Zhi Tong Cai Jing·2026-01-13 06:22Core Viewpoint - Solid-state batteries are highly compatible with satellite applications due to their lack of liquid electrolytes, low gas evolution risk, radiation resistance, and temperature tolerance, making them a promising investment direction for the industry [1][6]. Group 1: Performance and Compatibility - Solid-state batteries exhibit superior performance characteristics suitable for satellite environments, where traditional liquid lithium-ion batteries face significant risks such as electrolyte evaporation and thermal runaway [2]. - The inherent safety of solid-state electrolytes, which do not contain flammable or volatile components, enhances their stability in vacuum conditions, making them more suitable for long-term space missions [2]. Group 2: Industry Development and Testing - Solid-state batteries have progressed from laboratory validation to engineering and in-orbit verification stages in the satellite sector, with successful tests conducted by JAXA and Hitachi Shipbuilding [4]. - A solid-state lithium-ion battery was launched to the International Space Station in February 2022, demonstrating successful charge and discharge operations over 434 days with no significant capacity degradation [4]. Group 3: Policy Support and Market Outlook - The solid-state battery industry is receiving significant policy support, with multiple initiatives introduced since 2025 to promote its development [5]. - As pilot tests advance, the mass production timeline for solid-state batteries is expected to accelerate, indicating a strong growth trajectory for this technology [5]. Group 4: Investment Recommendations - Companies such as CATL, EVE Energy, and others are recommended for investment due to their involvement in solid-state battery technology, which is anticipated to see increased penetration in the aerospace sector [6].
