Are lithium iron phosphate (LFP) batteries suitable for emergency lighting?
Lithium iron phosphate (LiFePO4 or LFP) is well suited for emergency lighting. Compared to alternatives such as nickel-cadmium (NiCd) and nickel-metal hydride (NiMH), lithium iron phosphate (LFP) batteries offer several advantages:
1. Energy efficiency.
LFP is more efficient than NiCd in two ways.
--Self-discharge. All rechargeable batteries lose charge over time, but the rate with LFP is only 3-5% per month. NiCd loses 15% in the first 24 hours, then drops to 10-20% per month (depending on temperature).
--Charging efficiency. During the charging process of any battery, energy is lost in the form of heat. the charging efficiency of LFP is very high, about 95%. the charging efficiency of NiCd is also very high, but only in the early stages of charging. Once the battery reaches 70% capacity, it starts to generate heat and the charging efficiency drops to 85%.
2. Long life.
LFP batteries have little to no memory effect, so their performance remains almost constant until the end of their service life, which is usually defined as 70% of their rated capacity. Typically, LFP batteries have a life span of 8-10 years.
Performance Curves of LiFePO4 Cell:
1. LiFePO4 Cell Charge Curve (Charge at 0.1C)
2. LiFePO4 Cell Discharge Curve (Discharge at 0.2C )
3. LiFePO4 Cell Charge Efficiency At Different Temperature
4. LiFePO4 Cell Cycle Life Curve
5. LiFePO4 Cell Capacity Change At Smart Floating Charge At 55 degree
