Lithium iron phosphate batteries and ternary lithium batteries each have their own advantages and disadvantages. The choice of battery depends on the specific needs and usage environment.
1. Energy density: Ternary lithium batteries have higher energy density, smaller size and lighter weight, and are suitable for scenarios requiring the weight of the vehicle body.
2. Safety performance: Lithium iron phosphate batteries perform better in acupuncture tests, have strong high temperature stability, are not easy to burn, and are safer.
3. Lifespan: The charge and discharge cycle life of lithium iron phosphate batteries is longer, ensuring longer use.
4. Low temperature performance: Ternary lithium batteries have better low temperature performance and can fooperate at lower temperatures.
5. Price: The cost of lithium iron phosphate batteries is lower and the price is more affordable.
Are lithium iron phosphate batteries durable? What are the advantages?
The advantages and disadvantages of lithium iron phosphate and ternary lithium batteries are as follows:
1. Advantages and disadvantages of lithium. iron phosphate batteries
1. Advantages of lithium iron phosphate batteries
The raw materials are simple and safe, do not contain heavy metal elements such as cobalt, and have a high recycling value. Basically, spontaneous combustion can only occur when the battery temperature exceeds 800 degrees and the safety is relatively good.
2. Disadvantages of lithium iron phosphate batteries
The overall size and weight of the battery are relatively important, the convenience is not very good, and the manufacturing cost is high.
2. Advantages and disadvantages of ternary lithium batteries
1. Advantages of ternary lithium batteries
The battery voltage is also high. like 3.7V, which can provide more sufficient power for vehicles. The loading speed is also faster. Although the overall size and weight are smaller, the performance is still very good and the power output is higher.
2. Disadvantages of ternary lithium batteries
Battery life is relatively short, perhaps less than 2,000 times.
The difference between lithium iron phosphate batteries and ternary lithium batteries:
1. Lithium iron phosphate batteries refer to lithium-ion batteries that use lithium iron phosphate as the cathode material, tansay ternary lithium batteries refer to lithium ion batteries that use lithium nickel cobalt manganate as the cathode material.
2. The energy density is different. The energy density of lithium iron phosphate battery cells is about 110 Wh/kg, while the energy density of ternary lithium battery cells is about 200 Wh/kg.
3. Different temperature resistance. Under high temperature conditions, ternary lithium batteries decompose at 200°C, while the decomposition temperature of lithium phosphate batteries is 800°C. Therefore, lithium iron phosphate batteries are more resistant to high temperatures and less likely to catch fire.
4. The life of the charge and discharge cycle is different. The number of charge and discharge cycles of lithium iron phosphate batteries can reach 3,500-5,000 times, whilee the number of cycles of ternary lithium batteries is only about 2,500 times.

Each battery has different advantages, the advantages of lithium iron phosphate batteries mainly include the following aspects:
Firstly, good safety performance
The PO bond in lithium iron phosphate crystal is stable and difficult to decompose even at high temperatures Or when overcharged, the structure will not collapse, heat up, or form strong oxidizing substances like carbon oxide. lithium and cobalt, it therefore offers good safety.
Second, long life
The lithium iron phosphate battery has a lifespan of more than 2,000 times. It can reach 2,000 times with one chargestandard (5 hour rate). The theoretical lifespan will reach 7 to 8 years.
Third, good high temperature performance
The electric heating peak of lithium iron phosphate can reach 350℃ - 500℃, while the maximum value of manganate of lithium and lithium cobalt oxide is only about 200℃. The operating temperature range is wide (-20°C to +75°C), and the maximum value of lithium iron phosphate electric heater can reach 350℃-500℃ with high temperature resistance.
Fourth, large capacity
It has a larger capacity than ordinary batteries (lead-acid, etc.). 5AH-1000AH (single unit)
Fifth, no memory effect
When rechargeable batteries are often fully charged and not fully discharged, the capacity will quickly fall below the value of nominal capacity. this phenomenon is called memory effect. The batteries haveNickel-metal hydride and nickel-cadmium batteries have memory, but lithium iron phosphate batteries do not have this phenomenon. Regardless of the state the battery is in, it can be charged and used at any time, and there is no need to discharge it first. then charge it.
Sixth, light weight
The volume of a lithium iron phosphate battery with the same specifications and capacity is 2/3 that of a lead-acid battery, and its weight is 1/3 that of a lead acid battery.
Seventh, environmental protection
The battery is generally considered to contain no heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certified), and non-polluting, complies with European RoHS regulations and constitutes an absolute ecological battery certificate.
