Everyone knows that lithium batteries can explode, but it's really difficult for you to explode lithium iron phosphate batteries. Here's some knowledge about lithium iron phosphate batteries.

What is LiFePO4 Battery?

The lithium iron phosphate (LiFePO4) battery, also called LFP battery (with "LFP" standing for "lithium iron phosphate"), is a type of rechargeable battery, specifically a lithium-ion battery, which uses LiFePO4 as a cathode material. LiFePO4 batteries have somewhat lower energy density than the more common lithium cobalt oxide (LiCoO2) design found in consumer electronics, but offer longer lifetimes, better power density (the rate that energy can be drawn from them), and are inherently safer. LiFePO4 is finding a number of roles in-vehicle use and backup power.

One important advantage over other lithium-ion chemistries is thermal and chemical stability, which improves battery safety. LiFePO4 is an intrinsically safer cathode material than LiCoO2 and manganese spinel. The FePO bond is stronger than the CoO bond, so that when abused, (short-circuited, overheated, etc.) the oxygen atoms are much harder to remove. This stabilization of the redox energies also helps fast ion migration. As lithium migrates out of the cathode in a LiCoO2 cell, the CoO2 undergoes non-linear expansion that affects the structural integrity of the cell. The fully lithiated and unlithiated states of LiFePO4 are structurally similar which means that LiFePO4 cells are more structurally stable than LiCoO2 cells. No lithium remains in the cathode of a fully charged LiFePO4 cell-in a LiCoO2 cell, approximately 50% remains in the cathode. LiFePO4 is highly resilient during oxygen loss, which typically results in an exothermic reaction in other lithium cells. As a result, 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. Therefore, failure of the battery through misuse is still possible. It is commonly accepted that the LiFePO4 battery does not decompose at high temperatures.[9] The difference between LFP and the LiPo battery cells commonly used in the aeromodelling hobby is particularly notable.


Advantages of LifePO4 battery:
1. Green energy, Non-toxic, non-polluting, a wide range of raw materials, cheap
2. Long life cycle over 2000 times;
3. It without heavy metals and environment friendly.
4. Maintenance free
5. Internal BMS with full protection, the battery has high voltage protection with higher reliability.
6. No memory effect
7. High-temperature performance is good
9. High safety, no explosion, no fire
10. Low self-discharge rate,≤3%/month


* Lithium iron phosphate battery is characterised by outstanding durability, current performance and charging speed. It also has a longer lifetime and is a more lightweight alternative to lead-acid batteries.

* LiFePO4 retain over 80% of their capacity even after 3,000 charging cycles and thus they provide over 7 years of operation. Due to its low self-discharge rate the battery will be fully ready for operation even after a year of storage.

* The long battery life and high durability, low weight and current parameters are the reasons why these batteries are used in leisure vehicles and campers, in boats and in photovoltaics providing power to homes using solar panels.

* Lithium iron phosphate batteries are equipped with a battery management system BMS which monitors not only the charge and discharge of the battery but also the temperature thus ensuring the safety of operation and maximising the battery life.
