Electrochemical capacitor with electrode and electrolyte layers having the same polymer and solvent

摘要

An electrode material for an electrochemical capacitor and electrochemical capacitors utilizing the electrode material. The electrode material comprises electrically conductive carbon, a soluble salt, a non-aqueous liquid solvent, and a gel-former. Such a solid electrode material is especially well adapted for use in multi-layer capacitors in which such components can be made very thin, thereby providing a very low resistance for the device and permitting rapid discharge of the capacitor.
