摘要： A method is provided for developing a hybrid supercapacitor. The method includes the use of a lithium salt of the electrolyte to carry out the intercalation/insertion of the lithium at the negative electrode but by greatly increasing the concentration of lithium ions of the electrolyte order to subsequently accept a depletion. As the depletion in ions has an impact on the conductivity, the amount and the concentration of the electrolyte are chosen in order to make it possible to accept this depletion white retaining a conductivity of the electrolyte compatible with a powerful system for storage of energy. A portion of the Li+ ions present in the electrolyte is used to form the passivation layer and the compound for intercalation/insertion Li˜0.5C6 at the negative electrode.
