-40℃ low-temperature 18650-25L cylindrical lithium battery

The 18650-25L is a low‑temperature‑specific cell based on an NCM/NCA ternary chemistry. Its key selling points include compatibility with ultra‑low temperatures down to –40°C, a stable 3.6 V nominal voltage, an internal resistance of 13.5 mΩ, and charging at 2.5 A with discharging at 20 A. It is well suited for cold‑environment applications such as outdoor equipment and cold‑chain systems. The cell employs a low‑temperature‑resistant NCM ternary cathode material and a dedicated electrolyte, with an optimized cell architecture to ensure stable performance in subzero conditions. Production utilizes a low‑temperature‑adapted process, with rigorous quality control over electrode sheets and packaging; each unit undergoes 100% full inspection and passes low‑temperature discharge testing, guaranteeing more than 80% capacity retention even at –40°C. Its core advantages are exceptional low‑temperature performance, balanced power and cycle life—with a capacity retention of over 80% after 500 cycles—and a lightweight design weighing ≤48.0 g, making it ideal for outdoor devices. Applications span low‑temperature energy storage, outdoor power tools, cold‑chain monitoring equipment, and more, with customizable solutions available to meet the demands of overseas cold‑climate scenarios.
