AbstractThe power sources which have long life performances are strongly desired for deep space explorations, advanced missions and so forth. Spacecraft ordinarily employ chemical batteries such as Ni-Cd, Ni-MH and Li-ion batteries as the power sources. Chemical batteries which store electricity by chemical reactions, however, have technical problems in the case of the very long term applications. Electronic double layer capacitors (EDLCs) which are prosperously developed in the civilian field are the electronic storage devices without chemical reaction. EDLCs have long life performances and high rate charge/discharge performances. In recent years, EDLCs have been applied for EVs (Electric Vehicles), UPSs (Uninterrupted Power Sources), assist power sources and so forth. In the space field, EDLCs were already applied to the exploration robot 'MINERVA' which was equipped to the interplanetary spacecraft 'HAYABUSA'. EDLCs received much attention to be applied to the very long term missions such as Space Solar Power Systems (SSPS). We tested the basic performance of EDLCs, and simulated the satellite operations using EDLCs. The capacity retention ratios of EDLCs were remarkable higher than that of Li-ion cells. Especially the capacity retention ratio of the cell without the charge at constant voltage (CV) was better than that of the cells charged at CV. It was confirmed that the length of the CV charge time influenced the degradation of the cells. The differences of the degradation trends of the cells were not observed in spite of the simulation tests for the satellites were conducted by various values of DoD (Depth of Discharge). Through these experiments, it was conjectured that the EDLCs were possible to apply for the power sources of spacecraft.
