Lithium Iron Phosphate (LFP) batteries have several significant advantages in electric vehicles, the following are the main advantages:

1. High security

• Good thermal stability: lithium iron phosphate batteries have a high thermal runaway temperature, usually above 500°C, compared to ternary lithium batteries, which have a low thermal runaway temperature. Therefore, in a high temperature environment or in the event of a collision, lithium iron phosphate batteries are less prone to fire or explosion.

• Stable chemical properties: The chemical properties of lithium iron phosphate material itself are relatively stable, and it is not easy to react with the electrolyte, further improving the safety of the battery.

2. Long cycle life

• Charge and discharge times: lithium iron phosphate battery cycle life is long, generally can reach more than 2,000 times, and some can even reach more than 3,000 times. This means that the battery can maintain high performance for a longer period of time, reducing the frequency of replacement.

• Low self-discharge rate: The self-discharge rate of lithium iron phosphate batteries is low, and the power loss is small even if it is not used for a long time.

3. Be environmentally friendly

• No heavy metal pollution: lithium iron phosphate batteries do not contain heavy metals (such as cobalt, nickel, etc.), the impact on the environment after waste is small, and recycling is relatively simple.

• Abundant raw materials: The raw materials of lithium iron phosphate (iron, phosphorus, etc.) are widely distributed around the world, and the price is relatively stable, reducing the dependence on rare metals.

4. Cost effective

• Low material cost: Due to the low cost and stable supply of lithium iron phosphate materials, the overall manufacturing cost of lithium iron phosphate batteries is relatively low.

Low maintenance costs: Due to its long life and high reliability, subsequent maintenance and replacement costs are also low.

5. Good low temperature performance

• Wide operating temperature range: lithium iron phosphate batteries can work normally in a wide temperature range, especially in low temperature conditions, to ensure the normal use of electric vehicles in cold areas.

6. Energy density is gradually increased

Although the energy density of lithium iron phosphate batteries is traditionally lower than that of ternary lithium batteries, with the progress of technology, new lithium iron phosphate batteries (such as CTP technology in the Ningde era and BYD blade battery technology) have greatly improved the energy density, and some models have an energy density close to or even more than some ternary lithium batteries.
