LiFePO4 batteries and Ternary lithium batteries are widely used in our life. Do you know anything about these two kinds of batteries?
In this article, let’s compare these two batteries and learn more about their advantages(Learn: Lithium Ion Battery Pros and Cons: What You Need to Know).
What Is LiFePO4 Battery and Ternary Lithium Battery?
LiFePO4 battery, also LFP battery, stands for lithium iron phosphate battery. It is one type of lithium battery that utilizes lithium iron phosphate as the positive electrode material.
Ternary lithium battery (learn: Arctic Lithium Battery: What You Should Know) is also a type of lithium battery. Its positive electrode material is made of a combination of nickel, cobalt, and manganese/aluminum.
Both LiFePO4 battery and Ternary lithium battery are commonly used in solar (learn: Top 10 Best Batteries for Solar Power Storage) energy systems, UPS, and many other applications.
The Comparison Between LiFePO4 Battery and Ternary Lithium Battery
Lithium iron phosphate battery (learn: What Is Good About HDN Lithium Battery?) is chemically stable and has great safety performance. The internal chemical composition of LiFePO4 batteries begins to decompose only when the temperature reaches 500-600℃. In addition, even if the LiFePO4 battery is damaged, no oxygen molecules will be released and no violent combustion will occur.
The thermal stability performance of the Ternary lithium battery is inferior. The battery starts to decompose at about 300℃.
The most critical indicator to evaluate the performance of a battery is energy density. The energy density of LiFePO4 is about 140Wh/kg.
The energy density of the Ternary lithium battery is about 240Wh/kg. Under the same weight, the energy density of the Ternary lithium battery (learn: What Is Good About HDN Lithium Battery?) is 1.7 times that of the LFP battery.
The low-temperature performance of the LiFePO4 battery is inferior to that of the Ternary lithium battery. The low-temperature limit of the Ternary lithium battery is -30℃. Its discharge performance at low temperatures is good. On the other hand, the temperature limit of the LiFePO4 battery is -20℃.
The LiFePO4 battery has a long lifespan, which is about 3,500 cycles. However, the life of the Ternary lithium battery is shorter than that of the LiFePO4 (learn: Why Should We Choose XT LiFePO4 Batteries) battery. It reaches about 2,000 cycles.
Both LiFePO4 battery and Ternary lithium battery have their advantages. If you need a battery with high safety, you can choose lithium iron phosphate batteries. If you want to use the battery at low temperatures, you can go for Ternary lithium batteries.
