What are the advantages and disadvantages of lithium batteries and lead-acid batteries?

1. In terms of volume and weight: Lithium batteries are lighter than lead-acid batteries. Under normal circumstances, the capacity of lithium batteries with the same volume can reach 2 to 3 times that of lead-acid batteries. This is related to the concept of weight energy density. The current lithium battery energy density is generally 200~260wh/g, and lead acid is generally 50~70wh/g. Then the weight energy density lithium battery is 2-3 times that of lead acid. This means that with the same quality, lead-acid batteries are 2-3 times that of lithium batteries, so lithium batteries have an absolute advantage in lightening energy storage devices. 2. Volume: With the same capacity, the volume of lithium batteries is about 30% smaller than that of lead-acid batteries. Because the volume capacity density of lithium batteries is usually about 1.5 times that of lead-acid batteries. 3. Life cycle and battery life: The service life of lithium batteries is about 2-3 times that of lead-acid batteries. The current life of lead-acid batteries is 2 About a year or so, the cycle charge and discharge is generally within 300 times, while the lithium battery cycle charge and discharge more than 500 times, the general life span is more than 3 years, and lithium battery manufacturers have proposed a 3-year warranty. If the lithium battery is used reasonably, it is not subject to high temperature, and there is almost no major battery loss within three years. The storage capacity of the battery will drop a lot after one or two years. 4. Price: Lithium batteries are currently more expensive than lead-acid batteries, about 3 times more expensive, but combined with the decomposition of service life and the same cost, the life cycle of lithium batteries is still longer. 5. Safety and applicability: Because the safety of lithium batteries is slightly worse than that of lead-acid batteries, various safety prevention tasks must be done during use, such as guarding against external forces or accidents that may cause damage to lithium batteries, because this may cause Fire or explosion; Statement: Some pictures and content of articles published on this site are from the Internet.
