LiFePo4 Batteries–Lithium iron phosphate Battery

LiFePo4 battery cells & Lithium iron phosphate Battery Packs

Lithium iron phosphate battery, also called LFP Batteries, is one of the more recently-developed chemistries for rechargeable batteries, and is a variation of lithium ion chemistry. Rechargeable lithium iron phosphate battery packs use LiFePO4 as the cathode material.

CMXbattery manufactures custom lithium iron phosphate battery packs and assemblies for many applications. Our battery design team uses the latest mechanical and electronic design tools to optimize the reliability, safety, and manufacturability of your custom battery packs. This gives you the most cost effective and dependable rechargeable lithium iron batteries for your specific needs.

  • Chemistry offers a longer cycle life than other lithium-ion.
  • LiFePO4 has higher current or peak-power ratings than LiCoO2.
  • Lithium iron phosphate cells are much harder to ignite in the event of mishandling (especially during charge) although any fully charged battery can only dissipate overcharge energy as heat.

Lithium iron phosphate (LiFePO4 or LFP) is the safest of the mainstream li-ion battery types. The nominal voltage of a LFP cell is 3,2V (lead-acid: 2V/cell). A 12,8V LFP battery therefore consists of 4 cells connected in series; and a 25,6V battery consists of 8 cells connected in series.

LiFePo4 battery Characteristics

The Most important characteristics to considered on LiFePo4 batteries include the following:

  • Voltage
  • Capacity
  • Power Rating
  • Operating Temperature
  • Dimensions
  • Cost
  • Availability

If your project requires more voltage than your battery provides it is possible to increase the voltage by connecting multiple cells in series. Also, by connecting cells in parallel, you can increase the overall current capacity (run time) of the battery.

Why USE LiFePo4 batteries

Compared to lead acid batteries, lithium batteries offer significant advantages, including improved discharge efficiency, longer life span and the ability to deep cycle while maintaining performance. While they often arrive with a higher price tag, minimal maintenance and infrequent replacement makes lithium a worthwhile investment and smart long-term solution.

Although LiFePO4 batteries aren’t new, they’re just now picking up traction in commercial markets. Here’s a quick breakdown on what distinguishes LiFePO4 from the other lithium battery solutions:

Safety And Stability

Lithium iron phosphate Batteries are best known for their strong safety profile, the result of extremely stable chemistry. When subjected to hazardous events, such as collision or short-circuiting, they won’t explode or catch fire, significantly reducing any chance of harm.

If you’re selecting a lithium battery and anticipate use in hazardous or unstable environments, LiFePO4 could be your best choice.


Perform well in several areas, especially life span. Service life usually clocks in at five to six years, and cycle life normally exceeds other lithium formulations by 300 or 400%. However, there’s a tradeoff. Energy density is typically lower than certain counterparts, such as cobalt and nickel oxide, meaning you’ll lose some capacity for the price you pay – initially, at least. A slower rate of capacity loss compared to other formulations might offset the tradeoff to some degree. After a year, a LiFePO4 cell typically has approximately the same energy density as a LiCoO2 lithium ion cell.

Battery charging time is also considerably reduced, another convenient performance perk.

If you’re looking for a battery to stand the test of time and charge quickly, LiFePO4 is the answer. However, remember that you might be trading density for longevity: If you need more raw power for a large application, other lithium technologies may serve you better.

Environmental Impact

LiFePO4 batteries are non-toxic, non-contaminating and contain no rare earth metals, making them an environmentally conscious choice. Lead acid and nickel oxide lithium batteries, by comparison, carry significant environmental risk (especially lead acid, as internal chemicals degrade structure over team and eventually cause leakage).

If you’re not sure what will happen to your batteries after you’ve exhausted them and want to guarantee minimal impact to the environment, choose LiFePO4 over other formulations.

Space Efficiency

Also worth mentioning is LiFePO4’s space-efficient characteristics. At one-third the weight of most lead-acid batteries and almost half the weight of the popular manganese oxide, LiFePO4 provides an effective way to make use of application space and reduce overall weight.

Trying to get as much battery power as possible while keeping weight down? LiFePO4 is the way to go.

If you’re looking for a lithium battery that trades rapid energy delivery for safety, stability, long-term performance and low environmental risk, consider powering your application with LiFePO4.

Pros and Cons of Lithium Iron Phosphate Batteries

CMXbattery produces custom lithium iron phosphate battery packs that can be used for a wide range of custom applications. Our rechargeable lithium iron battery packs use a lithium-ion-derived chemistry that shares many of the same advantages with other lithium ion battery chemistries.

Custom LFP Battery Pack Advantages:

Compared to other battery options, custom lithium iron phosphate battery packs provide superior thermal and chemical stability. This allows for improved safety characteristics over lithium-ion batteries that utilize less-safe cathode materials. Rechargeable lithium iron batteries are also virtually incombustible due to mishandling during the charge and discharge processes, which means that they can handle higher temperatures without significant damage. Other major advantages for LiFePO4 when compared to other Li-ion chemistries include higher rate discharge capability and longer cycle life.

Custom LiFePO4 Battery Pack Disadvantages:

The energy density of custom lithium iron phosphate battery packs, both by energy and volume, is somewhat lower than that of LiCoO2 cells and batteries. However, while LiFePO4 cells have lower voltage and energy density than other Li-ion cells, this disadvantage is offset over time by a slower rate of capacity loss (greater calendar-life) when compared with other lithium-ion battery chemistries, such as LiCoO2 cobalt or LiMn2O4 manganese spinel.

Like other lithium-ion cells, lithium iron cells and batteries are available in Energy and Power types that provide either better power or energy characteristics, depending on whether a longer run time or high rate discharge is required.
