Energy Storage Technology Study for Future NASA Space Science Missions

摘要

The goals of the study were to 1) assess the potential ofadvanced energy storage technologies to enable and/orenhance next decade NASA Space Science missions,and 2) define roadmaps for developing advancedenergy storage technologies that will enable or enhancefuture NASA space science missions.The following technology advances were identifiedbased on the mission performance improvements dueto energy storage technology.A) Primary energy storage systems with improvedspecific energy and extended temperature range. Lowtemperature operation is important for missions toMars, small bodies and the outer solar system. Primarystorage systems that could operate at 460°C are ofinterest in Venus exploration and Sun missions.B) Rechargeable energy storage systems with highspecific energy (200Wh/kg) that can operate for 15years and 50,000 cycles. Lowering the operatingtemperature to –80C would provide advantages forseveral missions. Cycle life is important for somemissions. However the need is not low-T capability andimproved cycle life; just one or the other.
