Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
An electrode consisting essentially of a thin net type sheet having 50 to 3 mesh and a wire diameter of 0.15 to 2 mm and an elastic deformation factor of up to 1 mm under a load of 1 Kg/cm 2 which is covered with an electrochemically active material and said mesh electrode is supported by a foraminous planar electrode support having a higher overvoltage than that of said thin net type sheet with which said thin net is closely brought into contact.
Claim 2
Dependent Claim
83 words
An electrode consisting essentially of a thin net type sheet having 50 to 3 mesh and a wire diameter of 0.15 to 2 mm and an elastic deformation factor of up to 1 mm under a load of 1 Kg/cm 2 which is covered with an electrochemically active material and said mesh electrode is supported by a foraminous planar electrode support having a higher overvoltage than that of said thin net type sheet with which said thin net is closely brought into contact.
Claim 3
Dependent Claim
21 words
The electrode according to claim 1 wherein said thin net type sheet is a wire gauze or a gauze expanded metal.
Claim 4
Dependent Claim
28 words
The electrode according to claim 1 or 2 wherein said thin net is made of titanium, niobium, tantalum, iron, iron alloy, stainless steel, copper, nickel or nickel alloy.
