LiFePo4
LiFePO₄ battery& nbsp;(short for Lithium Iron Phosphate battery) is a type of& nbsp;rechargeable lithium-ion battery known for its& nbsp;excellent safety, long lifespan, and thermal stability.
🔬 What it’s made of:
- Cathode: Lithium Iron Phosphate (LiFePO₄)
- Anode: Typically graphite (carbon)
- Electrolyte: Lithium salt in organic solvent
🔋 Key Features of LiFePO₄ Batteries:
| Feature | Description |
|---|---|
| Safety | Extremely stable and resistant to overheating or catching fire (much safer than other lithium chemistries) |
| Cycle Life | Can last 2,000 to 5,000+ full charge cycles — often 10+ years with proper care |
| Energy Density | Lower than other lithium-ion types (like NMC or NCA), but still efficient |
| Thermal Stability | Performs well in high temperatures, but charging in freezing temps can damage it |
| Weight | Lighter than lead-acid, but heavier than some high-energy lithium chemistries |
| Maintenance | Maintenance-free — no need for water top-ups or venting gases like lead-acid batteries |
| Environmental Impact | Uses non-toxic, abundant materials (no cobalt), and is more eco-friendly than other lithium types |
