Internal Impedance of the Lithium-Ion Secondary Cells Used for Reimei Satellite after the Eleven Years Operation in Space

et al. 2017

View full text Add to dashboard Cite

The lithium-ion secondary batteries have been widely used for the space programs, today. Among them, REIMEI was one of the first satellites using lithium-ion secondary battery. In 2005, the satellite was launched, and injected into the low earth polar orbit. Eleven years has passed since the launch and over 60,000 cycles of charge and discharge was experienced in space. The lithium-ion secondary cell of the REIMEI battery was designed using spinel manganese oxide type material for the positive electrode, and the graphitized type carbon for the negative electrode. The cell case was made of aluminium laminated film and the structure was reinforced by the epoxy resin and aluminium housing. After the operation of eleven years, the cells still maintain the appropriate uniform balance and operative. In order to identify the internal condition of the battery/cell, we calculated the ac impedance by the pulse duration to the on-board battery.

Long Term Operability of Li-ion Battery under Micro-gravity Condition Demonstrated by the Satellite “REIMEI”

Lithium-ion secondary cells are widely used for the space applications, today. Among these applications, REIMEI, which was launched in 2005, was one of the first satellites using lithium-ion battery. The off-the-shelf type cells designed using spinel manganese oxide for the positive and the graphitized carbon for the negative electrode were used. The cell case was made of aluminum laminated film and the structure was reinforced by the aluminum case filled with epoxy resin. Today, ten years has passed, and the battery experienced 55,000 cycles for charge and discharge. The current distribution between two batteries almost coincided together even after the long term operation, which revealed the stable performance of the lithium-ion secondary cells under the microgravity in space.

Electron properties in inverted‐V structures and their vicinities based on Reimei observations

et al. 2014

This paper reports two event studies on characteristic pitch angle variations of inverted-V electrons observed by the Reimei satellite. At edges of the inverted-V structures, the electron pitch angles are collimated between 0• and 20• while the electric field of the potential distribution is commonly depicted perpendicular to the local magnetic field. As Reimei moved toward the center of the inverted-V regions, the electron pitch angles broadened up to ∼120• , and their energies rapidly increased and continuously changed to those of the energetic inverted-V component. At the higher latitudes of the inverted-V structure, diffuse electrons with the isotropic distribution were also observed. Estimations of the electron density and temperature indicate that the source region of the beam electrons is the topside ionosphere by comparison with those of the diffuse electrons and the energetic inverted-V electrons. For the auroral emissions, in the first event, some horizontal auroral motions were observed which may be accompanied by the horizontal drift motion of the whole structure of the parallel potential drop. This motion could supply electrons in the topside ionosphere into the potential structure, and then the beam electrons are continuously formed at the low altitudes. In the second event, on the other hand, at both edges of the auroral band, the auroral emissions did not expand while the beam electrons were observed. One of the probable reasons to produce the beam electrons is the inertial Alfvén waves although they are inconsistent with previous studies because the velocity dispersions were not observed.
