Lithium iron phosphate batteries and ternary lithium batteries are two types of lithium-ion batteries that are widely used at present. They have some differences in electrochemical performance, safety performance, and cost.
1.Electrochemical Properties:
Lithium iron phosphate battery: It has a high discharge platform voltage (about 33V), which can provide a relatively stable output voltage, which is suitable for long-term stable work. High charging and discharging efficiency and long cycle life.
Ternary lithium battery: It has a high energy density and power density, can output a larger current, and is suitable for high-power applications. The charging and discharging efficiency is high, and the cycle life is relatively long.
2.Safety Performance:
Lithium iron phosphate battery: Because of its stable structure, it is less prone to serious safety accidents such as thermal runaway or fire, and is considered to be a relatively safe lithium-ion battery.
Ternary lithium battery: Due to the nickel contained in its cathode material, nickel will react with the oxygen in the electrolyte at high temperatures, causing potential safety hazards. Some measures need to be taken to improve its safety performance.
3.Cost:
Lithium iron phosphate battery: Lithium iron phosphate is a widely available and low-cost raw material, and the manufacturing cost is relatively low.
Ternary lithium battery: Ternary materials contain rare metals, such as cobalt, and the production process is complex, resulting in relatively high manufacturing costs.
In general, lithium iron phosphate batteries have advantages in applications such as electric vehicles that require long-term operation and stable output, while ternary lithium batteries have better performance in scenarios that require high power output. The choice of battery is based on the trade-off of the specific application needs.
