Inventor： Denis Phares , Justin S. Ferranto
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.
