Japan's asteroid explorer Hayabusa (MUSES-C: Asteroid Sample-return Spacecraft), which was launched in May 2003 and is on its way to the Earth hopefully with some samples collected at the asteroid ITOKAWA, is the world's first spacecraft powered by a Li-ion battery, from The Furukawa Battery Corp. The battery consists of 11 prismatic 13.2 Ah battery cells connected in series and has a specific energy of more than 85 Wh/kg. The bus voltage varies from 32.5 to 47.5 V during the battery mode according to the state of charge of the battery. On the basis of the battery technology for 'Hayabusa', we started developing the Li-ion battery for the Venus Climate Orbiter 'PLANET-C' in 2002. Since a further improvement in the mass advantage was requested for the mission, the enlargement of the capacity and the increase of the energy density were examined through the surface modification of an anode active material and the improvement of the separator. As a result, a 23.5 Ah class prismatic Li-ion battery of high energy density was made for trial purposes by 2004. We performed a life test keeping the battery fully charged under the float charge condition, and found that their aged deterioration was reduced by half from the battery for 'Hayabusa'. This aged deterioration test started in 2005 followed by a float charge test and a cycle life test. We also performed a test that simulated the planned charge and discharge operations for the 'PLANET-C' mission. The results allowed us to confirm that the capacity deterioration simulation used in designing the battery was valid. Currently we are investigating the most appropriate operational pattern of the battery that controls the state of charge according to the length of the eclipses keeping the deterioration minimum.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0063965003","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙航空研究開発機構宇宙科学研究本部"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA/ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"古河電池"},{"subitem_text_value":"古河電池"},{"subitem_text_value":"古河電池"},{"subitem_text_value":"古河電池"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"},{"subitem_text_value":"宇宙航空研究開発機構 宇宙科学研究本部"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Furukawa Battery Co.
