What is a lithium iron phosphate battery? 

A lithium iron phosphate battery is a type of lithium-ion battery whose positive electrode is built with iron phosphate (LiFePO4). The negative electrode of a lithium iron phosphate battery is made of carbon material. The monomer voltage rating is 3.2V. The charge cut-off voltage of the lithium ion-phosphate is 3.6V~3.65V.


Modern energy in the automobile industry


Lithium iron phosphate (LiFePO4) batteries have become common in passenger cars, logistic vehicles, buses, and low-speed electric vehicles among others. Among the many reasons why lithium iron phosphate car batteries are highly preferable are the low cost and safety advantages that they bring.


The application of lithium iron phosphate batteries in the wide range of electric vehicle industry not only improves vehicle safety. It also supports in the marketization of a wide range of electric cars. This greatly eliminates the anxiety of completely electric cars such as price, safety, battery issues, and mileage. 


Power storage market

Lithium iron phosphate battery offers unique benefits when it comes to power storage. It comes with:

  • Low rate of discharge
  • Lacks memory effect
  • High energy density
  • Protection of the green environment
  • Long lifespan
  • High working voltage


Lithium iron phosphate battery will support effortless expansion which is suitable for storage of large-scale electricity. 

The rise and growth of the power/energy storage market in the modern days have opened up new emerging markets for the use of lithium iron phosphate. 


Another benefit of the lithium iron phosphate battery is its mobility and transferability. The features associated with the lithium batteries make it easy to transfer them to new energy storage fields. This extends the value chain and promotes the establishment of other new business models. 


This has made the energy storage systems that are made with lithium-ion batteries become more marketable. Based on market research, the use of lithium iron phosphate extends to electric buses, user-side, electric trucks, and grid-side energy frequency modulation among others. 


LiFePO4 Battery serves every industry

Apart from the automobile industry where lithium iron phosphate battery has made quite a significant difference, below are other areas where the LiFePO4 Battery has made a difference:


Fishing boats: The less time required to charge the lithium-ion phosphate battery means that they can spend a lot of time outside on the water. The less weight also makes them ideal for use in boats. It becomes simple to navigate and propel the boat at high speed especially when competitive fishing is ongoing.

Mobile scooters: You no longer have to worry about any dead weight slowing you down. With lithium iron phosphate batteries, you can easily charge little enough to take you to your destination without causing any damage to the it. 

Solar power storage: The lightweight lithium-ion phosphate (LiFePO4) batteries enable you to take them anywhere. This can even be on a mountain where you need to store power from the sun without any struggle.

Commercial applications: Quality and long-lasting lithium-ion phosphate (LiFePO4) batteries are the toughest and safest lithium batteries that you can get. This makes them highly preferable when it comes to liftgates, floor machines, and many other commercial applications.

Unique applications: Apart from the few examples above, lithium-ion phosphate (LiFePO4) batteries can be used in many other areas as many more markets emerge. This includes electronic cigarettes, emergency lighting, flashlights, and radio equipment among others. 

The advantages of lithium-ion phosphate (LiFePO4) batteries

  • Long lifespan


Lithium iron phosphate (LiFePO4) will guarantee you a long enough lifespan. This can be two to even four times longer compared to that offered by lithium-ion batteries. The lifecycle of a Lithium iron phosphate (LiFePO4) battery is around 5000 times. 


Its lifespan can go up to 10 years of service. The Lithium iron phosphate (LiFePO4) battery can serve you for a long since it has the ability to remain stable even at high temperatures. 


In addition to that, you can store lithium iron phosphate (LiFePO4) batteries for a much longer period without any signs of degradation. It is this long life cycle that makes them perfect for use in solar energy storage systems. 


  • Safety


Lithium iron phosphate (LiFePO4) batteries are the safest compared to other energy storage solutions that are available on the market. This is brought about by their excellent thermal performance as well as their chemical stability. Some of the features that provide safety include:

  • Internally built safety fuse
  • Temperature protection
  • Steel cover for explosion prevention

To ensure that these safety measures are met, the Lithium iron phosphate (LiFePO4) battery must pass every safety test. Some of these safety tests include:

  • Short circuit
  • Temperature
  • Drop
  • Overcharge
  • Low-pressure tests
  • Impact 


  •  Depth of Discharge

Lithium iron phosphate (LiFePO4) battery can get discharged completely and still not affect delivered capacity. With this advantage, you will be able to connect several Lithium iron phosphate (LiFePO4) batteries in order to increase your storage capacity. The battery is discharged at different rates without damaging it. 


  • Environmentally Friendly


The Lithium iron phosphate (LiFePO4) battery is the most environmentally friendly energy storage system. The best lithium-ion phosphate (LiFePO4) is made of materials that are non-toxic. This saves the environment from pollution. These materials are:

  • Iron
  • Copper
  • Graphite

These are materials that can be reclaimed or used in the making of new lithium-ion phosphate (LiFePO4) batteries. Instead of metal oxides contained in other batteries, lithium iron phosphate (LiFePO4) batteries have phosphate salts. Phosphate salts have a very low risk when it comes to environmental contamination. 


What are the recommended safety precautions when handling a Lithium iron phosphate (LiFePO4) battery?


 The installation and maintenance of lithium-ion phosphate (LiFePO4) batteries should be done by qualified personnel. Below are some of the precautionary measures you should pay attention to when handling them. 

  • Never touch the negative and positive poles when the battery is in the box
  • Always have protective devices like rubber gloves when operating the battery
  • Avoid the use of external force to puncture, damage, or dismantle the battery
  • Do not put the battery in extreme temperatures, corrosive places, or near strong magnetic fields. 



With all the benefits that come with the use of a lithium iron phosphate (LiFePO4) battery, it’s no doubt that this is the way to go. It is the most cost-effective way of storing energy.
