Claim 7:
8. An accumulator comprising:
a cell;
an active mass; and
a plurality of electrode plates arranged adjacently within the cell to form an electrode plate stack, each electrode plate of the plurality of electrode plates comprising:
a frame having a frame thickness;
a grid arranged within the frame, the grid having a grid thickness and the grid being filled with a portion of the active mass;
a connecting lug protruding beyond the frame, the connecting lug having a lug thickness provided in an area forming a connecting lug block, the lug thickness being greater than the frame thickness and the frame thickness being greater than the grid thickness; and

a first portion of the electrode plate between the lug thickness and the frame thickness and a second portion of the electrode plate between the frame thickness and the grid thickness, the first portion having a first transitioning thickness from the lug thickness to the frame thickness and the second portion having a second transitioning thickness from the frame thickness to the grid thickness,
wherein the connecting lug block of the plurality of electrode plates further includes an electrical and mechanical bond coupling each of the connecting lugs of same-polarity electrode plates.
