As the core component of energy storage systems, cell performance is directly linked to the safety of users' lives and property. Leveraging independently developed cylindrical cell technology, Far East Battery has built a full range of high-capacity, high-rate, and mid-rate cylindrical cells — all now certified under China's Compulsory Certification (CCC) system.

Technological Innovation Builds a Solid Safety Foundation

Backed by 16 years of cylindrical battery R&D, Far East Battery has launched a complete portfolio of high-safety, high-energy-density cylindrical cells, tackling safety challenges through continuous innovation.

The cells incorporate dual protection mechanisms:

• CID (Current Interrupt Device) for overcurrent disconnection

• VENT for directional pressure relief

They also employ cutting-edge materials such as high-temperature-resistant ceramic-coated separators and high-stability electrolyte additives, enabling the 21700 series to reach a capacity breakthrough of 6000mAh — all while ensuring stable performance under extreme conditions. These technologies build safety into the product from the ground up.

Strict Quality Control Establishes a Safety Barrier

Safety is not only designed — it is meticulously manufactured. Understanding this, Far East Battery has invested hundreds of millions of RMB to build fully imported, high-speed automated production lines, pushing the limits of quality control precision.

The production environment is rigorously managed:

• Cleanrooms are maintained at Class 10,000 (no more than 10,000 particles ≥0.5μm per m³ of air)

• Key production areas achieve Class 1,000 cleanliness standards

• Constant temperature and humidity control, along with high-efficiency air filtration, effectively eliminate potential contamination from dust and moisture

Process monitoring is equally uncompromising:

• Over 300 high-precision monitoring points track every stage — from raw material feeding to final cell formation

• Parameters such as coating thickness, winding tension, electrolyte injection accuracy, and welding strength are monitored in real time, leaving no room for error

This "zero tolerance" quality control system ensures outstanding performance and high consistency for every Far East cylindrical cell, eliminating potential safety risks at their source.

Authoritative Certifications Safeguard the Safety Baseline

With years of deep expertise in cylindrical cell development, Far East Battery's products not only meet China’s mandatory CCC standards, but have also earned multiple internationally recognized safety certifications, including:

• UL (North America)

• IEC (International Electrotechnical Commission)

• UN38.3 (air transport safety standard)

These are not just pieces of paper — they represent Far East cells’ ability to withstand short circuits, crushing, overcharging, over-discharging, high temperatures, drops, and dozens of other extreme safety tests. Each certificate is forged in the “fire” of rigorous third-party evaluations, proving the real-world reliability of Far East cells.

Behind every certificate lies the company’s quiet but firm promise: “Safety knows no borders.”

“Core” Commitment to Safety Starts at the Cell

In the energy storage industry, cell safety is the cornerstone of user protection.
Through technological innovation and strict quality control, Far East Battery’s cylindrical cells have earned multiple authoritative certifications, building a strong foundation for global safety.

With safety at its core, Far East Battery sets a new benchmark for the industry — and delivers trusted protection to customers worldwide.
