| 摘要 |
The invention provides an electrochemical capacitor which comprises positive and negative electrodes made of conducting p-dopable polyaniline, directly polymerized on high porosity carbon substrates and a polymer electrolyte layer, comprising a polymer matrix and a ionic conductive compound. The capacitor further comprises two outer conductive layers, a spacer for creating a gap between the electrodes, and sealing means. A method of making the capacitors is disclosed, which comprises effecting chemical or electrochemical polymerization of the aniline over the substrate. The electrochemical capacitors of the invention are simple to manufacture and require the use of cheap materials only. They have a higher specific capacitance and a higher energy density than the prior art electrochemical capacitors. |
