Shanghai Institute of Space Power-Sources is a space power system research institute under the Eighth Academy of China Aerospace Science and Technology Corporation (CASC). It is China's leading integrator of space power systems, primarily engaged in the research, design, manufacturing, and testing of power systems and key equipment for applications including manned spaceflight, lunar exploration, BeiDou navigation, Earth-observation satellites, launch vehicles, and space science missions.
Aligned with national medium- and long-term development plans, the Institute leverages China's first State Key Laboratory of Space Power-Sources as its core strategic asset. It also hosts four national-level R&D platforms and seven provincial/ministerial-level R&D centers, dedicated to advancing the three major technological disciplines of electronic power, physical power, and chemical power. Together, these form an integrated technology innovation platform that combines fundamental research, original innovation, and engineering implementation.
Built upon a solid foundation of aerospace technology and industrial resources, the Institute has for many years been deeply engaged in new energy sectors, accumulating strong technical capabilities and extensive experience. Guided by national strategic directions, it precisely targets emerging industries and future-oriented industrial sectors, focusing on nurturing specialized and sophisticated enterprises. The Institute is strategically expanding into commercial aerospace, low-altitude economy, hydrogen energy, and other frontier fields, and currently oversees four industrial companies. Through deep integration of industry, academia, and research, and driven by continuous innovation, SISP is advancing the high-quality development of aerospace technology applications.
Committed to excellence in talent development, SISP attracts top talent from across the nation. Leveraging the Ministry of Science and Technology's "National Innovation Talent Training Demonstration Base," the Institute has cultivated a dynamic, innovative, and enterprising aerospace workforce, consisting of national and provincial-level experts, elite doctoral teams, and core technical professionals. This team provides a solid guarantee of ideological commitment, technical excellence, and professional integrity for major national aerospace missions.
