Representative claim 1 reads as follows:
1. A primary electrochemical battery cell comprising a container, a
first positive electrode comprising a manganese oxide and a carbon, a first
negative electrode comprising zinc, a separator disposed between adjacent
positive and negative electrodes, and an electrolyte comprising an aqueous
alkaline solution; wherein
the cell comprises a second of at least one of the positive and negative
electrodes;
all first and second electrodes are disposed coaxially with respect to
each other, with alternating polarities, such that each of the first and second
electrodes has at least one surface that interfaces with another of the coaxial
electrodes through the separator; and
at least the first positive electrode contains greater than 60 percent but
not greater than 80 percent solid materials by volume.
The prior art set forth below is relied upon by the Examiner as
