    摘要： A method includes, by a folding station: receiving an anode assembly including anode collectors connected by anode interconnects and coated with a separator; receiving a cathode assembly including cathode collectors connected by cathode interconnects; locating a first anode collector over a folding stage; locating a first cathode collector over the first anode collector to form a first battery cell between the first anode collector and the first cathode collector; folding a first anode interconnect to locate a second anode collector over the first cathode collector to form a second battery cell between the first cathode collector and the second anode collector; folding a first cathode interconnect to locate a second cathode collector over the second anode collector to form a third battery cell between the second anode collector and the second cathode collector; wetting the separator with solvated ions; and loading the anode and cathode assemblies into a battery housing.

    摘要： One variation of a battery unit includes: a series of anode collectors; a set of anode electrodes including anode material arranged on both side of the anode collectors; a set of anode interconnects interposed between and electrically coupling adjacent anode collectors and folded to locate the anode collectors in a boustrophedonic anode stack; a series of cathode collectors; a set of cathode electrodes including cathode material arranged on both side of the cathode collectors; a set of cathode interconnects interposed between and electrically coupling adjacent cathode collectors and folded to locate the cathode collectors in a boustrophedonic cathode stack with cathode collectors interdigitated between anode collectors in the boustrophedonic anode stack; and a set of separators arranged between the anode and cathode electrodes and transporting solvated ions between the anode and cathode electrodes.

    摘要： One variation of a method for forming a battery includes: fabricating an anode collector in a region of a conductive film over a substrate; fabricating a cathode collector, interdigitated with the anode collector, in the region of the conductive film; forming an anode coupon of an anode material over the region of the conductive film; ablating the anode coupon to selectively remove segments of the anode material from the anode coupon and to form a set of anode fins over the anode collector; forming an electrolyte film across the set of anode fins; and depositing a cathode material over the cathode collector and between adjacent anode fins in the set of anode fins to form an interdigitated cathode.

    摘要： One variation of the method includes: receiving a section of a substrate tape including a substrate within a coating zone; dispensing a volume of separator material droplets onto the first substrate, each droplet in the volume of separator material droplets including a first solvent, a first polymer, and a second polymer; heating the substrate and the proportion of the separator material to a first temperature; dissolving the second polymer out of the volume of separator material droplets to render an open-celled network of pores by washing the volume of separator material droplets and the substrate with a second solvent; and irradiating the volume of separator material droplets to crosslink the first polymer and form a discrete separator layer with the open-celled network of pores sized to transport ions through the discrete separator layer.
