What is LiFePO4 battery?
LiFePO4 battery is a type of lithium battery built from lithium iron phosphate. lithium battery catalog contains batteries as below
Lithium Titanate (LTO)
Lithium Cobalt Oxide (LiCoO22)
Lithium Manganese Oxide (LiMn2O4)
Lithium Iron Phosphate Battery (LiFePO4 )
Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2)
Lithium Nickel Cobalt Aluminum Oxide (LiNiCoAlO2)
LiFePO4 battery is a type of lithium battery use lithium iron phosphate as the cathode material, and graphitic carbon electrode with a metallic backing as anode

Benefit of LiFePO4 Battery
1, Safe, Stable Chemistry
Lithium battery safety is important. we usually heard news regarding exploding due to batteries have made that clear. One of the most important feature that LiFePO4 has over other batteries is safety. LiFePO4 is the safest lithium battery type. It is the safest of any batteries, in actual
Overall, LifePO4 battery has the safest lithium chemistry. As lithium iron phosphate material has better thermal and structural stability features. While other batteries don’t have such feature level as LiFePO4, LiFePO4 is incombustible. It can withstand high temperatures without decomposing. It is not prone to thermal runaway, and will keep cool at ambient temperature.
If you subject LiFePO4 battery to harsh temperatures or dangerous case (like short circuiting or a crash) it will not occur a fire or explode.
2, Environmental Safety
LiFePO4 battery is formerly a boon to our earth because they are rechargeable. But the environmental friendliness does not stop this. Different from lead acid or ni-cd battery, LiFePO4 is not toxic and doesn’t leak.
You can re-cycle LiFePO4 battery as well. But you don’t need to do that frequently, as they last long cycle life around 5000 times. It means you can charge them at least 5000 times, while lead acid batteries is only about 300 cycles.
3, Excellent Effectiveness and Performance
You need safe, non-toxic batteries. but you also need batteries that performs well. Stat below certify LiFePO4 batteries deliver all them even more features:
Charge efficiency: LiFePO4 batteries could reach full charge within two hours or less.
Self discharge rate: Only 2% per month. (while lead acid batteries are 30% ).
Runtime is longer than lead acid /other lithium batteries.
Consistent power: same performance even when life cycle is less than 50%, free maintenance.
4, Small and Light
Other factor weigh in to make LiFePO4 battery better. Speak of weighing–they are total light weight. In fact, they are almost 50% lighter than lithium manganese oxide batteries. 70% lighter than lead acid batteries.
When you utilize LiFePO4 batteries in a vehicle, this means less gas and more flexibility. LiFePO4 batteries are compact as well, save space on your solar system, boat, RV, EV, scooter or industrial application.
5, Long life cycle
LiFePO4 battery last at least 2000 cycles with an average discharge of 100%. This can even go up to 12000 times when the battery be discharged to 20%! LiFePO4 battery is therefore real cyclical power system that continue while other battery stop. by comparison, traditional lead acid batteries lasts 500 cycles at most. Long life cycle makes LiFePO4 batteries also a smart economical choice.
Compare LiFePO4 and Lithium-Ion Batteries
LiFePO4 batteries are not perfect for wearable devices like smart watches. As they have a lower energy density compared to other lithium ion batteries. It means, for application like solar energy storage system, RV, boat, EV, golf cart, and electric motorcycle, LiFePO4 is the best by far.
Indeed the life cycle of LiFePO4 batteries are more than 5 times of other lithium ion batteries.
It is the safest lithium battery type in the market as well, safer than lithium ion and many other battery types.
Last but not least, LiFePO4 batteries can not only reach 3,000-5,000 cycles or more… They can reach 100% DOD (depth of discharge). Why does that matter? Because it means, with LiFePO4 batteries , you do not need to worry about over discharging issues.
Also, you could utilize it for a longer phase as a result. Actually, you can use good quality LiFePO4 batteries for many years longer than Lithium-Ion Batteries. Up to 12000 cycles,
It is approximately ten years. Therefore average cost over time is better than li-ion batteries. That is how LiFePO4 batteries stack up compared to lithium ion batteries.
