新型燃料电池原型装置获验证

Group 1 - A breakthrough technology for a new type of battery prototype has been developed, achieving an energy density over three times that of current lithium-ion batteries used in electric vehicles [1] - The new battery is a fuel cell that regenerates energy through fuel supplementation, using liquid sodium metal as a low-cost and abundant material [1][2] - The technology has significant potential for the aviation industry, where increased energy density could enable large-scale practical electric flight [1][3] Group 2 - Current electric aviation requires an energy density of approximately 1000 watt-hours per kilogram, while existing lithium-ion batteries only reach about 300 watt-hours per kilogram [2] - The experimental prototypes have demonstrated an energy density close to 1700 watt-hours per kilogram for a single battery stack, with the entire system averaging over 1000 watt-hours per kilogram [2] - The system could be adapted for various transportation sectors, including maritime and rail, contributing to deep decarbonization in the industry [3]
