What Are The Voltage Parameters And Advantages Of 18650 Li-Ion Battery?

18650 lithium ion battery voltage parameters:

1, the core of 18650 lithium-ion battery voltage is the working voltage, also called the nominal voltage, is 3.7V, which is equivalent to three series-connected nickel-cadmium or nickel-metal hydride batteries, there are also some domestic battery manufacturers designed to work with a voltage of 3.6V.

2, the charging limit voltage: this is the highest limit on the 18650 battery voltage, 4.2V, 18650 lithium-ion battery charging process is the 18650 battery voltage from the work of the 3.7V up to 4.2V process, the end of the process, said the battery is fully charged state. More than 4.2V, is overcharged, will cause harm to the battery.

3, the discharge termination voltage: that is, the 18650 lithium-ion battery voltage down to the minimum operating voltage should not continue to discharge, 2.75V, if the battery is put below the termination voltage, it is over-discharge, over-discharge will make the 18650 battery electrode structure is damaged, so that the lithium-ion irreversible reaction occurs, seriously affecting the life of the 18650 battery.

Advantages of 18650 Li-ion battery:

1. large capacity. 18650 lithium-ion battery capacity is generally 1200mah ~ 3600mah, while the general battery capacity is only 800 or so, if the combination of 18650 lithium-ion batteries into 18650 lithium-ion battery packs, the 18650 lithium-ion battery packs can break through the 5000mah casually.

2. Long life: 18650 lithium-ion battery has a long service life, the cycle life of normal use can reach more than 500 times, which is more than twice as long as ordinary batteries.

3. High safety performance. 18650 lithium-ion battery safety performance, non-explosive, non-combustible; non-toxic, non-polluting, certified by the RoHS trademark; a variety of safety features in one fell swoop, the number of cycles is greater than 500 times; high temperature performance is good, 65 degrees discharge efficiency of 100%. In order to prevent the battery short circuit phenomenon, 18650 lithium ion battery positive and negative poles are separated. So its possibility of short circuit phenomenon has been minimized. You can add a protection plate to prevent the battery from overcharging and overdischarging, which can also extend the service life of the battery.

4. high voltage. 18650 lithium-ion battery voltage is generally 3.6V, 3.8V and 4.2V, much higher than the nickel-cadmium and nickel-metal hydride batteries 1.2V voltage.
