AbstractLarge lithium ion cells in capacity range of 50 to 190 Ah for space applications have been developed and tested. It was evaluated for both calendar life and cycle life characteristics to confirm life performance for satellite applications. From these results, we established a simple formula to calculate cell capacity fade and impedance increase. In addition, we have been conducting various kind of life simulation tests on other cells from different manufacturing lots and confirmed that the cell satisfied general life requirements of these applications. We have verified the model by comparing calculated capacity fade estimates with the simulated life tests. Since our calculated life estimates match the experimental data with a high degree of precision, we feel this demonstrates the validity of our life model.
