In this work, an empirical equation characterizing the battery's electrical behavior is coupled with a lumped thermal model to analyze the electrical and thermal behavior of the 18650 Lithium Iron Phosphate cell. Under constant current discharging mode, the cell temperature increases with increasing charge/discharge rates.
Since its first introduction by Goodenough and co-workers, lithium iron phosphate (LiFePO 4, LFP) became one of the most relevant cathode materials for Li-ion batteries and is also a promising candidate for future all solid-state lithium metal batteries.
Therefore, the lithium iron phosphate battery's volume is more significant while providing the same energy, making lithium iron phosphate batteries take up more space than ternary lithium batteries.
In addition, a three-dimensional heat dissipation model is established for a lithium iron phosphate battery, and the heat generation model is coupled with the three-dimensional model to analyze the internal temperature field and temperature rise characteristics of a lithium iron battery.
The anode of a lithium battery is usually a graphite carbon electrode, and the cathode is made of LiNiO2, LiMn2O4, LiCoO2, LiFePo4, and other materials . Researchers have extensively studied Lithium iron phosphate because of its rich resources, low toxicity, high stability, and low cost.
Lithium iron phosphate batteries will not release oxygen molecules when faced with impacts, needle sticks, short circuits. It will not burn even if it is damaged. In contrast, ternary lithium batteries have lower safety. The cathode of a lithium iron phosphate battery will only undergo internal decomposition at 700 to 800 degrees Celsius.
