Abstract
An electrical double layer capacitor comprises an element and a case which houses the element. The element has an anode charge collector, anode, separator, cathode and cathode charge collector. The anode and cathode consist of a porous layer containing electrically conducting porous particles as a constituent material. The anode charge collector is disposed in electrical contact with the anode. The cathode charge collector is disposed in electrical contact with the cathode. The thickness of the element is 600 μm or less. The sum of the anode thickness and cathode thickness is set to 80% or less of the thickness of the element.
Claims8
An electrochemical device comprising:
- an element comprising first and second electrodes, and a separator separating said first and second electrodes,
- wherein said first and second electrodes comprise an electrically conducting active substance layer containing an electrically conducting substance as a constituent material, and an electrically conducting charge collector assembly disposed in electrical contact with said active substance layer, wherein:
- the thickness of said element is set to 600 μm or less, and
- the total thickness of said active substance layer contained in said first and second electrodes is set to 80% or less of the thickness of said element.
