Abstract: A method of manufacturing a composite structure for a battery that cycles lithium ions includes depositing a positive electrode precursor on a substrate to form a positive electrode layer, compacting the positive electrode layer, depositing a solid electrolyte precursor on the substrate over the positive electrode layer to form a solid electrolyte layer, compacting the solid electrolyte layer on the substrate over the positive electrode layer to form a composite structure, and heat treating the composite structure to sinter the solid electrolyte layer. The positive electrode precursor includes electroactive material particles, solid electrolyte particles, and electrically conductive particles. The solid electrolyte precursor includes solid electrolyte particles.
