer life, lighter weight, greater power and less pollution to the environment, and has become the primary substitute today. For this reason, many electric vehicle companies have developed a new type of electric vehicle according to the needs of consumers, and the "lithium battery electric vehicle" has also been loved by many consumers.
