The reason why more and more solar street lamps use lithium batteries

With the development of socialist road lighting, and the general development of new rural lighting. Solar street lamp is not only energy saving and environmental protection, but also will not produce electricity charges, so it is welcomed by the masses. In the past, many solar street lamps used lead-acid batteries, but now, they basically use lithium batteries.
Why are lithium batteries so popular? What are the advantages of lithium battery compared with lead acid battery?
Li ion battery is small in size, light in weight and easy to transport. Compared with the solar energy street lamp, the lead-acid gel battery and the lithium ion energy storage system have a weight of about 1/3 and a volume of about 1/3. In this way, the transportation is more convenient and the transportation cost is naturally reduced.
Lithium battery has high energy density and long service life. Energy density refers to the amount of energy stored in a certain space or mass unit. The higher the energy density of a battery, the more energy it can store per unit weight or volume. There are many factors affecting the service life of lithium batteries, among which energy density is one of the most important internal factors.
Three. Lithium battery solar street lamp is easy to install. The traditional solar street lamp installation should reserve the battery pit, and the battery should be sealed in the buried box. And the installation of lithium solar street lamp is more convenient, the lithium battery can be directly installed on the bracket, using hanging or hidden.
Lithium solar street lamp is easy to maintain. The maintenance of lithium solar street lamp only needs to remove the battery from the lamp pole or panel, while the traditional solar street lamp needs to dig out the buried battery, which is more troublesome than lithium solar street lamp.
