Abstract :
Much of the mass of a battery is comprised of nonreactive materials. In an Ni-H2 battery, this includes the pressures vessel and 50% of the positive electrode PowerCoreTM reconfigures the battery materials to serve as a structural sandwich panel. The effective specific energy of the new device can exceed 100 Wh/kg. PowerCoreTM is intended to handle power demands of low Earth orbiting communications satellites such as IRIDIUM(R). This paper describes the concept and development progress
