Solar street lights as lighting equipment has been everywhere. Solar street lights are not only energy-saving and environmentally friendly but also do not produce electricity, so they are welcomed by the general public. In the past, many solar street lights use lead-acid batteries, but now, basically, they use lithium batteries.
Why is lithium battery so popular? Compared to lead-acid batteries, what are the advantages of lithium batteries?
In recent years, lithium solar street lights have developed rapidly, not only in the beautiful countryside road lighting widely used, but also because of the lithium battery energy storage density, light quality, small size appeared in a variety of environments such as homes, neighborhoods, scenic parks, the development of solar lights, solar all-in-one lights, lawn lights, buried spotlights, solar aviation lights and other kinds of led lighting products, why lithium batteries will have such a rapid The development of it? That is, why is the lithium battery better than the lead-acid battery?
Lithium batteries are very different from lead-acid batteries in terms of internal reaction and use.
Lithium battery energy storage process of internal electron movement is a physical change, so the battery life is long, while the lead-acid batteries are characterized by low requirements for the use of the environment, in some low-temperature environment can still be used, but due to its internal charging and discharging process is a chemical change, so the service life is shorter. However, it should also be noted that the lithium battery group due to its characteristics, the consistency of the monomer requirements are very high, a group of batteries, as long as a different from other batteries, then the effect of the whole group will decline, so the production process of solar street lights lithium battery sorting is a very important link, as the use of lithium batteries solar street light customers you pay attention to observe?
1. lithium batteries are small in size and light in weight, easy to transport. The same power solar street light used lithium storage system and lead-acid colloidal batteries compared to about one-third of the weight, about one-third of the volume. In this way, transportation is easier, and transportation costs are naturally reduced.
2. Li-ion battery has high energy density and longer service life. Energy density refers to the size of the energy stored in a certain unit of space or mass. The greater the energy density of the battery, the more power stored per 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. Traditional solar street light installation requires a battery pit to be set aside and sealed with a buried box to put the battery in. The installation of lithium solar street light is much more convenient, you can directly install the lithium battery on the bracket, using the hanging type or built-in type.
4. Lithium solar street lights are easy to maintain. Lithium solar street light in the maintenance only need to take out the battery from the pole or under the panel, while the traditional solar street light in the maintenance of the need to dig out the buried battery, and lithium solar street light compared to the trouble much.
