AbstractHigh energy density Li-ion battery is expected for next generation satellites and the other space usage. Japan Storage Battery Co., Ltd. (JSB) has developed two types of large capacity Li-ion cells through cooperation with Mitsubishi Electric Corporation (MELCO). One is satellite type (50, 100 and 175 Ah) for long life applications and the other is rocket type (55, 110 and 190 Ah) for high energy applications. The energy density of the cells are 136 Wh/kg to 164 Wh/kg. They correspond to the 1.5 to 2.0 times of Ni-H2 cell. The cells have completely sealed structure achieved with ceramic hermetic seal in order to endure the space environment. JSB has confirmed that the cells performance satisfies space application requirements. Furthermore, JSB has started developing small size Li-ion cell (10 Ah) for small satellites. SERVIS-1 that equipped with Li-ion battery system (cells: by JSB, battery: by MELCO) was launched in October 2003. The Li-ion battery consists of eleven Li-ion cells (50 Ah) in series. SERVIS-1 has been operated smoothly on orbit. The results more than two years in total will be obtained on orbit in SERVIS-1. It is scheduled that the Li-ion cells of 50 to 175 Ah by JSB are installed in some satellites that will be launched by 2007.
