STATEMENT OF WORK
9 Ampere-Hour Prismatic Mercuric Oxide/Zinc Cell
1. INTRODUCTION
This document describes the U. S. Government's need for the
development and engineering of a capability to fabricate moderate
numbers of highly reliable, sealed, high energy density mercuric
oxide/zinc cells. One hundred ten (110) sample cells will be
delivered for evaluation 9 months after contract start. Later
phases of this program may involve the construction of 550 cells
for qualification in FY-79 and 1 -- 2,000 cells for operational
use in FY-80. This contract action involves the first phase only
(Task 1).
2. PROJECT GOALS
The contractor will review existing electrochemical and
mechanical performance parameters and process techniques for
mercuric oxide/zinc cell construction. The contractor will then
duplicate the design of this cell which could reasonably be expected
to meet the target specifications. Sample cells will then be
tested against those specifications. Additional design work will
be conducted to overcome any shortcomings in performance. A
statistically significant number of cells will be constructed
and tested to confirm design performance against the electrical,
mechanical, and enviornmental requirements. One hundred ten (110)
engineering samples will be delivered to the government for test
and evaluation. All engineering test data, design drawings, and
process specifications will be included in a final report.
