LiFePO4 batteries, or lithium iron phosphate batteries, utilize lithium iron phosphate as their primary cathode material, offering enhanced safety, stability, and longevity compared to other lithium-ion technologies. Their unique chemical composition contributes significantly to their performance in various applications.
What is the chemical structure of LiFePO4 batteries?
LiFePO4 batteries consist mainly of lithium iron phosphate (LiFePO4) as the cathode material, which provides excellent thermal stability and safety characteristics. The anode typically comprises graphite, while a lithium salt electrolyte facilitates ion movement during charge and discharge cycles.

| Component | Formula | Function |
|---|---|---|
| Cathode Material | LiFePO4 | Stores lithium ions |
| Anode Material | C (Graphite) | Releases lithium ions |
| Electrolyte | LiPF6 | Conducts lithium ions |
| Separator | Polyethylene | Prevents short-circuiting |
How does lithium iron phosphate function in batteries?
During charging, lithium ions move from the cathode (LiFePO4) through the electrolyte to the anode (graphite). During discharge, this process reverses, allowing electrical energy to power devices.Chart Title: Charge/Discharge Cycle
| Phase | Process |
|---|---|
| Charging | Lithium ions move to anode |
| Discharging | Lithium ions move back to cathode |
