50Ah Battery Cell eVTOL Ultra-High EC Nickel Cells

Core Overview

Leveraging Tsingshan Group’s resource advantages and aligning with the future trends of EV batteries, we have developed a high-energy-density battery cell (≥310 Wh/kg) specifically designed for low-altitude aircraft. This cell supports high-power discharge and delivers stable, continuous power tailored to the demands of flight.

Furthermore, we have established a strategic partnership with VERTAXI, an emerging leader in the eVTOL industry, to collaborate deeply on energy solutions. We proudly showcased our first high-energy-density cell for this sector at CIBF 2025. To further enhance safety and performance, we are actively advancing the integration of semi-solid and solid-state battery technologies.
