A LiFePO₄ battery (Lithium Iron Phosphate) is a type of lithium-ion battery known for its safety, long lifespan, and thermal stability. It is commonly used in electric vehicles, solar energy storage, and backup power systems.
Key Features of LiFePO₄ Batteries
- Safety & Stability
- More stable than traditional lithium-ion batteries (e.g., LiCoO₂).
- Lower risk of thermal runaway (overheating or explosion).
- Can withstand higher temperatures.
- Long Cycle Life
- Can last 2,000–5,000 charge cycles, significantly more than Li-ion or lead-acid batteries.
- Can last 10+ years with proper use.
- High Discharge & Charge Efficiency
- Efficiency up to 95–98% (higher than lead-acid).
- Maintains steady voltage output.
- Lightweight & Compact
- Weighs less than lead-acid batteries while offering the same or better capacity.
- Eco-Friendly
- Non-toxic & recyclable, unlike some lithium-ion chemistries that contain cobalt.
Common Applications
- Electric Vehicles (EVs) & E-Bikes
- Solar Energy Storage Systems
- Backup Power (UPS, Telecom, Data Centers)
- Marine & RV Batteries
- Medical & Industrial Equipment
