Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
66 words
An electric current-producing cell, comprising: (a) an anode having as its anode-active material one or more alkali metals; (b) a cathode having as its cathode-active material one or more polymer compounds having a plurality of carbon monosulfide units; and, (c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between anode and said cathode.
Claim 2
Dependent Claim
66 words
An electric current-producing cell, comprising: (a) an anode having as its anode-active material one or more alkali metals; (b) a cathode having as its cathode-active material one or more polymer compounds having a plurality of carbon monosulfide units; and, (c) an electrolyte which is chemically inert with respect to said anode and said cathode and which permits the migration of ions between anode and said cathode.
