Embodiment Construction

[0019] In all the specific embodiments of the hybrid supercapacitor 1 described below, they have the configuration shown in the drawings. It has LiMn contained in the activated carbon matrix 2 o 4 Cathode 2. The cathode 2 is applied to the first collector (Kollektor) 3 . In addition, the hybrid supercapacitor 1 has Li in the activated carbon matrix 4 Ti 5 o 12 constitute the anode 4. The anode 4 is applied to the second collector 5 . An electrolyte 6 is provided between the cathode 2 and the anode 4. A porous membrane 7 separates the two electrodes 2, 4 from each other. Li is schematically shown in four enlarged views in the accompanying drawings + Ions are intercalated into cathode 2 and anode 4.

Abstract

A hybrid supercapacitor includes an electrolyte (6). 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.

Description

technical field [0001] The present invention relates to hybrid supercapacitors characterized by their electrolyte composition. Background technique [0002] Hybrid supercapacitors (HSCs), such as Li-ion capacitors, are a new generation of supercapacitors that can deliver higher power than Li-ion battery packs. Although lithium-ion batteries have a large energy density of more than 100 Wh / kg, this energy can only be released slowly. Hybrid supercapacitors have a higher energy density compared to supercapacitors (EDLC / SC) which have a low energy density although they can provide a power delivery of more than 100 kW / kg. Hybrid supercapacitors can be charged, for example, by means of short high-energy pulses, as occurs during recuperation of braking energy in motor vehicles. The electrical energy recovered in this way can then be used to accelerate the motor vehicle. This saves fuel and reduces CO2 emissions. Hybrid supercapacitors can also be considered as energy sources fo...
