A battery is a device that converts chemical energy into electrical energy. It achieves this through a process called an electrochemical reaction. A typical battery consists of three essential components: an anode (negative electrode), a cathode (positive electrode), and an electrolyte. The anode is typically made of a metal that readily gives up electrons, while the cathode is made of a material that readily accepts electrons. The electrolyte is a solution or paste that conducts ions between the anode and cathode.
When the battery is connected to a circuit, a chemical reaction occurs at the anode. This reaction causes the anode material to lose electrons, which flow through the external circuit to the cathode. Simultaneously, ions from the electrolyte migrate through the electrolyte to balance the charge. The electrons flowing through the external circuit create an electric current, which powers the device connected to the battery. The reaction at the cathode consumes the electrons, completing the circuit. The specific chemical reactions that occur depend on the materials used in the battery's construction. Different battery types employ different chemicals to generate different voltages and power outputs. For instance, alkaline batteries use zinc and manganese dioxide, while lithium-ion batteries utilize lithium compounds. The battery continues to produce electricity until one of the reactants is consumed. At this point, the battery is considered discharged.

LiFePO4 battery fires start from thermal runaway caused by overcharging, short circuits, over-discharging, defects, or external heat. This causes rapid heating, flammable gas release, and intense, fast-spreading fires.
Lithium iron phosphate (LiFePO4) batteries, while generally safer than other lithium-ion battery chemistries, can still catch fire under certain conditions. Fires initiate through a process called thermal runaway. This occurs when internal cell resistance increases, leading to increased heat generation. Several factors contribute to this: Overcharging: Pushing more energy into the battery than its design allows causes excessive heat and can initiate thermal runaway. Short circuits: An internal or external short circuit creates a low-resistance path for current flow, generating intense heat. This can rapidly heat the battery beyond its safe operating temperature. Over-discharging: Draining the battery completely can damage the internal components, leading to heat generation and potential thermal runaway. Manufacturing defects: Faulty cells or poor manufacturing processes can create internal weaknesses or inconsistencies that increase the risk of thermal runaway. External heat: Exposure to extreme temperatures (high heat from external sources) can directly contribute to the overheating of the battery and trigger the process. Once thermal runaway begins, the propagation of the fire is rapid. The high temperatures generated within the cell cause the electrolyte to decompose, releasing flammable gases. These gases can ignite, causing further heating and releasing even more gases in a positive feedback loop. The rapid heating and combustion of the flammable materials lead to a quickly spreading fire. The resulting flames can be intense and difficult to extinguish, particularly with larger battery packs.
