Abstract: 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.

Abstract: One variation of a method for fabricating an electrolyte includes: depositing an electrolyte material over a substrate, the electrolyte material including a monomer miscible in a first volume of solvent, a polymer semi-miscible in the monomer and miscible in the first volume of solvent, and a photoinitiator; exposing the electrolyte material to electromagnetic radiation to disassociate the photoinitiator into a reactive subspecie that crosslinks the monomer to form an electrolyte structure with the polymer phase-separated from the electrolyte structure; dissolving the polymer out of the electrolyte structure with a second volume of solvent to render a network of open-cell pores in the electrolyte structure; and exposing the electrolyte structure to a third volume of solvent and ions to fill the network of open-cell pores with solvated ions.

Abstract: 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.
