50Ah Battery Cell eVTOL Ultra-High EC Nickel Cells

Key Characteristics:

Cell Chemistry：High-nickel NCM

Leveraging Tsingshan Group’s resource advantages and aligning with the future development trends of EV batteries, we have developed a high-energy-density battery cell (≥310Wh/kg) specifically designed for low-altitude aircraft. This cell supports high-power discharge and delivers stable, continuous power tailored to the demands of low-altitude flight. Additionally, we have established a strategic partnership with VERTAXI an emerging leader in the low-altitude aircraft industry, enabling deep collaboration on eVTOL energy solutions. We proudly showcased the first high-energy-density battery cell for this sector at CIBF2025. Furthermore, we are advancing the integration of semi-solid and solid-state battery technologies to this field to further enhance battery safety and performance.
