Popis: | The specific advantages of lithium-ion technology in energy density and working voltage offer the possibility of huge reductions in battery mass, and hence contribute to lower launch costs and enable missions that have critical weight and/or volume margins. To facilitate the applications of lithium-ion battery in a spacecraft, we began conducting the long-term evaluation on 10-100 Ah-class lithium-ion cells by simulating satellite's operation in 1998. In this paper, we provide a review of the latest cycle-life test results of these large-capacity lithium-ion cells. Thus far, for some of these cells, we have verified impressive life performance exceeding 30,000 cycles in a low-Earth-orbit (LEO) simulation mode and 1,800 cycles in a geosynchronous-Earth-Orbit (GEO) simulation mode. These results respectively correspond to about 5- and 20-year LEO and GEO satellite operations, indicating good applicability of lithium-ion cells as power storage devices in a satellite. Since the electrode material is an important factor to affect the charge-discharge behavior of a lithium-ion cell, we also compared the cycling performance of lithium-ion cells with different electrode materials. 資料番号: AA0049500055 レポート番号: JAXA-SP-06-006 |
