• Very safe and secure technology (No Thermal Runaway)
• Very low toxicity for environment (use of iron, graphite and phosphate)
• Calendar life > 10 ans
• Cycle life : from 2000 to several thousand (see chart below)
• Operational temperature range :up to 70°C
• Very low internal resistance. Stability or even decline over the cycles.
• Constant power throughout the discharge range
• Ease of recycling

• Level of power in C-Rate
• Depth of Discharge (DOD)
• Operational environment : temperature, humidity, etc.

Below chart shows the estimated number of cycles for Lithium Iron Phosphate battery cells (LFP, LiFePO4) according to the discharge power and DOD figures. The test conditions are those of a laboratory (constant temperature of 25 ° C, constant charging power and discharge).

In standard environment, and for 1C cycles, we can get from the chart the below life cycle estimation for LFP :

2000 cycles at 100% DoD
3000 cycles at 80% DoD
8000 cycles at 55% DoD
It should be noted that following the number of completed cycle, the batteries still have a nominal capacity > 80% of the original capacity.
