Features For Cylindrical 3.2V LiFePO4 Battery:
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. Environment The RoHS directive prohibits the use of cadmium because it is a dangerous contaminant.
--Cadmium is highly toxic. Cadmium is highly toxic to almost all animals and many plants. It is also very persistent in the environment and does not easily combine with other elements that make it harmless. Therefore, NiCd batteries must be recycled very carefully. lFP batteries must also be recycled, but the materials used are inherently less hazardous than those used in NiCd and NiMH batteries.
--The future use of cadmium is limited. Since quality alternatives to cadmium are available for batteries, it is expected that the RoHS directive will be amended to remove the exemptions allowed so far.
