Dual-layer method of fabricating ultracapacitor current collectors

摘要

A method of making a multi-layer current collector comprises forming a first layer from a first formulation over each major surface of a current collector substrate, and forming a second layer from a second formulation over each of the first layers, wherein one of the first formulation and second formulation is a graphite formulation and the other of the first formulation and second formulation is a carbon black formulation.

1. A method for making a multi-layer current collector, the method comprising:
forming a first layer from a first formulation in direct contact with each major surface of a current collector substrate; and forming a second layer from a second formulation in direct contact with each first layer; wherein the first formulation is one of a graphite formulation and a carbon black formulation, and the second formulation is the other of a graphite formulation and a carbon black formulation, and the graphite formulation comprises at least one graphite material having an average particle diameter ranging from 0.1 μm to 100 μm.
