Predictive Testing for GEO and LEO Lithium Ion Space Cells

Very little published data exist for the lithium ion chemistry showing that it will meet the rigors of GEO or LEO satellites. This paper reveals that the graphite/LiNiO₂ chemistry has achieved 133,000 discharges at 30% DOD in 18650 cells. Full scale 40 Ah cell data predicts ∼ 4000 cycles for 60% DOD and above 100,000 cycles for 20 and 30% DOD.
