AbstractLarge capacity Li-ion cells with 50-175 Ah had been developed to meet the requirements of space environment. Calendar and cycle life characteristics of the Space Li-ion cells have been evaluated under various test conditions with wide range of temperature (0 deg. C - 60 deg. C), depth of discharge (3 % - 80 % DOD), and state of charge (0 % - 100 % SOC). The test was started in June 1999, and the data have been accumulated for around seven years. From these results, based on capacity loss mechanism, we have established calendar and cycle capacity loss estimation method for the Li-ion cells. In this presentation, we will explain capacity loss mechanism, life estimation method and charge-discharge performance at high temperature for the Lithium-Ion Cells.
