An energy storage device in the form of a cylindrical double layer capacitor (1) includes a plurality of integrally formed first electrode members (2) which each extend between a first end (3) and a second end (4). A plurality of integrally formed second electrode members (5) each extend between a third end (6) and a fourth end (7). As shown, members (5) are interleaved with members (2) such that ends (7) are located intermediate ends (3, 4) of the adjacent members (2). An insulator in the form of carbon layer (8) are disposed between adjacent members (2, 5) to prevent electrical contact therebetween. First contact means in the form of flanges (11) extend from respective ends (3) of each member (2) and electrically connect all the first members. Flanges (11) provide a site for the metallisation of particles thereupon. Those particles form a porous connection layer (12) for an electrical terminal (13) for members (2). Flanges (11) also form a barrier against the ingress of the particles beyond ends (3).
