What is the Voltage Range and Capacity of LiFePo4 Battery
Lithium iron phosphate battery (LiFePo4) is a kind of lithium ion battery which uses Lithium iron phosphate as cathode material. Lithium iron phosphate battery has the advantages of high safety, long cycle life, multiple discharge, high temperature resistance, etc. It is considered as a new generation of lithium battery. What is the voltage range and capacity of Lithium iron phosphate battery, and what are its advantages and disadvantages?
What is the Voltage Range of LiFePo4
Lithium iron phosphate battery belongs to a kind of lithium battery. It is named because the cathode materials of Lithium iron phosphate battery are mainly phosphorus, acid, iron and lithium compounds. Generally speaking, the voltage range of Lithium iron phosphate battery is basically between 3.2V-3.6V. Among them, the nominal voltage is 3.2V, the high end charging voltage is 3.6V, and the discharge cut-off voltage is 2.0V. However, the positive and negative electrode materials, electrolytes, and production processes used by different manufacturers may vary in terms of performance.
The Lithium iron phosphate battery group reaches the voltage required by the equipment through the series combination of electric cells, and the battery group voltage=N * series number. The commonly used Lithium iron phosphate battery voltages are as follows:
What is the Capacity Range of LiFePo4
The capacity of Lithium iron phosphate battery group is determined according to the capacity and number of cells in parallel, generally according to the specific requirements of electrical equipment. The more Iron(III) phosphate lithium cells in parallel, the greater the capacity.
Common Lithium iron phosphate battery packs have capacities of 10ah, 20ah, 40ah, 50ah, 100ah, 200ah, 400ah, etc.
What are the Advantages and Disadvantages of LiFePo4
What are the Advantages of LiFePo4 Battery
Free of precious metal elements such as cobalt, easy to obtain raw materials, and low cost;
The battery has high temperature resistance, and the temperature of Thermal runaway can reach about 800 degrees, with good safety performance;
The battery cycle life can reach over 3500 times, and some can even reach 5000 times, with a long service life;
The working voltage of the battery is between 3.2-3.4V, which can meet the basic requirements of on-board batteries;
After the battery service life expires, there is still 80% of the stored electricity, which has high recycling value.
What are the Disadvantages of LiFePo4 Battery
Low temperature performance is poor, around -20 degrees Celsius, and the battery attenuation will basically reach around 55%;
The overall production cost of the battery is high;
The battery process performance is unstable and has poor consistency.
