Abstract

A charge storage device (1) includes a sealed prismatic housing (2). Two opposed folded rectangular aluminium electrodes (3, 4) are disposed within housing (2) and connected to the electrodes. A porous, electronically insulating separator material, e.g. Solupor™, sheet separator (7) is disposed intermediate electrodes (3, 4) for maintaining those electrodes in a fixed spaced apart configuration. An electrolyte (not shown) is also disposed intermediate the electrodes. Collecting means in the form of a scavenging agent is grafted to separator (7) for sequestering one or more predetermined contaminants from the housing.

Description

FIELD OF THE INVENTION

[0001] The present invention relates to a charge storage device.

[0002] The invention has been developed primarily for supercapacitors and will be described hereinafter with reference to that application. However, the invention is not limited to that particular field of use and is also suitable for other charge storage devices such as capacitors, batteries, fuel cells and the like. DISCUSSION OF THE PRIOR ART

[0003] Supercapacitors in the form of electric double layer capacitors are known. These capacitors generally include a housing for two aluminium electrodes each of which have a coating of activated carbon or the like on at least one side. The electrodes are typically wound or otherwise interleaved together with an intermediate separator and wetted with an appropriate electrolyte. The charge is stored in the electric double layer which is formed between the carbon and the electrolyte. Due to the large surface area per volume of the activated carbon the cha...
