NOVELTY - The battery has an anode stack (222) including anode structures (102a, 102b) formed over a surface of an anodic current collector (111). A cathode stack (202) comprises a cathodic current collector (113). Cathode structures (103a, 103b) i.e. porous structures, are formed over a surface of the cathodic current collector. An integrated separator is formed between the anode stack and the cathode stack. A ceramic layer contacts a surface of the anode structure and another ceramic layer contacts a surface of the cathode structure.    USE - Lithium-ion battery. Uses include but are not limited to a portable electronic application, medical application, transportation application, grid-connected large energy storage application, renewable energy storage application and an uninterrupted power supply (UPS).    ADVANTAGE - The integrated separator is formed between the anode stack and the cathode stack so as to prevent direct electrical contact between components in the anode structure and the cathode structure. The integrated separator can be produced at low cost so as to achieve improved performance. The separator has high porosity for good ionic conductivity, complex pore structure to suppress lithium short, build-in safety shutdown feature, excellent thermal and mechanical stability.    DETAILED DESCRIPTION - The ceramic layers comprise a binder selected from polyvinylidene fluoride (PVDF), carboxymethyl cellulose (CMC) and styrenebutadiene (SBR). The cathode structure comprises cathodically active material selected from a group consisting of lithium cobalt dioxide, lithium manganese dioxide and titanium disulfide. The ceramic layers include ceramic particles selected from a group consisting of hafnia, titania, silica, alumina and zirconia. INDEPENDENT CLAIMS are also included for the following:    (1) a method for forming an electrode structure    (2) a substrate processing system for processing an integrated separator over a flexible conductive substrate.
