Some advantages of 18650 lithium ion battery

1. The capacity of 18650 lithium ion battery with large capacity is generally between 1200mah~3600mah, while the general battery capacity is only about 800. If 18650 lithium ion batteries are combined to form a 18650 lithium ion battery pack, the 18650 lithium ion battery pack is casual It can break through 5000mah. 2. Long life The 18650 lithium ion battery has a long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries. 3. High safety performance 18650 lithium ion battery has high safety performance, non-explosive, non-combustible; non-toxic, non-polluting, and has passed RoHS trademark certification; various safety performances can be achieved in one go, the number of cycles is greater than 500; high temperature resistance performance, 65 degrees conditions The discharge efficiency reaches 100%. In order to prevent battery short-circuit phenomenon, the positive and negative electrodes of the 18650 lithium ion battery are separated. Therefore, the short-circuit phenomenon may have been reduced to the extreme. A protection board can be installed to prevent overcharge and overdischarge of the battery, which can also extend the service life of the battery. 4. High voltage The voltage of 18650 lithium ion batteries is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-hydrogen batteries. Lithium-ion batteries* were used in pacemakers early. The advantages of lithium-ion batteries, such as extremely low self-discharge rate and gentle discharge voltage, enable pacemakers implanted in the human body to operate for a long time without recharging. Lithium-ion batteries generally have a nominal voltage higher than 3.0 volts and are more suitable for integrated circuit power supplies. The general quality standard for lithium-ion batteries is at least 300 charge and discharge cycles. Generally speaking, the capacity is only 90% of the original capacity after 10 times of charging and discharging. After more than 300 times, the capacity will become about 70% of the original capacity and then gradually decrease.
