Solar street lights use solar energy and are characterized by energy saving, environmental protection, convenient installation, and automatic control and maintenance, making them widely used in rural road lighting projects. Nowadays, solar street lights have been popularized in rural areas. Everyone knows that
solar street light batteries
are divided into lead-acid batteries and lithium batteries. The lithium batteries for solar street lights are further divided into ternary lithium batteries and lithium iron phosphate batteries.
Let’s first discuss the performance advantages and disadvantages of ternary lithium batteries. Advantages: their performance is less affected by temperature, they are suitable for low-temperature environments, and can operate in temperatures ranging from -15 degrees to 30 degrees. Disadvantages: the number of cycles is relatively short, and their lifespan is shorter compared to lithium iron phosphate batteries. Additionally, they have lower safety and stability, decompose easily at high temperatures, and can ignite combustible electrolytes and carbon materials in the battery, leading to explosive phenomena.
Now let’s look at the performance advantages and disadvantages of lithium iron phosphate batteries. Advantages: they have excellent charge and discharge performance, a higher number of cycles, longer lifespan, and better high-temperature stability, decomposing only at 700-800℃. Moreover, in situations of impact, puncture, or short circuit, they do not release oxygen molecules and do not cause violent combustion. Disadvantages: their performance is greatly affected by temperature, especially in low-temperature environments, where discharge capability and capacity significantly decrease, and they also have lower energy density.
At this point, both ternary lithium and lithium iron phosphate batteries have their own advantages and disadvantages, making it difficult to conclude which
solar street light lithium battery
has a greater advantage. So far, there has been no clear winner between them; ternary lithium batteries have a slight edge, but neither of them is an ideal solution at this stage. Solar street light manufacturers recommend using ternary lithium batteries in northern regions due to their superior low-temperature performance. In southern regions, however, using lithium iron phosphate batteries for solar street lights is more cost-effective.
