Evaluation of Zinc-Oxygen Cells with Advanced Components

Abstract:

Recent component technology innovations will be applied to the design of rechargeable
zinc-oxygen cells. The zinc-oxygen couple has long been recognized as having the
potential for very high energy density, however the system has been limited by problems
with oxygen electrode stability and zinc electrode shape change. The objective of
this project will be to demonstrate the feasibility of the battery using advanced
bifunctional electrode materials and separators. These component technologies will
be applied to the zinc-oxygen cell in a six-month program of cell fabrication and
testing. The development of a high energy-density, zinc-oxygen battery with extended
cycle life will provide a technology which meets many commercial and aerospace needs.
The need for portable power for space station equipment could be met by the battery.
Given the safe nature of the battery reactants and the inherent high energy-density
of the metal-gas system, it is one of the few couples which can meet the energy density
and safety concerns for aerospace uses. applications ranging from portable consumer
electronics to advanced electric vehicles could be served with a Zn-02 battery.
