Energy storage device
First Claim
1. An electrode pair for a supercapacitor, the electrode pair including:
- a first sheet electrode having a conductive energy storage element with an outer surface and a separator sheet being captively retained in abutment with the surface; and
a second sheet electrode having a conductive energy storage element with an outer surface that is abutted with the separator sheet whereby the elements are maintained in a spaced apart configuration.

Abstract
A surface mount energy storage device in the form of a supercapacitor (1) includes a generally rectangular folded prismatic housing (2) and two energy storage elements (not shown) that are sealingly contained within the housing (2) and which are connected in series. A mount, in the form of an integrally formed tinned metal frame (3), extends about and captively retains housing (2) in the folded configuration shown. Two terminals, in the form of elongate contacts (4, 5) extend from the energy storage elements and terminate outside housing (2) for allowing external electrical connection to the elements.
