What are the advantages of lithium-ion batteries compared to lead-acid batteries?

1. Lithium-ion batteries are much smaller and lighter in weight than ordinary batteries. Generally, a lithium-ion battery of the same model is only half the size of a lead-acid battery and weighs one-third of a battery. 2. The life of lithium-ion batteries is generally about 5 to 6 years, and the warranty period is generally about three years, which is much longer than that of lead-acid batteries, which only have a life of one year or one and a half years, so don’t worry about whether to replace it every year. battery. 3. Lithium-ion batteries Lithium-ion batteries in electric vehicles are safer than ordinary batteries. Lithium-ion batteries are qualitatively different from other ordinary batteries. They will not explode when subjected to heavy pressure, impact, short circuit, etc. 4. Lead-acid batteries related to lithium-ion batteries are greener and have little environmental pollution, because the long service life can prevent environmental pollution caused by lead-acid battery replacement. 5. Because of the small size and low weight of lithium-ion battery electric vehicles, they are generally light and beautiful, convenient to move, and many lithium-ion 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-ion battery is used, everyone can breathe a sigh of relief. The lithium-ion battery does not have the memory effect. 1. Weight energy density: the current lithium-ion battery energy density is generally 200~260wh/g, lead acid is generally 50~70wh/g, then the weight energy density lithium ion battery is 3~ of lead acid 5 times, which means that with the same capacity, lead-acid batteries are 3 to 5 times that of lithium-ion batteries, so lithium-ion batteries have an absolute advantage in lightening energy storage devices. 2. Volumetric energy density: The volumetric capacity density of lithium-ion batteries is usually about 1.5-2 times that of lead-acid batteries, so with the same capacity, the volume of lithium-ion batteries is about 30%-50% smaller than that of lead-acid batteries. 3. Life cycle: The cycle times of lithium ion batteries are more than 2000 times, and the cycle times of lead-acid batteries are usually around 300-350 times, so the service life of lithium-ion batteries is about 3-6 times that of lead-acid batteries. 4. Charging and maintenance: The power lithium-ion battery has a fast charging function. In the case of the same specification and capacity, the charging time of the lithium-ion battery is only 1/2 of the lead-acid battery. At the same time, the charging of lead-acid batteries is more complicated, because lead-acid batteries have a memory effect, and improper charging will cause the capacity of the battery to decrease; while lithium-ion batteries have no memory effect, so do not use special methods during charging and maintenance, do not worry Dissatisfied charging causes problems such as shrinking battery capacity. 5. Environmental protection: There is a large amount of lead in lead-acid batteries, which will pollute the environment if they are not handled properly after being discarded; while lithium-ion batteries are greener in production, have little environmental pollution, and can have a long service life. Prevent environmental pollution caused by ordinary battery replacement. Disclaimer: Some pictures and content of articles published on this site are from the Internet.
