A multi-layer electrode includes a current collector having opposing first and second major surfaces, a fused carbon layer formed over one or both of the major surfaces, a conductive adhesion layer formed over each fused carbon layer, and an activated carbon layer formed over each conductive adhesive layer. The multi-layer electrode can be incorporated into a high energy density, high power density device such as an electric double layer capacitor.

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.
摘要:
A non-activated, majority non-graphitic amorphous carbon material may be produced by supplying a carbonized precursor material, heating the carbonized precursor material in a first heating step at a temperature and for a duration sufficient to produce a heat-treated carbon material that has a specific surface area less than about 500 m2/g and is less than about 20% graphitic by mass, purifying the heat-treated carbon material, and heating the purified heat-treated carbon material in a second heating step at a temperature and for a duration to produce a non-activated, majority non-graphitic amorphous carbon material that has a specific surface area less than about 500 m2/g and is less than about 20% graphitic by mass.
