Recently, China’s solid-state battery technology has been applied to the field of flying cars, with solid electrolytes replacing traditional liquid electrolytes to meet the stringent safety and airworthiness requirements of such vehicles. A flying car equipped with a high-energy solid-state battery has successfully crossed the Qiongzhou Strait, demonstrating the stable performance of solid-state batteries in complex environments, including cross-sea flights.

Currently, solid-state batteries are at a critical juncture—transitioning from the laboratory to mass production—and the entire industry chain is on the cusp of an explosive growth phase. Su Qingpeng, CEO of Gaoyu Technology, a low‑altitude mobility startup incubated by GAC, has stated unequivocally that solid-state batteries are indispensable for the development of flying cars: they can simultaneously meet the dual demands of extended range and enhanced safety, while flying cars exhibit far greater tolerance for battery costs than conventional new‑energy vehicles.

On December 31, 2025, EHang’s EH216 series autonomous aerial vehicle, equipped with Xinjie Energy’s “Falcon” solid-state lithium-metal battery, took off from Nanhai Mingzhu Island in Haikou City, Hainan Province, and flew directly to Xuwen Port in Zhanjiang City, Guangdong Province, successfully crossing the Qiongzhou Strait. This marked the nation’s first-ever cross‑strait flight by an unmanned manned aerial vehicle, covering a distance of 22 kilometers in just 18 minutes and boosting travel efficiency by approximately 70% to 80% compared with conventional ferries.

Prior to EHang’s validation, XPeng Huitian’s dedicated battery for its “land‑aircraft” flying car has officially entered mass production. Manufactured by CALB, this specialized power battery boasts an energy density of 360 Wh/kg and a maximum discharge rate of 25C, having successfully passed a 15.2‑meter free‑fall test—meeting the stringent safety standards of the aviation sector while delivering automotive‑grade stability and cost‑effectiveness. CALB has also secured an exclusive supply agreement with XPeng Huitian for next‑generation models, with plans to launch a solid‑state battery variant in 2027 featuring an energy density exceeding 400 Wh/kg.

Xinwangda has officially announced the mass-production achievements of its aviation-grade solid-state batteries. Its two generations of semi-solid-state batteries—Gen1 (320 Wh/kg) and Gen2 (380 Wh/kg)—have already entered large-scale production. Notably, the Gen2 model, designed for manned eVTOL aircraft, offers a range of up to 320 kilometers, seamlessly integrating with platforms from leading manufacturers such as EHang, WoFei ChangKong, and Xpeng Huitian, and has successfully passed rigorous tests, including the nail penetration test.

Su Qingpeng, CEO of Gaoyu Technology, pointed out that the development of flying cars can be compared to that of electric vehicles a decade ago. 2027 will mark the inaugural year of commercialization for manned eVTOLs. By 2030, manned eVTOLs will have achieved commercial viability. The core value of solid-state batteries for flying cars lies in the following: while new-energy vehicles seek to drive down costs through mass production, flying cars aim to simultaneously address both long-range endurance and high safety—meaning that once small‑batch production becomes feasible, these batteries can be deployed, and as they are subsequently adopted at scale in automotive applications, they will further reduce operating costs and expand the commercial horizons of flying cars.

Notably, aviation‑grade solid‑state batteries produced by companies such as Xinwangda, Ganfeng Lithium, CATL, and Svolt Energy have already been widely integrated into the aircraft models of leading flying‑car manufacturers, including EHang, Volocopter, and XPeng Huitian. The year 2026 is widely regarded in the industry as the inaugural year for mass production of flying cars, and cross‑industry collaboration across the entire value chain—driving solid‑state batteries from the laboratory to full‑scale manufacturing—is accelerating. Meanwhile, the low‑altitude economy is projected to grow from RMB 1.5 trillion in 2025 to RMB 3.5 trillion by 2035.
