NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 07.07-2699

PROJECT TITLE : NI-MH BATTERY FOR MANNED APPLICATIONS

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

The Nickel-Metal Hydride (Ni-MH) battery system offers the potential of high energy density, sealed operation and safety for manned space applications. Conventional cylindrical, coiled electrode cells are capable of 500+ cyclesbefore failure at an energy density of 60-65 Wh/kg. The object of this project is to develop the technology to build Ni-MH batteries capable of hundreds of cycles with an energy density greater than 100 Wh/kg at the cell leveland 80 Wh/kg at the battery level. These energy densities which would make this type of battery suitable for manned space applications ranging from hand held tools to EMU power packs.

Electro Energy, Inc. is developing a bipolar nickel-metal hydride (Ni-MH) battery. This novel packaging approach along with lightweight components, selected with some sacrifice in cycle-life, is proposed for development for manned space applications.

POTENTIAL COMMERCIAL APPLICATIONS
The main commercial application of this program would be rechargeable batteries whose applications range from portable electronic appliances to electric vehicles. Specialty small capacity commercial applications for Ni-MH batteries include computers, camcorders, and cellular phones.
