Why are more and more solar street lights using lithium batteries?

Date:Mar 24, 2020

With the in-depth development of the new socialist countryside and the construction of a beautiful countryside, solar street lights have been used everywhere as the preferred lighting equipment. Solar street lights not only save energy and protect the environment but also do not generate electricity costs, so they are welcomed by the broad masses of the people. In the past, many solar street lights used lead-acid batteries, but nowadays, lithium batteries are basically used.


Why are lithium batteries so popular? What are the advantages of lithium batteries over lead-acid batteries?


1. Lithium battery is small in size, light in weight, and easy to transport. Compared with the lithium-ion energy storage system and lead-acid gel battery used in solar street lights, the weight is about one-third and the volume is about one-third. As a result, transportation is easier, and transportation costs naturally fall.


2. Lithium battery has high energy density and longer service life. Energy density refers to the amount of energy stored in a certain unit of space or mass. The greater the energy density of a battery, the more electricity stored in a unit weight or volume. There are many factors that affect the service life of lithium batteries, and energy density is one of the very important internal factors.


3. Solar street lights using lithium batteries are easy to install. When installing traditional solar street lights, a battery pit needs to be reserved, and the battery is placed in a buried box to seal it. The installation of lithium-ion solar street lights is much more convenient. You can directly install the lithium battery on the bracket, using a hanging type or a built-in type.


4. Lithium battery solar street light is easy to maintain. Lithium-ion solar street lights only need to take out the battery from the light pole or battery panel during maintenance, while traditional solar street lights need to dig out buried batteries during maintenance, which is more troublesome than lithium-ion solar street lights.
