Abstract
A method of 3D printing a battery includes extruding a first electrode ink formulation through a first deposition nozzle moving relative to a substrate, and depositing one or more continuous filaments comprising the first electrode ink formulation on the substrate to print a first electrode. A separator ink formulation is extruded through a second deposition nozzle moving relative to the substrate, and one or more continuous filaments comprising the separator ink formulation is deposited on the first electrode to print a separator precursor, which is then cured to form a separator. A second electrode ink formulation is extruded through a third deposition nozzle moving relative to the substrate, and one or more continuous filaments comprising the second electrode ink formulation is deposited to print a second electrode on the separator. The first and second electrodes and the separator are enclosed in a package, thereby forming a battery with thick electrodes.
