Abstract
The present invention provides polarized electrodes that ensure a satisfactory packing ratio of activated carbon particles and conductive particulates and favorable contact between these and an electrolyte, and demonstrate high capacitance. The present invention relates to the following electrode materials for polarized electrodes: (1) electrode materials for polarized electrodes containing a rubber-based emulsion, activated carbon particles, conductive particulates, and a surfactant; and (2) electrode materials for polarized electrodes containing a dispersion of polytetrafluoroethylene, activated carbon particles, conductive particulates, and a surfactant, wherein the solid content is 25% by weight or more.
Claims4
An electrode material for a polarized electrode, the electrode material comprising:
- a material prepared by:
- a first step of dispersing conductive particles and a surfactant in water;
- a subsequent second step of dispersing activated carbon particles, different from the conductive particles, in the dispersion obtained in the first step;
- and
- a third step of mixing a binder comprising rubber containing emulsion or a dispersion of polytetrafluoroethylene in the dispersion obtained in the second step.
