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.
The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.
As we all know, lithium iron phosphate (LFP) batteries are the mainstream choice for BESS because of their good thermal stability and high electrochemical performance, and are currently being promoted on a large scale .
