What is an 18650 lithium battery and what is an 18650 lithium battery?

The 18650 lithium battery is a cylindrical lithium battery with a diameter of 18 mm, Battery recycling line a height of 65.0 mm and a rated voltage of 3.7 V. to meet the needs of more devices, the 18650 lithium battery pack came into being, in accordance with the 18650 lithium battery series-parallel assembly to achieve greater voltage and longer discharge time. 18650 lithium battery ternary material as a positive electrode battery, its Factor of safety than lithium cobalt acid battery, but the operating voltage is too low, so using a mobile phone (the cut-off voltage of the phone usually fluctuates up and down) can feel like a significant capacity shortage. At present, the former has been widely used in the sales market.

Difference between 18650 lithium battery and ternary lithium battery

1. Ternary lithium battery has large capacity. Its capacity is equivalent to 18,650 lithium-ion batteries, lithium battery welding machine and ternary lithium polymers can even run 10,000 marathons.

2.18650 lithium battery network life is very long, the longer its life, through the specially developed lithium-ion structure, the fully charged battery is about twice or more than that of ordinary users' charging system, so it can be said that the capacity is very large.

3.18650 Rechargeable lithium-ion battery has no memory. mounting machine This battery is likely not easy to charge and discharge the remaining charge before recharging, which makes it more convenient to use; Unlike nickel metal hydride batteries, nickel metal hydride batteries have the memory effect of discharge.

4.18650 lithium battery has small internal resistance and irreversible volume damage, which can greatly reduce the functional loss of rechargeable battery and improve the battery cycle times;

5.18650 the lithium-ion battery is of high safety and is unlikely to cause explosion or air pollution. The test results show that in most cases, the probability of common short circuit fault is reduced to the best case. Avoid overcharging or power outages.
