LiFePO4 Battery Performance and Test Conditions
1. Standard test conditions
Test should be conducted with new batteries within one week after
shipment from our factory and the batteries shall not be cycled
more than five times before the test. Unless otherwise specified,
test and measurement shall be done under temperature of 20±5℃ and
relative humidity of 45~85%. If it is judged that the test results
are not affected by such conditions, the tests may be conducted at
temperature 15~30℃ and humidity 25~85%RH.
2. Standard Charge/Discharge
Standard Charge: 0.2C
Charging shall consist of charging at a 0.2C constant current rate
until the battery reaches 14.6V. The battery shall then be charged
at constant voltage of 14.6 volts while tapering the charge
current. Charging shall be terminated when the charging current has
tapered to 0.05CA. Charge time: Approx 7.0h, The battery shall
demonstrate no permanent degradation when charged between 0 ºC and
45 ºC.
Standard Discharge: 0.2C
Battery shall be discharged at a constant current of 0.2C to 10V @
20º ± 5C
Are lithium iron phosphate (LFP) batteries suitable for emergency
lighting?
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
