Claim 16:
17. A method for fabricating a battery unit comprising, by an assembly system:
at an anode assembly fabrication unit, generating a first anode assembly by:
coating first sides and second sides of a row of anode collectors, connected by a set of anode interconnects, with an anode material to form a set of anode electrodes; and
coating first sides of the set of anode electrodes, excluding a first anode electrode, in the set of anode electrodes with a separator material to form a first set of separators over first sides of the set of anode electrodes and the row of anode collectors;

at a cathode assembly fabrication unit, generating a first cathode assembly by:
coating first sides and second sides of a row of cathode collectors, connected by a set of cathode interconnects, with a cathode material to form a set of cathode electrodes; and
coating second sides of the set of cathode electrodes, excluding a last cathode electrode, in the set of cathode electrodes with the separator material to form a second set of separators over second sides of the set of cathode electrodes and the row of cathode collectors; and

at a folding station:
folding the first anode assembly across the set of anode interconnects to locate the row of anode collectors;
folding the first cathode assembly across the set of cathode interconnects to locate the row of cathode collectors;
interdigitating the first cathode assembly and the first anode assembly to form a first folded battery cell stack;
wetting the first set of separators and the second set of separators, in the first folded battery cell stack, with ions; and
loading the first folded battery cell stack into a battery housing to form a first battery unit.
