Craftsmanship - How Do We Ensure Excellent Quality for Every Cylindrical 3.7V Battery

A high-performance, safe and reliable cylindrical 3.7V battery was not obtained by chance. It is the result of the pursuit of ultimate quality that runs through every link from raw materials to finished products.

Main text:

Our commitment is that every battery delivered carries consistent high performance and absolute safety assurance. This commitment is achieved through the following core manufacturing and quality control systems:

Source control, carefully selected materials: Quality begins at the source. We strictly screen the top global suppliers for positive electrode materials, negative electrode materials, separators, and electrolytes. Only raw materials that meet our strict standards can enter the production line, ensuring the high energy density and long lifespan potential of batteries from the foundation.

Fully automated and intelligent production line: We have invested in the construction of a highly automated production line. From electrode coating and winding to liquid injection and sealing, the vast majority of processes are completed by precision robots. This not only greatly improves production efficiency, but more importantly, minimizes human error to ensure extremely high consistency and reliability of the product.

Chemical capacity division and "battery archives": These are the most critical "activation" and screening steps in battery manufacturing. Each battery will undergo its first charge (formation) and capacity test (capacity division) on a dedicated device. We record the initial voltage, internal resistance, capacity, and other key data of each battery, which is equivalent to establishing a unique "identity file" for it, ensuring that batteries with matching performance parameters can be used in combination.

Multiple safety checks: Safety is our lifeline. In addition to the safety valve and diaphragm design inside the battery cell, the finished battery also needs to undergo a series of rigorous safety tests, including but not limited to:

Overcharge/Overdischarge Test: Simulating extreme situations of circuit failure.

Short circuit test: to test the reaction of the battery in the event of an unexpected short circuit.

Thermal shock test: Verify the stability of the battery under severe temperature changes.

Acupuncture test: One of the most rigorous safety tests to test the thermal runaway control ability of batteries in the event of internal short circuits.

Continuous performance and lifespan testing: We have a dedicated laboratory to conduct continuous cycle lifespan testing, high and low temperature performance testing, and long-term storage testing on bulk products, continuously verifying and optimizing our product design.

Conclusion: Our dedication to quality is not only to meet specifications, but also to win your long-term trust. Choosing our cylindrical 3.7V lithium battery is a commitment to energy that is jointly safeguarded by cutting-edge technology, rigorous craftsmanship, and an infinite sense of responsibility. Let's join hands and inject the strongest and most reliable source of power into your innovative products.
