NOVELTY - The packaging (101) has a cylindrical, oblong or prismatic shape housing comprising an active coating i.e. activated carbon coating. The coating comprises a binder and/or adhesion agent. The active coating covers a surface of the housing that is in contact with active surfaces of an electrochemically active material. A pre-coating includes a conduction enhancing agent that is chosen from carbon blacks. The active coating covers a portion of a side of a substrate e.g. aluminum sheeting.    USE - Packaging i.e. cylindrical or oblong or prismatic packaging, for an electrochemically active material i.e. activated carbon, of an electrochemically active device i.e. Capacitor such as ultracapacitor. Can also be used for active material such as graphite, pyrolized carbon, hard carbon, lithium metal, zinc metal, fuel cell, platinum black, platinum metal, biocatalytic films and membranes, and aluminum oxide in electrochemical double layer capacitors, primary and secondary batteries, fuel cells and a supercapacitor.    ADVANTAGE - The packaging ensures that increased effective amounts of electrochemically active component can result in increased activity such as increased energy storage capacity, for the electrochemically active device, thus improving volumetric efficiency of the device. The packaging facilitates heat transfer from an interior of the packaging to the exterior of the device. The packaging protects the housing from reactions so as to prevent the housing from being degraded and/or avoid affecting the performance or long term stability of the device.    DETAILED DESCRIPTION - The binding and/or adhesion agents are polytetrafluoroethylene, polyvinylidene fluoride, polyvinylpyrrolidone, polyvinyl acetate, polyethylene oxide, polypropylene, polyethylene, polyurethane and polyacrylates. An INDEPENDENT CLAIM is also included for a method for making packaging for an electrochemically active material.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a packaging for electrochemically active materials.    Packaging (101)    Walls (102)    Open bottom (103)    Partial top (104)
