LiFePO4 batteries are a specific type of lithium-ion battery characterized by their use of lithium iron phosphate as the cathode material. This choice of material contributes to several advantageous properties: Safety: One of the most notable features of LiFePO4 batteries is their inherent thermal stability.
In this paper, an in-situ swelling analyzer (SWE) is used to compare the swelling thickness and swelling force of large capacity LiFePO4 cells. It is found that during the charging and discharging process, the swelling trend of force and thickness is the same, and it decreases when charging occurs in the range of 25% to 70% SOC.
When different constant pressures are applied to the LiFePO4 cell, the maximum expansion thickness of the LiFePO4 cell increases with increasing pressure. Figure 4.

Performance: LiFePO4 batteries maintain a stable voltage throughout their discharge cycle, ensuring consistent performance until nearly depleted. This reliability is crucial for applications that depend on a steady power supply. Part 2. What are the different series of LiFePO4 batteries?
Voltage: Typically around 3.2V per cell, allowing for various configurations to achieve higher voltages. Capacity Range: Usually between 1000mAh to 3000mAh, catering to both small and medium power requirements. Price: Generally affordable, starting at $10-$20, making them accessible for many consumers. 2. Prismatic LiFePO4 Cells
