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

With the further development of the construction of new socialist countryside and the construction of beautiful villages, solar street lamps have been seen everywhere as the first choice of lighting equipment. Solar street lights are not only energy-saving and environmentally friendly, but also do not generate electricity, so they are welcomed by the masses of people. In the past, many solar street lights used lead-acid batteries. Now, lithium batteries are widely used. Why are lithium batteries so popular? What are the advantages of lithium batteries compared with lead-acid batteries? 1. Lithium batteries are small in size, light in weight, and easy to transport. Compared with lead-acid gel batteries for lithium-ion energy storage systems and solar street lights, the weight is about one-third and the volume is about one-third. In this way, it is easier to transport, and transportation costs are reduced. 2. Lithium battery has high energy density and long service life. Energy density is the amount of energy stored in a unit of space or mass. The higher the energy density of the battery, the more energy can be stored per unit weight or volume. There are many factors that affect the life of lithium batteries, and energy density is one of the most important internal factors. 3. Solar street lights using lithium batteries are easy to install. Traditional solar street lights need to leave a battery pit for installation, and a buried box to seal the battery. The installation of lithium battery solar street lights is much more convenient, and the lithium battery can be directly installed on the bracket, which can be suspended or hidden. 4. Lithium battery solar street lights are easy to maintain. Lithium-ion solar street lights only need to take out the battery from the pole or battery panel, while traditional solar street lights have to dig out the buried batteries, which is much more troublesome than lithium-ion solar street lights.
