Claim 0:
1. An electrode system comprising:
a plurality of first electrode plates and a plurality of second electrode plates arranged alternatingly to form an electrode stack,
each first electrode plate having a first electrode plate first busbar opening and a first electrode plate second busbar opening extending through the first electrode plate, the first electrode plate second busbar opening being larger than the first electrode plate first busbar opening,
each second electrode plate having a second electrode plate first busbar opening extending through the second electrode plate, the second electrode plate first busbar opening being dimensioned larger than each of the first electrode plate first busbar openings and aligned with the first electrode plate first busbar openings, and a second electrode plate second busbar opening extending through the second electrode plate, the second electrode plate second busbar opening being dimensioned smaller than each of the first electrode plate second busbar openings and aligned with the first electrode plate second busbar openings,
a first busbar extending through the first electrode plate first busbar openings and the second electrode plate first busbar openings, the first busbar being configured to be in mechanical contact with an inner first busbar surface of the first electrode plate first busbar openings only, and
a second busbar extending through the first electrode plate second busbar openings and the second electrode plate second busbar openings, the second busbar being configured to be in mechanical contact with an inner second busbar surface of the second electrode plate second busbar openings only,
wherein the first electrode plates have an electrically conductive first frame which delimits a respective first inner volume and the second electrode plates have an electrically conductive second frame which delimits a respective second inner volume, the frames being coated with a heat conductive polymer, wherein the first electrode plates and second electrode plates have an exposed region where a metal core has been exposed,
the exposed region of the first electrode plates being provided with the first electrode plate first busbar opening and the first electrode plate second busbar opening,
the exposed region of the second electrode plates being provided with the second electrode plate first busbar opening and the second electrode plate second busbar opening, and
a plurality of electrically conducting spacers, each having a through-opening receiving a first or a second busbar, wherein for each of the first electrode plates and the second electrode plates respective two spacers are arranged in electrical connection with the exposed region, one spacer being arranged on one side of the corresponding first electrode plate first busbar opening or second electrode plate second busbar opening and another spacer being arranged on the opposite side thereof, wherein both the front and the rear surfaces of the exposed regions are in mechanical and electrical contact with a respective spacer.
