Solid-State EV Batteries: What Donut Lab’s Test Really Proves

At CES 2026, Donut Lab unveiled a production-ready solid-state EV battery with ultra-fast charging validated in lab tests. Despite impressive technical results, industrial scalability, long-term state of health, and pack-level reliability remain unproven. For the EV economy, economic value comes from predictable, certifiable battery health, not peak cell performance.

What is the gap between WLTP range and real-world range?

Battery range is the distance an EV can travel on a full charge, affected by driving, load, temperature, and battery health. Ratings use standards like WLTP (Europe) and Environmental Protection Agency (US), with EPA usually lower than WLTP.

How to define battery State-of-Health

State-of-Health (SoH) measures a battery’s remaining usable energy compared to when new, and although the EU regulation uses the standardized State of Certified Energy (SoCE), in practice SoH effectively reflects the same concept of energy-related degradation.
