High-Capacity 18650-15P Power Cylindrical Lithium Battery

The 18650‑15P is Changhong Sanjie’s flagship power‑type cell based on an NCM/NCA ternary chemistry. Its key selling points include a high capacity of 1,500 mAh, a stable 3.6 V nominal voltage, and an ultra‑low internal resistance of 11.5 mΩ, enabling efficient charge‑and‑discharge performance at 4 A charging and 20 A discharging. It is ideally suited for high‑rate discharge applications such as power tools and small drones. The cell employs high‑purity NCM ternary cathode material, paired with a high‑conductivity electrolyte and premium copper current collectors, laying a solid foundation for superior high‑rate performance. Production utilizes a proprietary fully automated line with end‑to‑end digital process control; each cell undergoes 100% full inspection and multiple rounds of rigorous safety testing to ensure consistent quality and stability. Its core advantage lies in the balanced combination of high rate capability and long cycle life—retaining over 80% of its initial capacity after 500 cycles—while also delivering excellent low‑temperature performance. Application areas extend to portable energy storage, medical devices, and more, with customizable PACK solutions available to help overseas customers develop highly competitive products.
