Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
37 words
A lithium-halogen battery in which at least one of the electrical leads of at least one of the electrodes is provided, on at least a portion of its length, with a protective layer of a lithium halide.
Claim 2
Dependent Claim
37 words
A lithium-halogen battery in which at least one of the electrical leads of at least one of the electrodes is provided, on at least a portion of its length, with a protective layer of a lithium halide.
Claim 3
Dependent Claim
13 words
The battery of claim 1 in which the lead is an anode lead.
Claim 4
Dependent Claim
19 words
The battery of claim 2 in which the coating is lithium initially and the halide is formed in situ.
Claim 5
Dependent Claim
11 words
The battery of claim 3 wherein the halide is lithium iodide.
Claim 6
Dependent Claim
13 words
The battery of claim 1 in which the lead is a cathode lead.
Claim 7
Dependent Claim
19 words
The battery of claim 4 in which the coating comprises iodine initially and lithium iodide is formed in situ.
Claim 8
Dependent Claim
16 words
The battery of claim 3 including a lithium anode comprising a lithium-coated collector and anode lead.
Claim 9
Dependent Claim
50 words
As a battery sub-assembly, an anode collector, an anode lead attached thereto and a feedthrough body attached to the anode lead, the subassembly including a lithium coating extending over the collector surface, the anode lead surface between the collector and the feedthrough body, the coating overlapping onto the feedthrough body.
Claim 10
Dependent Claim
50 words
As a battery sub-assembly, an anode collector, an anode lead attached thereto and a feedthrough body attached to the anode lead, the subassembly including a lithium coating extending over the collector surface, the anode lead surface between the collector and the feedthrough body, the coating overlapping onto the feedthrough body.
Claim 11
Dependent Claim
21 words
The sub-assembly of claim 8 including a header to which the feedthrough body is attached and through which the lead extends.
