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.
La présente invention concerne des super-condensateur ou ultra-condensateurs. Cet ultra-condensateur comprend au moins une plaque d'électrode bipolaire (12), un électrolyte (14) et un séparateur (16). La plaque d'électrode bipolaire (12) comprend un collecteur de courant et un matériau d'électrode associé audit collecteur. L'électrolyte (14), situé entre plaques bipolaires orientées de manière adjacente, comprend un solvant aprotique organique et un sel. Un additif stabilisant est associé à l'électrolyte afin de stabiliser l'activité électrochimique entre le solvant et le collecteur de courant et/ou le matériau d'électrode. En outre, l'électrolyte peut comprendre également un agent mouillant servant à accroître la mouillabilité de l'électrode.
