Title: Co-extruded conformal battery separator and electrode

Abstract

A co-extrusion print head has at least one separator inlet port, at least a first, second and third series of channels arranged to receive a separator material from the separator inlet port, at least one electrode inlet port, a fourth series of channels arranged to receive an electrode material from the electrode inlet port, a first merge portion connected to the first, second, third and fourth series of channels, the merge portion positioned to receive and merge the separator material into a separator flow and the electrode material into an electrode flow, a second merge portion connected to the first merge portion, the second merge portion positioned to receive and merge the separator flows and the electrode flows, and an outlet port connected to the second merge portion, the outlet port arranged to deposit the separator and electrode materials from the merge portion as a stack on a substrate.
