LiFePO4 vs. Lithium Ion Batteries

The battery industry has advanced rapidly in recent years, making superior technologies more affordable. Lithium iron phosphate (also known as LiFePO4 or LFP) is the latest development in this rapidly changing industry.

The LFP battery type has come down in price in recent years — and its efficiency has dramatically improved. It’s surpassing lithium-ion (Li-ion) as the battery of choice for many applications, including off-grid and solar power — and even Electric Vehicles (EVs).

LiFePO4 batteries are similar to Li-ion but have significant advantages that make them the ideal option for consumer-grade backup power solutions.

Advantages of LiFePO4(LFP) Batteries

The LFP battery has long lifespan with over 2000 times life cycles. Lithium iron phosphate battery can lasts 7-8 years.

  • Safety. LiFePO4 batteries have been tested strictly and come into the conclusion that the LFP battery has the limited possibility of exposure even in traffic accident.
  • Fast charge speed with the dedicated charger
  • Heat-resistance. 350-500 degree.
  • Large power capacity
  • Eco-friendly. Non-toxic. No pollution.

Disadvantages of LiFePO4(LFP) Batteries

  • The vibration density of lithium iron phosphate battery is small, and the vibration density is generally around 0.8 to 1.3. Big size.
  • The electrical conductivity is poor, the diffusion rate of lithium ions is slow, and the actual specific capacity is low when the charging multiple is high.
  • The low temperature performance of LiFePO4 battery is poor.
  • The service life of a single lithium iron phosphate battery is long, about 2000 times, but the service life of a lithium iron phosphate battery pack is short, generally about 500 times.

LiFePO4 vs. Lithium Ion Batteries: How Do They Compare?

  • LiFePO4 batteries are safer than Li-ion due to the strong covalent bonds between the iron, phosphorus, and oxygen atoms in the cathode.
  • Li-ion batteries typically have a higher energy density than LFPs. The energy density of a battery is a measure of how much energy it can store per unit of volume or weight. Li-ion batteries can store more power per volume or weight unit than LFPs.
  • LiFePO4 battery banks may weigh slightly more than comparable Li-ion batteries, while some LFPs may be lighter because the metals used in their construction are lighter.
  • LiFePO4 batteries offer a wider operating temperature range. They can function well in temperatures ranging from -4°F (-20°C) to as high as 140°F (60°C).
  • Many Li-ion batteries can go through around 500 charge and discharge cycles before degrading in performance. LiFePO4 batteries can go through thousands of cycles before their performance begins to drop.
