Таблица аккумуляторов LifePO4 в Китае: сравнение производительности и характеристик

Введение

 

Lithium iron phosphate (LiFePO4) batteries have gained popularity in recent years due to their high energy density, low self-discharge rate, and long cycle life. With the increasing demand for renewable energy and electric vehicles, LiFePO4 batteries have become a preferred choice for many applications. In this article, we will compare the performance and specifications of various LiFePO4 batteries available in the market.

 

Performance Comparison

 

1. Energy Density: LiFePO4 batteries have a lower energy density compared to other lithium-ion batteries such as Lithium Cobalt Oxide (LiCoO2). However, they have a higher energy density compared to lead-acid batteries. The energy density of LiFePO4 batteries ranges from 120 to 170 Wh/kg.

 

2. Cycle Life: LiFePO4 batteries have a longer cycle life compared to other lithium-ion batteries. The cycle life of LiFePO4 batteries ranges from 2000 to 7000 cycles, depending on the type and manufacturer.

 

3. Charging Speed: LiFePO4 batteries have a slower charging speed compared to other lithium-ion batteries. The charging time of LiFePO4 batteries ranges from 2 to 6 hours, depending on the type and manufacturer.

 

4. Discharge Rate: LiFePO4 batteries have a lower discharge rate compared to other lithium-ion batteries. The discharge rate of LiFePO4 batteries ranges from 1C to 3C, depending on the type and manufacturer.

 

 

 

Specifications Comparison

 

1. Voltage: LiFePO4 batteries have a nominal voltage of 3.2 volts per cell. The voltage range of LiFePO4 batteries is between 2.0 volts to 3.65 volts per cell.

 

2. Capacity: LiFePO4 batteries have a capacity range of 20 to 400 Ah, depending on the type and manufacturer.

 

3. Size and Weight: LiFePO4 batteries are available in various sizes and weights. The size and weight of LiFePO4 batteries depend on the type and capacity of the battery.

 

4. Operating Temperature: LiFePO4 batteries can operate in a wide range of temperatures, from -20°C to 60°C. However, the performance of LiFePO4 batteries can be affected at extreme temperatures.

 

Заключение

 

LiFePO4 batteries have several advantages over other lithium-ion batteries and lead-acid batteries. They have a longer cycle life, lower self-discharge rate, and are more environmentally friendly. However, they have a lower energy density and slower charging speed compared to other lithium-ion batteries. It is important to consider the performance and specifications of LiFePO4 batteries before selecting them for any application.
