Lithium iron phosphate (LiFePO 4 ), also called LFP, is one of the more recent developments in rechargeable batteries and a variation on lithium-ion chemistry. Lithium iron phosphate rechargeable batteries use LiFePO 4 as the main cathode material . Despite having a lower energy density than other lithium-ion chemicals, lithium iron phosphate batteries can offer better power density and longer life cycles.

Properties of the lithium iron phosphate cell
Here are a few things to consider before choosing a battery for your project:
- rated capacity
- operating temperatur
Once these points are well understood, a cell / battery can be selected that meets the necessary requirements to effectively complete the project. If your project requires more voltage than your battery can deliver, you can increase the voltage by connecting multiple cells in series. You can also increase the total current capacity (runtime) of the battery by connecting the cells in parallel.
Advantages and disadvantages of lithium iron phosphate batteries
As a custom manufacturer of lithium batteries, Lithium Batteries produces custom lithium iron phosphate battery packs that can be used for a variety of custom applications. Our rechargeable lithium iron battery packs use lithium ion derived chemistry that has many of the same advantages with other lithium ion battery chemistries.
Benefits of the Custom LFP Battery
Compared to other battery options, custom lithium iron phosphate battery packs offer superior thermal and chemical stability. This enables improved safety properties compared to lithium-ion batteries that use less safe cathode materials. Rechargeable lithium iron batteries are also practically non-flammable due to incorrect handling during charging and discharging, so that they can withstand higher temperatures without significant damage. Other main advantages of LiFePO 4 compared to other Li-ion chemicals are a higher discharge rate and a longer lifespan.
Disadvantages of the custom LiFePO 4 battery pack
The energy density of customer-specific lithium iron phosphate battery packs is somewhat lower than that of LiCoO 2 cells and batteries, both in terms of energy and volume. Although LiFePO 4 cells have a lower voltage and energy density than other Li-ion cells, this disadvantage is offset over time by a slower loss of capacity (longer calendar life) compared to other lithium-ion battery chemicals, such as z LiCoO 2 cobalt or LiMn 2 O 4 manganese spinel.
Like other lithium-ion cells, lithium-iron cells and batteries are available in the Energy and Power types, which offer either better performance or energy properties, depending on whether a longer run time or a high discharge rate is required.

Applications for lithium-ion phosphate batteries
Rechargeable lithium iron battery packs are a popular choice for electric vehicles because of their fast charge and high discharge capabilities, as well as their long cycle and calendar life. Power tool manufacturers have also taken over LFP-Chemie for the same reasons. Medical device manufacturers and defense companies are adopting LFP chemistry for its inherent safety. Industries that regularly use LFP batteries include:
- Manufacturer of electric cars
- Power tool company
- Medical device manufacturer
