Abstract: Powderized solid-state electrolytes and electroactive materials as well as related methods of manufacturing and use are disclosed. In one embodiment, an ionically conductive powder comprises a plurality of ionically conductive particles. The ionically conductive particles may comprise an ionically conductive salt dissolved in a thermoplastic polymer, with optional components (e.g.,electroactive and/or inorganic solid particles) dispersed within. Related methods of producing these ionically conductive powders are also disclosed including, but are not limited to, low-temperature milling, spray drying, and aerosol polymerization. Embodiments related to using the resultant ionically conductive powders in a spray deposition process are also described.

Abstract: The invention is directed to a process for forming a particle film on a substrate. Preferably, a series of corona guns, staggered to optimize film thickness uniformity, are oriented on both sides of a slowly translating grounded substrate (copper or aluminum for the anode or cathode, respectively). The substrate is preferably slightly heated to induce binder flow, and passed through a set of hot rollers that further induce melting and improve film uniformity. The sheeting is collected on a roll or can be combined in-situ and rolled into a single-cell battery. The invention is also directed to products formed by the processes of the invention and, in particular, batteries.

Abstract: A system for forming a particle layer on a substrate may include at least one sprayer and at least two masks configured to selectively mask a substrate in a first region and second region of the substrate. The at least one sprayer may be configured to spray particles at the substrate, where the at least two masks maintain the first region and second region substantially free of the deposited material. A heater may be employed to heat the substrate as the particles are sprayed by the at least one sprayer onto the substrate.
