鈼?/strong> Battery Pack Materials
1).18650 lithium ion battery cell
Diameter: 18 + / - 0.2 mm
Length: 65 + / - 2.0 mm
Shape: Cylindrical
Nominal voltage:3.7V/3.2V
Limited charging voltage:4.2V/3.6V
Capacity: Customized
鈪? High capacity
The capacity of 18650 battery pack is generally between 1200 mAh and 3400 mAh and much higher than the capacity of the normal battery.,
鈪?Long life
The normal use cycle life of 18650 battery pack can reach more than 500 times (IFR: 2000 times),which is more than twice as long as the ordinary battery.
鈪? No memory effect
18650 battery pack can be charged and discharged at any time.
鈪? High safety:
18650 lithium ion battery has high safety performance, PTC resistance protection and explosion protection.
C).Charging and discharging process
18650 battery pack is made up of electrolyte, positive and electrodes.The positive electrode releases some ions when the battery is charging. These ions move from the positive electrode to the negative electrode through the electrolyte. After reaching the graphite electrode, it remains there. These ions should move back to the positive electrode during the discharging process. These ions travel through the electrolyte once again, but this time the battery is giving out its power. The movement of the ions from the negative electrode to the positive electrode is what powers the battery.
2).PCM, electronic wire and nickel strips:
PCM (Protection circuit Module): Prevent 18650 lithium ion battery overcharge, over discharge, over current, short circuit.
Wire: High temperature resistance, not easy aging, waterproof.
Nickel strips: Smooth and clean surface, combination of 18650 lithium ion battery through series and parallel connection.
鈼?/strong> Battery Pack
All production materials are ready. According to your detailed requirements, we will make the samples of 18650 battery pack through parallel or series assembly.
