| 摘要 |
The present invention is directed to super or ultracapacitors. The ultracapacitor includes at least one bipolar electrode plate (12), an electrolyte (14) and a separator (16). The bipolar electrode plate (12) includes a current collector and an electrode material associated with the current collector. The electrolyte (14), which is positioned between adjacently oriented bipolar plates, includes an organic aprotic solvent and a salt. A stabilizing additive is associated with the electrolyte for stabilizing electrochemical activity between the solvent and at least one of the current collector and the electrode material. In addition, the electrolyte may further include a wetting agent for increasing wettability of the electrode.
