Patent ID: 8304112

Claim:
An electrode plate assembly for an electricity storage/discharge device, comprising: an electrode plate having a generally planar surface and a plurality of sides at edges of said generally planar surface, said electrode plate having least one input/output current-collecting first terminal structure on a first of said sides of the electrode plate and at least one current-collecting second terminal structure on a second of said sides of the electrode plate, the first side being opposite the second side; an auxiliary electric conductor; and an insulator portioned between the electrode plate and the auxiliary electric conductor, wherein said at least one input/output current-collecting first terminal structure has a same polarity as said at least one current-collecting second terminal structure, and wherein said auxiliary electric conductor electrically connects at least one first terminal structure and said at least one second terminal structure at opposites of the electrode plate to provide an auxiliary current path for charges collected by the respective first and second terminal structures.
