Abstract
Abstract An electrode for use in an organic cell is provided by forming a thin film of a metal such as aluminum on the sheet of an organic electroconductive material such as polyacetylene by, for example, a vacuum evaporation method, and then forming an atom-interdiffused layer at the interface between the sheet and the thin film by a recoil ion implantation method, thereby enhancing the current collecting efficiency of the electrode.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
85 words
A process for forming an electrode of an organic electroconductive material for use in an organic cell, in which a thin film of a metal is formed on the surface of at least a part of at least one side of the organic electroconductive material in a sheet form at such a temperature that no thermal deterioration occurs in said organic material, and then an atom-interdiffused layer is formed at the interface between said thin film and said electrode by a recoil ion implantation method.
Claim 2
Dependent Claim
85 words
A process for forming an electrode of an organic electroconductive material for use in an organic cell, in which a thin film of a metal is formed on the surface of at least a part of at least one side of the organic electroconductive material in a sheet form at such a temperature that no thermal deterioration occurs in said organic material, and then an atom-interdiffused layer is formed at the interface between said thin film and said electrode by a recoil ion implantation method.
Claim 3
Dependent Claim
16 words
The process according to claim 1, wherein the organic electroconductive material is polyacetylene, polyparaphenylene or polypyrrole.
Claim 4
Dependent Claim
18 words
The process according to claim 1, wherein the metal forming the thin film is aluminum, nickel or tin.
Claim 5
Dependent Claim
26 words
The process according to claim 1, wherein the thin film is so configured that it will not cover the whole surface of said organic material electrode.
Claim 6
Dependent Claim
28 words
