Lithium iron phosphate batteries are a type of rechargeable battery made with lithium-iron-phosphate cathodes. Since the full name is a bit of a mouthful, they''re commonly abbreviated to LFP batteries (the "F" is from its scientific name: Lithium ferrophosphate) or LiFePO4. They''re a particular type of lithium-ion batteries

Introduction
Liu et al. investigated the effects of two different triggering methods, overheating and overcharging, on the TR of lithium iron phosphate batteries. Their findings demonstrated that under overcharge conditions, battery combustion is more severe, leading to higher fire risks.
In this paper, lithium iron phosphate (LiFePO4) batteries were subjected to long-term (i.e., 27–43 months) calendar aging under consideration of three stress factors (i.e., time, temperature and state-of-charge (SOC) level) impact.
With widespread applications for lithium-ion batteries in energy storage systems, the performance degradation of the battery attracts more and more attention. Understanding the battery’s long-term aging characteristics is essential for the extension of the service lifetime of the battery and the safe operation of the system.
They found that as the charging rate increases, the growth rate of lithium dendrites also accelerates, leading to microshort circuits and subsequently increasing the TR occurrence of lithium iron phosphate batteries.
