Abstract
A method of making a polarizable electrode for an electric double layer capacitor, includes adding a binder assistant to a binder so that the binder is swollen and mixing a carbonaceous powder, a conductive assistant and thereafter the swollen binder, thereby obtaining a material mixture, kneading the material mixture into a primary forming material, forming the primary forming material into a secondary forming material, and rolling the secondary forming material into a sheet shape.

A method of making a polarizable electrode for an electric double layer capacitor, comprising:
- adding a binder assistant to a binder so that the binder is swollen and mixing a carbonaceous powder, a conductive assistant and thereafter the swollen binder, thereby obtaining a material mixture;
- kneading the material mixture into a primary forming material;
- forming the primary forming material into a secondary forming material;
- and
- rolling the secondary forming material into a sheet shape.
A method of making a polarizable electrode for an electric double layer capacitor, comprising:
- a mixing step including a primary mixing in which a carbonaceous powder and a conductive assistant are mixed into a primary mixture and a secondary mixing in which a binder and a binder assistant are added to the primary mixture to be mixed into a material mixture;
- a kneading step in which the material mixture is kneaded into a primary forming material;
- a forming step in which the primary forming material is formed into a secondary forming material;
- and
- a rolling step in which the secondary forming material is rolled into a sheet shape.
