Patent ID: 7541112

Claim:
An electrochemical cell (EC) bundle, comprising: a plurality of cells, each cell comprising: a) a pair of sheet-like electrodes, each sheet-like electrode having a first length in a first direction and a second length in a second direction perpendicular to the first direction; b) an electrolyte between said sheet-like electrodes; c) a sheet-like current collecting element projecting from at least one of said sheet-like electrodes in the first direction and electrically connected to said at least one of said sheet-like electrodes, said current collecting element having a pair of generally opposite main faces projecting from said at least one of said sheet-like electrodes in the first direction and extending the entire second length of said at least one of said sheet-like electrodes; said plurality of cells being arranged into a stack such that said sheet-like current collecting elements of the respective cells are side-by-side with the main faces of the respective sheet-like current collecting elements facing one another; a current collecting terminal having a pair of arms in a spaced apart relationship extending along the entire second length of each of said at least one of said sheet-like electrodes; each of said arms overlapping and pressing the main faces of said sheet-like current collecting elements of the stack of cells together thereby electrically connecting the sheet-like current collecting element of each said sheet-like electrode together to said current collecting terminal.
