Major advantages of Lithium Iron Phosphate:
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
Life-cycle ofLithium Iron Phosphate technology (LiFePO4)
Lithium Iron Phosphate technology is that which allows the greatest number of charge / discharge cycles. That is why this technology is mainly adopted in stationary energy storage systems (self-consumption, Off-Grid, UPS, etc.) for applications requiring long life.

The actual number of cycles that can be performed depends on several factors:
Quality of Lithium Cell
Level of power in C-Rate (1C rate means full discharge or charge in 1 hour, 2C is the same but in half an hour)
Depth of Discharge (DOD)
Operational environment : temperature, humidity, etc.
Below chart shows the estimated number of cycles for our 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 charge and discharge power ).
