Analysis of the reliability and failure mode of lithium iron phosphate batteries is essential to ensure the cells quality and safety of use. For this purpose, the paper built a model of battery performance degradation based on charge–discharge characteristics of lithium iron phosphate batteries .
Charge–discharge cycle life test Ninety-six 18650-type lithium iron phosphate batteries were put through the charge–discharge life cycle test, using a lithium iron battery life cycle tester with a rated capacity of 1450 mA h, 3.2 V nominal voltage, in accordance with industry rules.
At a room temperature of 25 °C, and with a charge–discharge current of 1 C and 100% DOD (Depth Of Discharge), the life cycle of tested lithium iron phosphate batteries can in practice achieve more than 2000 cycles , .
To investigate the cycle life capabilities of lithium iron phosphate based battery cells during fast charging, cycle life tests have been carried out at different constant charge current rates. The experimental analysis indicates that the cycle life of the battery degrades the more the charge current rate increases.
In this work, we develop data-driven models that accurately predict the cycle life of commercial lithium iron phosphate (LFP)/graphite cells using early-cycle data, with no prior knowledge of degradation mechanisms.
A lifetime model has been developed based on a static experimental analysis at various SoC conditions and temperatures . The developed model for lithium iron batteries is showing quite good results compared to experimental results but at low SoC levels the model is not accurate enough.
