Development of Sintered Fiber Nickel Electrodes for Aerospace Batteries

The nickel electrode is the specific energy limiting component in nickel battery systems. A concerted effort is currently underway to improve NiH2 performance while decreasing system cost. Increased performance with electrode specific energy (mAh/g) is the major goal of this effort. However, cost reduction is also an important part of the overall program, achieved by reducing the electrode weight. A lightweight, high energy density, nickel electrode is being, developed based on a highly porous, sintered fiber, nickel substrate. This developing technology has many applications, but is highly, applicable to the military and aerospace industries.

NASA NTRS1989

Multi-mission Ni-H2 battery cells for the 1990's

A sufficient production, test and operational database is now available to permit design technology optimization for the next decade. The evolved battery cell design features standardized technology intended to support multiple type missions (e.g., both GEO and LEO). Design analysis and validation test cells demonstrate that improved performance plus attractive specific-energy characteristics will be achieved.
