Patent ID: 8142523

Claim:
A method for making a battery, said method comprising: a) providing a plurality of Electrochemical Cell (EC) bundles, each EC bundle comprising a plurality of Electrochemical Cells (ECs), each Electrochemical Cell comprising: i) a sheet-like positive electrode having a projection extending from a first end of said Electrochemical Cell; ii) a sheet-like negative electrode having a projection extending from a second end of said Electrochemical Cell; iii) an electrolyte between said electrodes; b) providing a current collecting terminal having a first end and a second end; electrically connecting the projections of the sheet like electrodes extending from one end of a first EC bundle together via the first end of the current collecting terminal; electrically connecting the projections of the sheet like electrodes extending from one end of a second EC bundle together via the second end of the current collecting terminal such that the first EC bundle and the second EC bundle are mechanically and electrically connected together and form a string; wherein a plurality of EC bundles are assembled and electrically connected together via current collecting terminals to form a continuous string of EC bundles and thereafter folding the string of successive EC bundles into an accordion or zigzag configuration by bending the current collecting terminals connecting the EC bundles together such that the EC bundles are positioned in a side by side relationship.
