Lithium Iron Phosphate Battery (LiFePO4)

A Lithium Iron Phosphate Battery (LiFePO4 or LFP) have been known since 1996. This battery chemistry offers clear advantages. LiFePO4 cells are significantly safer than LiCoO2 cells and compared to lead batteries we see that with a LiFePO4 battery more than 100% of the nominal capacity can be used.




Characteristics of a lithium iron phosphate battery

Batteries and accumulators of Elfa



LiFePO4 batteries have different characteristics which will be explained here.


No maintenance: LiFePO4 batteries require no maintenance. The ‘Battery Management System’ ensures that all cells are charged in a balanced manner. They can be mounted in any position and there is no need to ventilate the room.


100% deep discharge: Unlike conventional lead-acid batteries, LiFePO4 cells may be 100% fully discharged. Meanwhile, they certainly achieve 5x as many cycles as lead acid batteries. In addition, these types of batteries have a very high energy density and do not contain any toxic, heavy metals. This makes them a lot more environmentally friendly than NiCad and lead-acid batteries. In addition, these batteries are lightweight, which is a big advantage compared to lead batteries.


Good performance with cold: LiFePO4 batteries, like any battery, lose capacity in cold environments. However, the loss in these variants is minimal. At a temperature of -20˚C they still have a capacity of 80%. For comparison, a good AGM lead battery delivers only 30%. LiFePO4 batteries can be used in a temperature range of -45°C to +70°C.


Non-combustible: A LiFePO4 battery is non-flammable in case of damage or improper handling during charging and discharging. They can withstand high temperatures without disintegrating or splashing.


Longer life span: The phosphate technique offers a longer life span. LiFePO4 cells are therefore very resistant to extreme ambient temperatures. A standard lead battery loses its capacity below freezing point and at high temperatures the life span decreases considerably.


Advantages of LiFePO4 batteries

  • LiFePO4 batteries require no maintenance.
  • Can be mounted in any position
  • LiFePO4 battery can be deeply discharged 100%
  • Reach at least 5 times as many cycles as lead batteries
  • High energy density
  • Lightweight


Disadvantages of LiFePO4 batteries

  • High price
  • Limited supply

Case study: Portpay

Amsterdam’s canals are always very busy. Thousands of boats belonging to residents, visitors and tourists sail there every day. To maintain safety and prevent inconvenience, the boat movements in the canals are monitored. The organisation Portpay is responsible for this.

Portpay uses computers with Linux software and cameras for data collection. These are directed at important intersections along the canals, enabling them to collect all relevant data. The information obtained is then sent to the central database.


To ensure that the system functions 24 hours a day, 7 days a week, lithium iron phosphate battery technology was chosen.


Elfa has made a stainless steel housing with a LiFePO4 battery in it that meets the customer’s requirements. During the summer nights the batteries are charged for 7 hours and then operate (discharge) for 17 hours during the day.


Because of their high energy density and fast charging time, they are ideal for Portpay’s smart monitoring system.
