First, in terms of the application of the battery, there is a method of maintenance and alerting mechanical impact on aluminum-plastic composite film, top sealing edge (end cap edge), side edge edge, polar handle. 1, aluminum-plastic composite film outer packaging maintenance: tightly is damaged by sharp partial stabbed. To this end, it should often be sorted by the perimeter of the battery, stop the sharp part touch or touches the battery.

When you use it, you can wear your gloves, guard my fingernail scratching the surface of the cell. 2, the top edge and side edge cover maintenance: for the alert, the edge cover, damage to the sealing effect, should stop the bending top cover and side edge seal; together, the battery is planned to take relief insulation isolation The method is short-circuited by alert negative electrode and aluminum-plastic composite film. 3, polar handle maintenance: polymer lithium ion battery cell positive electrode extraction terminal is selected from the aluminum pole, and the negative electrode drawing terminal is selected from the nickel handle.

Because the pole is thin, bending should be stopped; together, the handle should be touched in the processing process, and the aluminum-plastic composite film is touched. 4, guard mechanical impact, such as fall, hit, bending battery and accidental battery. 5, stop metal, wire short circuit connection is negative.

Second, after a battery is done, the next step is to correctly combine with the outer casing and the battery core maintenance circuit module, making it a polymer battery, and the notes in this process are: 1, housing planning: (1), satisfaction The mechanical strength is detained by external force mechanical damage, (2), the electrical core device to the outer casing, the sharp edge angle of the guard housing; (3), alert aluminum-plastic composite film sandwich pure aluminum and external touch Short circuit. 2, non-planning battery maintenance circuit: contains the highest / minimum voltage scientific setting, overcurrent maintenance, battery cell combination should be charged with battery cells (single battery). 3, the positive aluminum pole handle is transferred by the nickel strip, and the electrical cell and the circuit board should be used to use ultrasonic welding or spot welding skills.

4, the battery is firmly positioned, the battery should be tightly fastened, not active, so that the entire lithium ion battery structure is in a fixed state.
