The 18650 type lithium battery is a commonly used lithium battery in electronic products. It is often used as a battery cell in the battery of the notebook computer. 's battery.

Advantage

The 18650 lithium battery has high safety performance. In order to prevent the short circuit of the battery, the positive and negative electrodes of the 18650 lithium battery are separated, so the possibility of short circuit has been reduced to the extreme. It also extends battery life.

Shortcoming

18650 lithium battery production requires protection circuits to prevent the battery from being overcharged and causing discharge. Of course, this is necessary for lithium batteries, which is also a common drawback of lithium batteries, because the materials used in lithium batteries are basically lithium cobalt oxide materials, and lithium batteries made of lithium cobalt oxide materials cannot be discharged at large currents, and their safety poor.
