Abstract:

The anticipated result of Phase I is the development of an electrolyte for the lithium/silver-vanadium-oxide
(Li/SVO) system that would provide cell performance at -40 C as demanded by Emergency
Locator Transmitters (ELTs) and Emergency Position Indicating Radio Beacons (EPIRBs).
The Li/SVO chemistry was chosen due to its high volumetric energy density, good high-rate
performance, low self-discharge, state of charge indication, excellent safety characteristics,
and abuse resistance. Implementation of this chemistry would provide cells containing
non-noxious electrolytes with the performance and safety characteristics desired
for the applications mentioned. Phase II would involve the development of moderately
priced, spirally wound cells suitable for assembly into battery packs for ELT and
EPIRB use.

Potential Commercial Application:

Potential Commercial Applications:  These cells could be used in space applications,
buoys, weapons systems, and other applications requiring high rates over wide temperature
ranges.
