Abstract
Abstract The present invention is directed to an electric current-producing cell which contains: (a) an anode having as its anode-active material one or more metals selected from a group consisting of Periodic Table Group Ia metals, Group Ib metals, Group IIa metals and Group IIb metals; a cathode, comprising: (i) metalized containment means having a plurality of apertures therein, said apertures having an average cross-sectional dimension of about 1 to about 100 microns; and (ii) cathode-active molybdenum sulfide contained within said metalized containment means; and (c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between said anode and said cathode.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
107 words
An electric current-producing cell, comprising: (a) an anode having as its anode-active material one or more metals selected from the group consisting of the Periodic Table Group Ia metals, Group Ib metals, Group IIa metals and Group IIb metals; (b) a cathode, comprising: (i) metalized containment means having a plurality of apertures therein, said apertures having an average cross-sectional dimension of about 1 to about 100 microns; and (ii) cathode-active molybdenum sulfide contained within said metalized containment means; and, (c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between said anode and said cathode.
Claim 2
