EHang(US:EH) DT新材料·2026-01-07 16:15Core Viewpoint - The article highlights the successful test flight of the EHang 216 eVTOL powered by the Falcon solid-state lithium metal battery, marking a significant milestone in the application of advanced battery technology in aviation [2][4]. Group 1: Battery Technology - The Falcon solid-state lithium metal battery has an energy density exceeding 480 Wh/kg, which is 1.5 to 2 times higher than existing mainstream aviation batteries [4]. - The battery utilizes HICORE solid-state electrolyte technology and interface-oriented TIE technology to enhance ionic conductivity while reducing leakage and combustion risks [4]. - The design of the lithium metal anode achieves a volumetric energy density of 1200 Wh/L, and the battery has passed various safety tests, ensuring reliability for cross-sea flights [4]. Group 2: Project Development - On December 29, 2025, the first batch of solid-state cylindrical batteries from a 10 GWh production project by the company was launched in Hangzhou, with an initial capacity of 2 GWh aimed at consumer electronics [5]. - The second phase of the project plans to add 8 GWh of capacity, targeting eVTOLs, humanoid robots, and electric vehicles [5]. - A new project in Zhongshan, Guangdong, with a total investment of 160 million yuan, aims to establish a production line for 0.25 GWh of lithium metal solid-state batteries by 2026 [5]. Group 3: Collaboration and Future Plans - The company began collaborating with EHang in early 2023 to develop the eVTOL power system, achieving a record flight duration of 48 minutes and 10 seconds during their first test flight in November 2024 [4]. - The partnership has focused on optimizing battery output characteristics and thermal control for challenging maritime conditions, ensuring temperature increases do not exceed 18°C during flights [4]. - The company plans to mass-produce the next-generation "Falcon 2.0" solid-state battery by the end of 2026, with an expected energy density exceeding 500 Wh/kg [5].
