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.
Difference between LiFePO4 batteries and Li-ion polymer batteries
Lithium iron phosphate (LiFePO4, LFP) batteries
Lithium iron phosphate is a lithium-ion polymer battery that uses
LiFePO4 as the cathode material and a metal-backed graphite carbon
electrode as the anode.
The LiFePO4 battery, also known as the LFP battery, is a
rechargeable battery. It is the safest type of lithium battery on
the market today. It is small, lightweight, and has a cycle life of
thousands of cycles.
Lithium-Ion Polymer (LIPO) Batteries
A lithium-ion polymer battery is a rechargeable battery that works
primarily on the movement of lithium ions between the positive and
negative electrodes. Lithium-ion batteries use an embedded lithium
compound as the electrode material. The commonly used lithium-ion
battery cathode materials are lithium cobaltate (LCO battery),
lithium manganate (LMO battery), ternary lithium-ion (NCA, NMC
battery), and lithium iron phosphate (LiFePO4 battery).
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
