What does LiFePO4 mean on a lithium battery?

LiFePO4 stands for lithium iron phosphate, which is a type of lithium-ion battery chemistry. It was created in the 1990s as an alternative to other common lithium-ion battery chemistries such as lithium-cobalt oxide (LCO) and lithium-manganese oxide (LMO).

The primary benefit of using LiFePO4 is that it offers higher energy density and improved safety when compared to other lithium-ion chemistries. This is because LiFePO4 has a lower flammability rating and is more stable against thermal runaway than other lithium-ion batteries.

Additionally, LiFePO4 also offers superior cycle life and longer battery charge retention when compared to other lithium-ion types, making it the perfect choice for applications that require longer battery life.

Furthermore, LiFePO4 batteries can also be charged faster than other lithium battery types, making them a great option for quick charging applications.

What is the difference between lithium ion battery and LiFePO4?

The major difference between a lithium ion battery and LiFePO4 is the chemistry of their cells. A lithium ion battery uses a carbon anode, a lithium-ion transition metal oxide cathode, and an electrolyte of lithium salts.

LiFePO4 batteries on the other hand use a lithium iron phosphate cathode, a graphite anode, and an electrolyte of either a lithium salt or a phosphate salt. LiFePO4 batteries generally have a longer life cycle than lithium ion batteries due to their increased resistance to aging.

Furthermore, LiFePO4 batteries are relatively safe and non-combustible making them an appealing option. As well, LiFePO4 cells are slower to degrade under high temperatures where lithium ion batteries can quickly degrade, leading to an unsafe situation.

Lastly, LiFePO4 batteries can handle a higher rate of discharge than lithium ion batteries and can be charged more times than lithium ion batteries, making them more efficient overall.

Can I charge a LiFePO4 battery with a lithium ion charger?

No, it is not recommended that you charge a LiFePO4 battery with a lithium ion charger. LiFePO4 batteries and lithium ion batteries have different charge profiles and use different voltage and current ranges when charging.

LiFePO4 batteries require a much lower voltage range (2. 4V-3. 6V) and current capacity range (0. 2C – 1C) when charging. However, lithium ion batteries require higher voltage range (4. 2V – 4. 35V) and current capacity range (1C – 5C).

Therefore, using a lithium ion charger to charge a LiFePO4 battery could damage it due to the mis-matched voltage and current range. It is therefore recommended that you use a LiFePO4 charger when charging a LiFePO4 battery.
