With the deepening of the construction of new socialist countryside and beautiful villages, solar streetlights have become ubiquitous as lighting equipment. Solar streetlights are not only energy-saving and environmentally friendly, but also do not incur electricity costs, thus gaining popularity among the general public. Previously, many solar streetlights used lead-acid batteries, but now, lithium batteries are almost universally used.
Why are lithium batteries so popular? What are the advantages of lithium batteries compared to lead-acid batteries?
In recent years, lithium-ion battery solar streetlights have developed rapidly. They are not only widely used in rural road lighting, but also, due to the high energy density, light weight, and small size of lithium batteries, have appeared in various environments such as homes, residential areas, scenic parks, and more. This has led to the development of various LED lighting products, including solar lights, integrated solar lights, lawn lights, in-ground spotlights, and more. Why has lithium-ion battery technology developed so rapidly? In other words, why are lithium-ion batteries better than lead-acid batteries?
Lithium batteries and lead-acid batteries differ greatly in their internal reactions and usage methods.
The energy storage process of lithium batteries involves the movement of electrons through a physical change, resulting in a long battery life. Lead-acid batteries, on the other hand, are less demanding in terms of environmental requirements and can still operate in some low-temperature environments. However, because their charging and discharging processes involve chemical changes, their lifespan is shorter. It's also important to note that lithium battery packs, due to their characteristics, have very high requirements for the consistency of individual cells. If even one cell in a pack differs from the others, the overall performance of the pack will decrease. Therefore, sorting during the production process of lithium batteries for solar streetlights is a crucial step. As a customer using lithium batteries in your solar streetlights, have you paid attention to this?
1. Lithium batteries are small in size and light in weight, making them easy to transport. Compared to lead-acid gel batteries, lithium battery energy storage systems used in solar streetlights of the same power are about one-third the weight and one-third the volume. This makes transportation easier and naturally reduces transportation costs.
2. Lithium-ion batteries have high energy density and longer lifespan. Energy density refers to the amount of energy stored in a given unit of space or mass. The higher the energy density of a battery, the more electricity it stores per unit weight or volume. Many factors affect the lifespan of lithium-ion batteries, and energy density is one of the most important internal factors.
3. Lithium-ion battery-powered solar streetlights are easy to install. Traditional solar streetlights require a pre-drilled pit for the battery, which is then placed in an underground box and sealed. Lithium-ion battery-powered solar streetlights are much easier to install; the lithium battery can be directly mounted on a bracket, using either a suspended or recessed design.
4. Lithium-ion solar streetlights are easy to maintain. When maintaining a lithium-ion solar streetlight, you only need to remove the battery from under the pole or solar panel. In contrast, traditional solar streetlights require digging out the battery buried underground, making maintenance much more complicated.
