Lithium iron phosphate batteries (LiFePO4) and ternary lithium batteries (NMC, NCA, etc.) are two common lithium-ion battery technologies, and there are some key differences between them

Lithium iron phosphate batteries are more stable at high temperatures and are less prone to thermal runaway or explosion, so they have higher safety.

Ternary lithium batteries are relatively fragile at high temperatures and may have certain safety risks.

Lithium iron phosphate batteries have a long cycle life, often reaching thousands of cycles, making them suitable for applications that require long-term stable performance.

Ternary lithium batteries have a short cycle life, generally around a few hundred to a thousand times, and need to be replaced more frequently.

Ternary lithium batteries usually have a higher energy density and can store more electrical energy in the same volume and weight.

Lithium iron phosphate batteries have a relatively low energy density, larger volume and heavier, so with the same capacity, more space is required.

Lithium iron phosphate batteries are relatively expensive to manufacture, but the overall cost of use may be lower due to their long cycle life.

Ternary lithium batteries are less expensive to manufacture, but the overall cost of ownership may be higher due to the shorter cycle life, which may require more frequent battery replacement.

Considering the above factors, the choice between lithium iron phosphate batteries and ternary lithium batteries depends on specific application requirements, such as safety, cycle life requirements, energy density requirements, and cost considerations.
