The battery is one of the key components of the led solar street light. led solar street light batteries are of various types, so which one is the most suitable for LED solar street lights?
Colloidal batteries
The colloidal battery is a new type of long-cycle life battery, which consists of lithium metal and electrolytes and can generate electricity through chemical reactions.
Advantages: Colloidal batteries have a long cycle life and a high discharge performance, which can ensure the continuous operation of equipment for a long time.
Can be used safely under various high and low-temperature conditions. Good shock resistance and suitable for long-distance transport. The number of deep cycles is about 500-800 times.
Disadvantages: higher cost, sometimes even more than the price of lithium electronic batteries.
Ternary lithium battery
The ternary lithium battery is a new type of long-cycle life battery, which consists of ternary materials and organic electrolytes, and can generate electricity through chemical reactions.
Advantages: Ternary lithium batteries are small in size, have higher capacity density, and have very good low-temperature resistance, making them ideal for use in low-temperature areas.
The number of deep cycles is about 300-500, and the life span is about one time longer than that of lead-acid batteries.
Disadvantages: The high-temperature properties are poor and its internal structure is unstable.
Lead-acid batteries
Lead-acid batteries are a common type of long-cycle battery, consisting of a solution of lead and acid that produces electricity through a chemical reaction.
Advantages: for the same capacity, lead-acid batteries are the cheapest of the four. The number of deep cycles is approximately 300-500.
Disadvantages: requires regular maintenance and inspection, cannot accept high-temperature environments, causes pollution to the environment, and has a short service life.
Lithium iron phosphate batteries
Lithium iron phosphate is a new type of long-cycle life battery, which consists of lithium iron phosphate material and organic electrolyte, which can generate electricity through chemical reactions.
Advantages: Lithium iron phosphate batteries have good stability and relatively stable electrochemical properties, which determines a stable charge and discharge platform.
As a result, the battery does not undergo structural changes during charging and discharging and will not burn or explode.
It is still safe under special conditions such as extrusion and needling. The number of deep cycle charges is around 1500-2000 times and the service life is long, generally up to 7-9 years.
Disadvantages: The price is the highest among the above 4 types of batteries under the same capacity.
Therefore, when configuring a solar street light, you need to choose a battery with the right capacity. Of all these batteries, lithium iron phosphate batteries offer the best value for money.
High performance, safety, and stability, and most importantly, a long service life. As long as the battery is well maintained and well used, the life of the led solar street light will naturally be extended.
