There are three major types of solar cells in solar street lamps, namely lithium batteries, lead-acid batteries and colloidal batteries. Among them, lithium batteries are increasingly favored by the solar industry because of their higher service life.
First, the energy storage is high, because the lithium ion is used, which is more stable than the solution, so the energy is more than 7 times that of other batteries.
Second, the use of long time, the use of more energy, the natural life is longer.
Third, small size and light weight, change the image of the past heavy, palm size, more convenient.
Fourth, the use of no water consumption, compared to lead acid, gel batteries, no aqueous solution, no waste of resources.
Fifth, the environment is more adaptable.
Up to 50 degrees high temperature, down to minus 20 degrees, can be used normally.
Sixth, to ensure the lighting of the night.
