SBIR 95-1 SOLICITATION
PROJECT SUMMARY
Proposal Number:
Project Title:
LITHIUM-ION BATTERIES FOR MICROSPACECRAFTS
Technical Abstract:
It is desirable that rechargeable batteries for microspacecrafts
have a specific energy approaching 200 Wh/Kg, an energy density
greater than 300 Wh/l, and a cycle life exceeding 1000 cycles.
To this end, we propose to develop a Li-ion battery based on
graphite as the anode and lithiated manganese oxide (LiMn2O4) as
the cathode. The energy density and cycle life of this battery
can be significantly improved from the present values and made
to approach those cited above the mitigating or compensating for
the parasitic reactions involving the electrolyte at the
graphite electrode. The Phase I effort is aimed at
demonstrating a graphite/LiMn2O4 battery having significantly
higher energy by using improved electrode materials prepared as
proposed here. The graphite/LiMn2O4 battery uses
environmentally friendly materials and, therefore, would be of
considerable interest for consumer applications.
Potential Commercial Applications:
By virtue of its high energy density the lithium-ion battery
will be an ideal power source for use in the microspacecraft
technology. It would also find use in NASA's various other
space applications such as the Mars Rover, planetary space
probes and geosynchronous spacecraft where space availability is
at a premium. are in consumer
products such as portable telephones, laptop computers,
camcorders, and hand-held tools.
