Compositions and methods for multilayer electrode films

This invention describes a way to make the energy-storing parts of batteries or capacitors. It involves first creating two separate, flexible sheets, each made of an energy-storing material held together by a binder. These sheets are then pressed or rolled together to form a single, layered film, which can then be attached to a metal sheet that collects electricity.

Why it matters: The short time since filing means the core challenges of cost-effective, scalable manufacturing and achieving optimal interlayer adhesion for these specific capacitor electrodes likely persist.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedElectrode material handling, calendering, pressing equipment.
