In one aspect, a method for manufacturing a battery includes forming a battery cell relative to a substrate using a layer-deposition sub-process, with the layer-deposition sub-process including: depositing a layer of first electrode material relative to the substrate; depositing a first layer of electrolyte material on top of the layer of first electrode material; depositing a layer of second electrode material on top of the first layer of electrolyte material; and depositing a second layer of electrolyte material on top of the layer of second electrode material. Additionally, the method includes cycling through the layer-deposition sub-process one or more additional times to form one or more additional battery cells relative to the substrate, with each additional battery cell being formed on top of a previously formed battery cell such that a battery cell stack is created relative to the substrate.

The invention relates to a battery, namely a lithium-ion battery, with an electrode layer and a current conductor, wherein the electrode layer has a plurality of auxiliary channels in an active material. The battery is improved in that the auxiliary channels are formed both at a cathode and at an anode.

Custom-form batteries can supply complex, practical systems with an optimal energy density that wouldn't otherwise be possible using traditional battery form-factors. For example, iron disulfide (FeS.sub.2) is a prominent conversion cathode of commercial interest. 3D direct-ink write (DIW) printing of FeS.sub.2 inks can be used to produce ridged cathodes from the filamentary extrusion of highly concentrated FeS.sub.2 inks (60-70% solids). These ridged cathodes exhibit optimal power, uniformity, and stability when cycled at higher rates (in excess of C/10). Meanwhile, functional cells with custom-form wave-shaped electrodes (e.g., printed FeS.sub.2 cathodes and pressed lithium anodes) exhibit improved performance over similar cells in planar configurations. In general, the DIW of concentrated inks is a viable path toward the making of custom-form conversion lithium batteries. More broadly, ridging is found to optimize rate capability.

To lower electrical resistance by increasing the interfacial surface area and the adhesion between a current collector and an active material or an electrolyte, or between the active material and the electrolyte in an all-solid-state battery. In addition, to improve battery performance by eliminating or minimizing residual carbon originating from a binder. A slurry, composed of an electrode active material and a solvent, and a slurry, composed of electrolyte particles and a solvent, can be impacted against a target and thereby attached thereto to form a high-density layer and improve adhesion. Moreover, residual carbon is eliminated or minimized by eliminating or minimizing the content of binders, thereby improving battery performance.

A new solvent-based method is presented for making low-cost composite graphite electrodes containing a thermoplastic binder. The electrodes, termed thermoplastic electrodes (TPEs), are easy to fabricate and pattern, give excellent electrochemical performance, and have high conductivity (1500 S m.sup.1). The thermoplastic binder enables the electrodes to be hot embossed, molded, templated, and/or cut with a CO.sub.2 laser into a variety of intricate patterns. These electrodes show a marked improvement in peak current, peak separation, and resistance to charge transfer over traditional carbon electrodes. The impact of electrode composition, surface treatment (sanding, polishing, plasma treatment), and graphite source were found to impact fabrication, patterning, conductivity, and electrochemical performance. Under optimized conditions, electrodes generated responses similar to more expensive and difficult to fabricate graphene and highly oriented pyrolytic graphite electrodes. These TPE electrodes provide an approach for fabricating high-performance carbon electrodes with applications ranging from sensing to batteries.
