A method and system for adapting the voltage supplied by a high performance electrochemical storage device provide for: supplying a voltage for a load using a high-performance electrochemical storage device; monitoring the temperature of the high-performance electrochemical storage device; an adapting the voltage supplied by the high-performance electrochemical storage device as a function of a change in the monitored temperature thereof in a way that counters a change in the value of the power density of the high-performance electrochemical storage device attributable to the temperature change.

Method for adapting the voltage supplied by a high-performance electrochemical storage device, and a system for operating a load

An aqueous electrolyte for a capacitor contains at least one transition metal complex. An aqueous electrolyte containing at least one transition metal complex can be used in a supercapacitor, in a pseudocapacitor, or in a hybrid supercapacitor. A hybrid supercapacitor contains an aqueous electrolyte, which contains at least one transition metal complex.

Aqueous electrolyte, use of the electrolyte and hybrid supercapacitor containing the electrolyte

A hybrid supercapacitor has two electrodes, one of which functions as a cathode, and the other as an anode. The hybrid supercapacitor further includes an electrolyte arranged between the cathode and the anode. The electrolyte contains a solvent selected from the group consisting of methanol, 1-propanol, 1-heptanol, ethyl acetoacetate, ethylene glycol, diethylene glycol, glycerol, benzyl alcohol, di-n-butyl phthalate and mixtures thereof.

Hybrid supercapacitor

A hybrid supercapacitor, including at least one negative electrode that includes a statically capacitive active material, an electrochemical redox active material, or a mixture thereof, at least one positive electrode that includes a statically capacitive active material, an electrochemical redox active material, or a mixture thereof, at least one separator that is situated between the at least one negative electrode and the at least one positive electrode, and an electrolyte composition, with the condition that at least one electrode includes a statically capacitive active material, and at least one electrode includes an electrochemical redox active material, the electrolyte composition being a liquid electrolyte composition and including at least one liquid, aprotic, organic solvent, at least one conducting salt, and at least one additive.

Hybrid supercapacitor, including an electrolyte composition, having improved conductivity

A hybrid supercapacitor, including at least one negative electrode having a statically capacitive active material, an electrochemical redox-active material, or a mixture of them; at least one positive electrode having a statically capacitive active material, an electrochemical redox-active material, or a mixture of them; at least one separator situated between the at least one negative electrode and the at least one positive electrode; and an electrolyte mixture; with the provision that at least one electrode includes a statically capacitive active material, and at least one electrode includes an electrochemical, redox-active material; the electrolyte mixture being a liquid electrolyte mixture and including at least one liquid, aprotic, organic solvent, at least one conducting salt, and at least one at least partially halogenated, aromatic compound.
