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 .
In the charging process, the positive ions of a lithium iron phosphate battery go through the polymer diaphragm and transfer to the negative surface. In the discharging process, the negative ions go through the diaphragm and transfer to the positive surface.
For this purpose, the paper built a model of battery performance degradation based on charge–discharge characteristics of lithium iron phosphate batteries . The model was applied successfully to predict the residual service life of a hybrid electrical bus.
From Fig. 6, we can see that the positive surface of the failed lithium battery has a layer of white, irregular material called positive oxide. In the charging process, the positive ions of a lithium iron phosphate battery go through the polymer diaphragm and transfer to the negative surface.
The impact of lithium iron phosphate positive electrode material on battery performance is mainly reflected in cycle life, energy density, power density and low temperature characteristics. 1. Cycle life The stability and loss rate of positive electrode materials directly affect the cycle life of lithium batteries.
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 , .
