Embodiments of the invention generally relate to solid state battery structures, such as Li-ion batteries, methods of fabrication and tools for fabricating the batteries. One or more electrodes and the separator may each be cast using a green tape approach wherein a mixture of active material, conductive additive, polymer binder and/or solid electrolyte are molded or extruded in a roll to roll or segmented sheet/disk process to make green tape, green disks or green sheets. A method of fabricating a solid state battery may include: preparing and/or providing a green sheet of positive electrode material; preparing and/or providing a green sheet of separator material; laminating together the green sheet of positive electrode material and the green sheet of separator material to form a laminated green stack; and sintering the laminated green stack to form a sintered stack comprising a positive electrode and a separator.
