Since they were first introduced in the early 1990's, lithium ion batteries have enjoyed unprecedented growth and success in the consumer marketplace. Combining excellent performance with affordability, they have become the product of choice for portable computers and cellular phones. Building on the same energy and life cycle attributes, which marked their consumer market success, but adding new high power storage capability, lithium ion technology is now poised to play a similar role in the transportation sector. With major programs in various aspects of electric and hybrid electric vehicles, Saft has developed a family of battery products which address the power and energy storage where light weight, long life, and excellent energy or power storage capabilities are needed. Significant progress in the packaging and control of high power, yet compact, batteries has been accomplished for a variety of vehicle applications.

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.
