Lithium ion batteries (LIBs) are considered as the most promising power sources for the portable electronics and also increasingly used in electric vehicles (EVs), hybrid electric vehicles (HEVs) and grids storage due to the properties of high specific density and long cycle life [1].However, the fire and explosion risks of LIBs are extremely high due to the energetic and
Currently, lithium iron phosphate (LFP) batteries and ternary lithium (NCM) batteries are widely preferred [24].Historically, the industry has generally held the belief that NCM batteries exhibit superior performance, whereas LFP batteries offer better safety and cost-effectiveness [25, 26].Zhao et al. [27] studied the TR behavior of NCM batteries and LFP batteries.

The explosions were initiated by activating thermal runaway in three commercial batteries: (1) lithium nickel manganese cobalt oxide (NMC), (2) lithiumiron phosphate (LFP), and (3) lithium titanate oxide (LTO). Post-explosion aerosols were collected on anodisc filters and analyzed by scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDS). The

The use of lithium-ion batteries, such as lifepo4 batteries, is becoming increasingly popular in consumer electronics and energy storage applications due to their high power density, long cycle life and low self-discharge rate. However, the potential for a battery explosion always exists when using these types of rechargeable cells.
Pushing a LiFePO4 battery beyond its designated limit can generate excessive heat, potentially triggering thermal runaway and leading to fire. A direct connection between the positive and negative terminals can cause an uncontrolled release of energy, creating dangerous heat and fire hazards.

The paper studied the gas production and flame behavior of the 280 Ah large capacity lithium iron phosphate battery under different SOC and analyzed the surface temperature, voltage, and mass loss of the battery during the process of thermal runaway comprehensively. The thermal runaway of the battery was caused by external heating.
However, the mainstream batteries for energy storage are 280 Ah lithium iron phosphate batteries, and there is still a lack of awareness of the hazard of TR behavior of the large-capacity lithium iron phosphate in terms of gas generation and flame.
Among the diverse battery landscape, Lithium Iron Phosphate (LiFePO4) batteries have earned a reputation for safety and stability. But even with their stellar track record, the question of potential fire hazards still demands exploration.
From the aspect of preparation of lithium iron phosphate battery, since the LiFePO4 nano-sized particles are small, the specific surface area is high, and the high specific surface area activated carbon has a strong gas such as moisture in the air due to the carbon coating process.
