Japan Aerospace Exploration Agency (JAXA) developed piggyback satellite named INDEX. We applied lithium-ion secondary battery based on pouch cells for the satellite. The cell is designed using manganese oxide for the positive electrode and graphite carbon for the negative. The electrolyte for the lithium-ion cell is dissolved by organic solvent. Due to this configuration of the cell, the cell expands under the vacuum conditions. Since the expansion increases the DC impedance of the cell, we observed the degradation of the performance under vacuum conditions. In order to prepare the battery which is tolerant against the vacuum environment, the pouch cells were potted with resin and reinforced by the aluminum housing. More than 3,300 cycles of the charge/discharge performance was confirmed. We also tested the tolerance against the radiation using bare cells, and observed no degradation of capacity. Through these experiments, we confirmed the appropriate performance of the lithium-ion pouch cells for the operations of INDEX.
