Sou Hu Cai Jing·2026-03-10 02:03Core Viewpoint - The low-altitude economy has been highlighted in the government work report for three consecutive years, indicating its growing importance as a new pillar industry in China, with a focus on developing high-energy, high-power batteries for flying vehicles [3][4]. Group 1: Industry Development - The low-altitude economy market in China is projected to reach a scale of 1.5 trillion yuan by 2025 and 3.5 trillion yuan by 2035, showcasing significant growth potential [3]. - The electric vertical takeoff and landing (eVTOL) aircraft and large drones are central to the low-altitude flight sector, requiring advanced power systems that exceed the energy density and reliability demands of electric vehicles [3][4]. Group 2: Challenges and Recommendations - Current eVTOL battery energy densities have surpassed 300 Wh/kg, but to achieve economic operation in urban air mobility, advancements to 400-500 Wh/kg or higher are necessary [4]. - The existing battery standards do not fully address the extreme conditions faced by aircraft, such as thunderstorms and high-altitude low temperatures [4]. - Recommendations include establishing a national special plan for battery development in low-altitude flight, creating a major national technology project for advanced power systems, and developing industry standards for aircraft-specific batteries [5].
