NASA 1996 SBIR Phase I


PROPOSAL NUMBER : 96-1 07.07-9029

PROJECT TITLE : : NiH2 Spacecraft Batteries with Effective Performance >100 W-hr/kg

TECHNICAL ABSTRACT (LIMIT 200 WORDS)

In this research Boundless Corp. will prove the feasibility of combining NiH2 batteries with spacecraft honeycomb structures. The resulting device, called PowerCore, will significantly improve spacecraft energy storage. Our research will be an extrapolation our ongoing work for DOE on a similar device for terrestrical applications using NiMH electrochemistry. This new NASA Phase I research will fabricate and test a critical electrode stack with a Pt negative electrode. Our vision is to improve overall space system performance by using PowerCore to eliminate battery volume, achieve an effective energy storage performance better than 100 w-hr/kg, and retain a cycle life of tens of thousands of cycles like current NiH2 batteries. Spacecraft structure and batteries rank first and second, respectively, in the mass budgets of most unfuelled, unmanned spacecraft. Honeycomb sandwich panels are widely used in spacecraft structure. We will prove the feasibility of replacing the inert honeycomb core with electrochemically active NiH2 battery materials. The new device, called PowerCore, will maintain the structural characteristics of honeycomb while also serving as a battery with extremely long cycle life as compared with emerging Li and NiMH technology.
POTENTIAL COMMERCIAL APPLICATIONS
Commercial applications for PowerCore include spacecraft and extend to electric vehicles, portable electronics, and cordless power tools. All of these devices benefit from lighter-weight and longer operating time achievable by integrating structure and batteries.
