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 .
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.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
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 , .
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.
Part of the charge–discharge cycle curve of lithium iron battery. According to the testers record, ninety-six battery samples failed (when the battery capacity is less than 1100 mA h). The cycles are listed in Table 2 in increasing order, equivalent to the full life cycle test.
