Beyond Standards - In Depth Analysis of The Excellent Performance And Safety Assurance of Our Cylindrical Batteries

There are many brands of cylindrical batteries on the market, but the quality varies greatly. This article will reveal how our products surpass industry standards in core materials, manufacturing processes, and safety design, in addition to standard specifications.

Choosing a cylindrical battery is not just about choosing a set of model numbers (such as 18650 or 21700), but also about choosing the technical expertise and quality commitment behind it. We are committed to achieving perfection in every detail, ensuring that every battery leaving the factory represents the highest quality.

1. Innovation in core materials:

Positive electrode material: We use high-capacity, high-voltage nickel cobalt manganese (NCM) or lithium iron phosphate (LiFePO4) material systems, and achieve the best balance between energy density, cycle life, and thermal stability through precise chemical ratios and nanoscale synthesis processes.

Negative electrode material: Using high rate, long-life graphite or silicon carbon composite materials significantly improves the charging speed and charge discharge cycle times of the battery.

Electrolyte and separator: The customized functional electrolyte formula and high-strength separator using ceramic coating technology jointly build a safety defense line inside the battery, effectively preventing short circuits and thermal runaway.

2. Precise manufacturing process:

Our fully automated production line operates in a Class 10000 dust-free workshop, ensuring the consistency and integrity of the internal structure of the battery cells through cutting-edge processes such as laser welding and automatic winding. Each process is equipped with an online detection system to eliminate defective products in real time, ensuring high consistency between product batches.

3. Multi level security system:

Safety is our top priority. Our battery has multiple built-in protection mechanisms:

Physical safety valve: When the internal pressure rises abnormally, the safety valve will automatically open to release pressure and prevent explosion.

PTC (Positive Temperature Coefficient) component: When the temperature rises due to excessive current, the PTC resistor will increase sharply, effectively limiting the current and providing overcurrent protection.

CID (Current Interruption Device): In extreme abnormal situations, CID will permanently cut off the current path, providing ultimate protection for the battery.

4. Strict testing and certification:

Each batch of batteries must undergo dozens of rigorous tests, including cycle life testing, high and low temperature performance testing, and abuse testing such as needle punching/squeezing. Our products comply with international safety certifications such as UL, CE, RoHS, etc., meeting the entry requirements of the global market.

Conclusion:

Our cylindrical 3.7V lithium-ion battery is the culmination of cutting-edge materials science, precision manufacturing technology, and rigorous safety concepts. We not only provide batteries, but also offer a commitment to ensure that your products are worry free.
