Latest company news about 18650 LiFePO4 vs Ternary Batteries: What's the Difference?

When it comes to lithium-ion batteries, there are many types to choose from, each with its own set of strengths and weaknesses. Two popular types of 18650 lithium-ion batteries are LiFePO4 and ternary batteries. In this article, we'll explore the differences between these two types and compare their capacities.

 

Energy Density:

One of the biggest differences between LiFePO4 and ternary batteries is their energy density. Ternary batteries have a higher energy density, meaning they can store more energy per unit of volume or weight. This makes them ideal for applications that require high energy density, such as electric vehicles and high-performance portable electronics.

 

In comparison, LiFePO4 batteries have a lower energy density, meaning they can store less energy per unit of volume or weight than ternary batteries. However, they make up for this by having a longer cycle life and higher thermal stability. The stable crystal structure of lithium iron phosphate allows the battery to be charged and discharged more times before it starts to degrade, and it is less prone to thermal runaway and fire. LiFePO4 batteries are ideal for applications that require high cycle life and safety, such as energy storage systems and backup power supplies.

 

Capacity:

In terms of capacity, 18650 LiFePO4 batteries typically have a capacity ranging from 1,000 mAh to 3,000 mAh, with a maximum capacity of around 3,500 mAh. On the other hand, 18650 ternary batteries typically have a capacity ranging from 2,000 mAh to 3,500 mAh, with a maximum capacity of around 4,500 mAh. This means that ternary batteries tend to have a higher capacity than LiFePO4 batteries, which is consistent with their higher energy density. However, higher capacity batteries also tend to have a higher cost.

 

Conclusion:

When choosing between 18650 LiFePO4 and ternary batteries, it's important to consider the specific requirements of the application, including energy density, cycle life, safety, and cost. Ternary batteries are better suited for applications that require high energy density, such as electric vehicles and high-performance portable electronics, while LiFePO4 batteries are ideal for applications that require high cycle life and safety, such as energy storage systems and backup power supplies. Ultimately, the choice between these two battery types will depend on the specific needs and constraints of the application.
