CO-EXTRUSION PRINT HEAD FOR MULTI-LAYER BATTERY STRUCTURES

摘要

A co-extrusion print head capable of extruding at least two layers vertically in a single pass having a first inlet port connected to a first manifold, a first series of channels connected to the first inlet port arranged to receive a first fluid from the first inlet port, a second inlet port connected to one of either a second manifold or the first manifold, a second series of channels connected to the second inlet port arranged to receive a second fluid from the second inlet port, a merge portion of the print head connected to the first and second series of channels, the merge portion arranged to receive the first and second fluids, and an outlet port connected to the merge portion, the outlet port arranged to deposit the first and second fluids from the merge portion as a vertical stack on a substrate.

主权项

1. A method of manufacturing a vertically stacked electrical structure, comprising:
forming an anode slurry, a cathode slurry, and a separator slurry; and depositing the anode slurry, cathode slurry and separator slurry onto a substrate in one pass using a multi-layer co-extrusion print head, forming an intermediate battery structure.
