In today’s era of rapid technological advancement, lithium-ion batteries remain the core power source for a wide range of devices, making breakthroughs in performance and environmental adaptability increasingly crucial. In particular, extreme cold conditions pose a major challenge, as battery performance directly impacts reliable device operation. Leveraging decades of expertise in lithium battery technology, Far East Battery has broken through the limits of low-temperature performance, delivering high-power, long-endurance, and stable energy solutions for applications across defense, aerospace, low-altitude economy, robotics, polar expeditions, cold-zone emergency response, power and telecommunications, public safety, and medical electronics.

Backed by 16 years of R&D and manufacturing experience, Far East Battery continuously pushes the boundaries of innovation. By integrating high-energy-density silicon-based anodes, advanced conductive networks, and low-temperature high-conductivity electrolytes with mature large-scale production know-how, the company has achieved stable mass production of low-temperature lithium cells. The portfolio includes multiple high-adaptability product models within the 18650 series (2.6Ah, 3.3Ah, 3.5Ah, 3.8Ah) and the 21700 series (5.0Ah, 5.5Ah), all proven to perform reliably in environments as cold as -40℃.

Traditional lithium-ion batteries suffer severe performance degradation below -20℃, limiting their ability to support extreme-use cases such as drone flights at high altitudes in winter or robotic inspections in frigid environments. In contrast, Far East Battery’s ultra-low-temperature cells maintain stable operation across a wide temperature range of -40℃ to 60℃. At -40℃, they can achieve discharge efficiencies of over 70%. Notably, models such as the 18650-3.3Ah and 21700-5.0Ah are capable of small-rate discharge even at -50℃—truly breaking the industry’s low-temperature bottleneck and ensuring reliable power for devices in the harshest conditions.

Charging under cold conditions has long been a pain point, as conventional lithium-ion batteries cannot be charged reliably below 0℃. Far East Battery has overcome this challenge: its low-temperature series now supports stable charging at -10℃. This enables continuous power supply for applications such as outdoor surveillance systems in winter sunlight or sensor equipment deployed in cold regions.

With deep expertise in cylindrical cell technology, Far East Battery has established a comprehensive product matrix covering diverse capacities, temperature ranges, and application scenarios. Among these, the 21700-6.0Ah model stands out with its industry-leading high capacity, setting a new benchmark. This breakthrough in ultra-low-temperature cylindrical lithium batteries not only fills the gap in extreme cold power supply but also reinforces Far East Battery’s technological leadership and commitment to customer-centric innovation.

Looking ahead, Far East Battery will continue to focus on real-world application needs, delivering more reliable, efficient, and safe battery solutions—empowering devices to operate steadily under any temperature conditions.
