26650 LiFePO4 batteries are mainly used to replace traditional nickel-chromium and nickel-hydrogen batteries in miner’s lamps, flashlights, power tools, toys, instruments, up-back power supplies, communication equipment, medical equipment, unique lamps, etc. If you are looking to find a reliable and customized 26650 LiFePO4 battery pack manufacturer in China, Nuranu is a good choice for you.
What is 26650 LiFePO4 battery
The meaning of the 26650 LiFePO4 battery, that is, the diameter of the battery is 26mm, the length is 65mm, and the battery is cylindrical, it is also a kind of lithium battery. Commonly used 26650 LiFePO4 battery including nickel cobalt manganese anode inr26650-3.6v-4500mah, lithium iron phosphate ifr26650-3.2v-3200mah etc.
How does 26650 LiFePO4 battery work ?
The 26650 LiFePO4 battery can be charged and discharged due to the movement of lithium ions on its positive electrode. That is, when the battery is charged, active lithium ions appear in the positive electrode of the LiFePO4 battery, and the lithium ions move to the negative electrode and are embedded in the layered structure of the negative electrode. The negative data system is graphite, which is a layered structure of carbon. It has many micropores. When lithium ions move to the negative electrode, they become embedded in the micropores.
In the same way, when the battery is discharged, the lithium ions buried in the carbon layer of the negative electrode will come out and move to the positive electrode. The more lithium ions returned to the positive electrode, the greater the discharge capacity.
Advantages of 26650 LiFePO4 battery
26650 LiFePO4 batteries are mainly used to replace traditional nickel-chromium batteries and nickel-hydrogen batteries in miner’s lamps, flashlights, power tools, toys, instruments, ups back power supplies, communication equipment, medical equipment, special lamps, etc. Its advantages related to nickel-chromium batteries and nickel-metal hydride batteries are mainly reflected in the following aspects:
1. High energy density and low self-discharge rate
The capacity of 26650 LiFePO4 battery is equal to 1.5-2 times of the quality of nickel-hydrogen battery. The internal resistance of 26650 domestic LiFePO4 battery is less than 60m, which greatly reduces the power consumption from the battery, and prolonging the use time.
2. Safe charging and discharging function
The 26650 LiFePO4 battery has no memory effect, does not distinguish when heated, has high safety performance, and has a long service life.
3. High voltage
The voltage of 26650 LiFePO4 battery is generally above 3.6 and 3.7V, which is much higher than that of nickel-chromium batteries and nickel-hydrogen batteries.
4. Can be flexible packed and configured
Manufacturer can design LiFePO4 battery pack either in series or parallel
5. Environmentally friendly and pollution-free
