For Solar LED Lights, Why Choose LiFePO4 Battery?

With rising concerns about the depletion of fossil fuels and an increase in greenhouse gases, today, solar LED lights are becoming more popular. The battery is a critical part of solar lights, we found LiFePO4 battery is the best option after testing Ni-MH and Lithium batteries.

Below are the advantages of LiFePO4 battery for your reference.

1. Improvement of safety performance

The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at a high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good properties, safety.

2. Improvement of lifespan

Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as the positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the cycle life of lithium iron phosphate power batteries can reach more than 2,000 times, and the standard charging (5 hours rate) can reach 2,000 times.

3. Good high temperature performance 

The electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃. Wide operating temperature range (-20℃-75℃), with high temperature resistance, the electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

4. Large capacity

No matter what state the battery is in, it can be used at any time, no need to discharge it before charging.

5. Light weight

The volume of the lithium iron phosphate battery with the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.

6. Environmental protection

Lithium iron phosphate batteries are generally considered to be free of any heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), non-polluting, in line with European RoHS regulations, and are absolutely green and environmentally friendly batteries certificate.
