What is the significance of sticker machine for battery cell

Insulation protection:

Prevent short circuit: The positive and negative poles of the battery cell need good insulation, otherwise a short circuit may be caused by accidental contact. The insulating paper (such as barley paper, etc.) attached by the sticker machine can effectively isolate the positive and negative poles, avoid direct contact between the positive and negative poles or indirect contact caused by foreign objects, dust, etc., thereby reducing the risk of short circuit. For example, in electronic devices used in daily life, if the battery cell is short-circuited, the device may be instantly powered off or even damaged; in the power battery of electric vehicles, short circuits may cause serious safety accidents, and insulating stickers can effectively prevent such situations.

Avoid leakage: Good insulation can prevent current from leaking in unexpected paths, ensure that the power of the battery cell can be transmitted and used according to the designed circuit path, improve the utilization efficiency of power, and also reduce the damage to other parts of the equipment caused by leakage.

Mechanical protection:

Buffering effect: During the production, transportation and use of the battery cell, it may be impacted or vibrated by various external forces. Insulation stickers can play a certain buffering role, absorb and disperse these external forces, reduce damage to the internal structure of the battery, protect the key components of the battery such as electrodes and diaphragms from damage, and maintain the stability of the performance of the battery. For example, when a mobile phone accidentally falls, the impact force on the internal battery will be partially buffered by the sticker, reducing the possibility of damage to the battery.

Prevent wear and tear: Insulation stickers can prevent direct friction between the battery and external objects, and reduce physical damage such as wear and scratches on the surface of the battery caused by friction. Long-term wear and tear may damage the outer shell of the battery, thereby affecting the insulation performance and overall safety of the battery.

Other protective effects:

Dust and moisture-proof: stickers can prevent dust, moisture, etc. from entering the battery to a certain extent. If dust enters the battery, it may affect its performance; if moisture enters, it may cause a short circuit or other chemical reaction, damaging the battery. In some application scenarios with high environmental requirements, such as outdoor electronic equipment and underwater equipment, the dust and moisture-proof effect of stickers is particularly important.

Easy to identify and manage: By printing or marking relevant information on the sticker, such as the cell model, specification, production date, batch, etc., the cells can be easily identified, classified and managed, which helps to improve production efficiency and the accuracy of quality traceability. For example, on a large-scale battery production line, different batches of cells can be quickly and accurately identified, which facilitates quality control and problem tracing.
