Advantages and disadvantages of lithium iron phosphate and lithium ion batteries

Types of lithium batteries:Lithium iron phosphate batteries and lithium ion batteries have their own advantages and disadvantages, the advantages of lithium iron phosphate batteries are mainly:

Long cycle life. The cycle life of lithium iron phosphate batteries is usually more than 2,000 times, and the capacity can be maintained at more than 80%.

Fast charging and discharging. The charging and discharging efficiency of lithium iron phosphate batteries is high and can reach more than 95%, using a special charger, can be fully charged in a short time.

Good safety performance. The cathode material of LiFePO4 battery has good thermal stability, not easy to decompose or burn, and can remain stable even in high temperature environment.

Strong temperature adaptability. Lithium iron phosphate batteries have good high temperature resistance, and the hot air value can reach 350 to 500 degrees Celsius.

Green . Lithium iron phosphate batteries do not contain heavy metals and toxic substances, and are friendly to the environment.

No memory effect. Lithium iron phosphate battery will not affect its performance because of the charging and discharging method.

The disadvantages of lithium iron phosphate battery are mainly:

Small vibration density. The positive electrode of lithium iron phosphate batteries has a small solidification density, resulting in a larger volume.

Poor electrical conductivity. The conductivity of lithium iron phosphate batteries is poor, lithium ion diffusion is slow, resulting in low actual specific capacity at high times charge and discharge.

Poor low temperature performance. The performance of lithium iron phosphate batteries decreases in low-temperature environments.

Short battery pack life. Although the individual battery life is long, the life of the battery pack is relatively short.

The advantages of lithium-ion batteries are mainly:

High energy density. The actual specific energy of 100ah lithium ion battery is large and can reach about 555Wh/kg.

Long cycle life. Generally can reach more than 500 times, or even more than 1000 times.

Good safety performance. 48 volt lithium battery do not contain elements that pollute the environment, such as cadmium, lead, mercury and so on.

Disadvantages of lithium-ion batteries are mainly:

High cost. The material preparation cost and battery manufacturing cost of 24v li ion battery are high.

Low yield rate. Lithium-ion batteries have a low yield and poor consistency.
