Customization and processing
customization process
Preliminary negotiation
Preliminary determination of cooperation intention
Clear needs
Clear customer needs of the battery model and processing methods, etc.
Sample development
Customize and send samples according to requirements, wait for customer feedback, and adjust until the samples are confirmed
Order production
Determine the good sample, sign the contract, formal mass production, on schedule delivery
Customized completed
End of the order, look forward to cooperation again
solder sheet
Through resistance welding or ultrasonic welding, metal connectors such as nickel sheets are fixed between the electrode and the shell inside the battery to form a rigid support structure. This method can effectively resist the impact of external forces such as vibration and drop, and avoid the problem of power failure caused by poor electrode contact. It is common in complex scenarios such as vehicle equipment and industrial sensors. After welding, a tensile test is required to ensure that the mechanical strength meets the standard.
Protection circuit
The miniature PCB protection board is welded in series on the negative electrode of the battery, and the overcharge, over discharge and short circuit protection circuits are integrated. The current state is monitored in real time by temperature sensor and MOS tube. The circuit is automatically cut off when abnormal, and the fault response time is less than 50 ms. It is mostly used in Bluetooth headphones, medical equipment and other fields with high safety requirements.
Welding wire processing
Using high-precision spot welding or laser welding technology, conductive materials such as nickel-plated steel strips are firmly connected to the positive and negative poles of the battery and extended to the external wire interface. This method can ensure the stable transmission of micro-current, and is suitable for micro-devices ( such as hearing aids, smart watches ) that are sensitive to voltage fluctuations. During the welding process, the temperature and pressure should be accurately controlled to avoid damage to the internal structure of the cell, and the oxidation resistance treatment should be used to improve the durability of the interface.
