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.(金十数据)
