Why Lithium Iron Phosphate Batteries Rock!

Our Solarpod™ 240, 1K, and Polaris 5K use the amazing LiFePo4 Lithium Iron Phosphate battery technology. We’re quite happy with the great performance and incredible safety of LiFePo4. But there are so many different battery technologies and acronyms floating around that it can be confusing. We’re going to explain what LiFePo4 is and why we’re so enthusiastic about it.


Lithium Iron Phosphate is a natural mineral. Due to it’s color and crystalline nature it’s known as an Olivine. It was discovered in 1996 by the researchers at the University of Texas at Austin. The molecular formula for Lithium Iron Phosphate is LiFePo4, but it is also known as simply LFP.


Batteries that use LFP cathodes have great thermal and chemical stability. They provide a longer cycle life, a constant discharge voltage, and slower rate of capacity loss. What this means in plain English is that LFP batteries last longer and provide full power until drained.
Increased safety is also a major benefit of LFP batteries. Their great thermal and chemical stability ensure the batteries are structurally stable. LFP is also safer than manganese and cobalt avoiding financial and environmental costs. LFP has no known carcinogenicity. That means it’s not known to cause cancer.


With those kinds of benefits LFP was a natural choice for Solarpod™ by Sunbird Solar. Longer life, constant discharge, better for the environment, and better for you.
Next up we’re going to discuss the difference between mono-crystalline and poly-crystalline solar panels.
