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). The result is that the charger in an emergency unit with NiCd or NiMH batteries operates almost continuously, while the charger in the LFP circuit operates at low current during short and infrequent bursts.
--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%. This is important because in normal use, the NiCd cells in emergency light accessories will continue to trickle charge to keep them near 100% capacity.
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.
--The performance (storage) of NiCd and NiMH decreases rapidly with each charge/discharge cycle, so they typically need to be replaced after 3 or 4 years. the emergency lighting routine testing required by BS 5266 helps shorten the life of NiCd batteries. NiCd batteries in new construction projects that have been fully installed during the construction phase typically fail in the first year of their service life, when the main power supply is usually completely shut down overnight. The resulting overnight discharges and daily recharges can degrade NiCd batteries to the point where they can be replaced in the first year of use.
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
