| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The feasibility of the spacecraft power system using lithium-ion capacitors (LICs) as its energy storage source is discussed on the basis of a comparison with lithium-ion batteries (LIBs). Although the specific energy of LICs is rather lower than that of LIBs, the gap between LIBs and LICs in terms of the system mass can be significantly bridged by considering the LICs' outstanding life performance at deep depth of discharge (DoD), the reduced mass of photovoltaic array thanks to the introduction of a constant power charging scheme, etc. The mass comparison between the LIB- and LIC-based spacecraft power systems was performed for a 1 kW low-earth orbit load. In the case that the LIB-based system is operated at a relatively shallow DoD of less than 20% to achieve long cycle life, the LIC-based system with deep DoD of 60–80% can be comparable. The analysis indicated that the LIC can be an alternative energy storage source to the LIB that is operated with shallow DoD to achieve long cycle life, even from the power system mass view point. | |
