Abstract: A method for making a battery is disclosed which comprises providing a plurality of Electrochemical Cell (EC) bundles; providing a current collecting terminal having first and second ends; electrically connecting the projections of the sheet like electrodes extending from one end 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 and second EC bundles are mechanically and electrically connected together and form a string of at least two EC bundles; and folding the string of at least two EC bundles by bending the current collecting terminal connecting the at least two EC bundles together such that the first and second EC bundles are positioned in a side by side relationship.
