How does a lithium iron phosphate battery work?
A lithium iron phosphate (LiFePO4) battery functions by storing electrical energy in chemical form. During charging, lithium ions move from the positive electrode to the negative electrode through an electrolyte. When discharging, these ions return to the positive electrode, generating electricity that powers connected devices.Chart: Charging and Discharging Process
| Process | Description |
|---|---|
| Charging | Lithium ions migrate to the negative electrode |
| Discharging | Ions return to the positive electrode, generating current |
What advantages does LiFePO4 technology offer?
Lithium iron phosphate batteries provide several advantages:
- Safety: They are more stable than other lithium chemistries, reducing risks associated with thermal runaway.
- Durability: With a longer cycle life compared to lead-acid batteries, they offer better long-term value.
- Efficiency: High charge/discharge efficiency minimizes energy loss during operation.
- Environmental Impact: They are lead-free and designed with sustainable materials.
