Simulation-led cell design with Avrion Battery Labs

Avrion Battery Labs and Ionworks replaced trial-and-error build loops with a physics-based model of the full eVTOL design space: +21% measured specific energy, two build loops instead of four, and energy density predicted within 5%.

What's running on your cyclers?

Actual runtime remaining plotted against state-of-charge reading for discharge powers from C/20 to 2C, every curve sitting below the ideal diagonal and high-power curves terminating at a positive state of charge

State of charge vs state of energy: why SoC overstates your runtime

One forward run of the same class of degradation fit: about 16 hours for the full-DFN coupled-aging model versus 34 seconds for the Ionworks SPMe pipeline
