Chinese manufacturers are applying solid-state batteries to flying cars,
replacing liquid electrolytes to meet stricter airworthiness safety requirements
and potentially shortening the commercialization timeline. A flying car fitted
with a high‑energy solid‑state battery has completed a test flight across the
Qiongzhou Strait. The sector currently relies largely on high‑energy liquid
lithium cells; solid‑state technology is transitioning from lab toward mass
production, but improving cycle life to boost flight economics remains the main
constraint.
