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.
3.Large capacity. Lithium iron phosphate battery has a larger capacity than ordinary battery (lead acid, etc.), according to the capacity density of battery, the energy density of lead-acid battery is about 40wh / kg, and the energy density of mainstream lithium iron phosphate battery in the market is above 90Wh / kg.
4. No memory effect. No matter what state the battery is in, it can be used as soon as it is charged. There is no need to discharge it before charging.
5. Environmental protection, non-toxic and pollution-free. Lithium iron phosphate battery is generally considered to be free of any heavy metals and rare metals (Ni MH batteries need rare metals), non-toxic (SGS certification), pollution-free, in line with European ROHS regulations, green environmental protection batteries.
6.High temperature resistance. The peak temperature of lithium iron phosphate can reach 350 to 500 ℃, while that of lithium manganate and lithium cobalt oxide is only about 200 ℃.
