DEVICE TO PREVENT OVERPRESSURE IN A SUPERCAPACITOR |
摘要 |
The present invention relates to a device to prevent overpressure in a supercapacitor. In a supercapacitor comprising a closed chamber fitted with means for exchanging a gas with the external surroundings and in which there are positioned two electrodes with a high specific surface area, separated by a separator, the separator and the electrodes being impregnated with an electrolyte, the means for exchanging a gas comprise a metallic membrane that is permeable to hydrogen and its isotopes and impermeable to gaseous species which have an effective cross section of 0.3 nm or higher, at a temperature of between -50° C. and 100° C. |
