摘要:
A method is provided for forming a fullerene layer on a substrate by chemically treating a surface of the substrate to provide a bond-forming species at the surface effective to covalently bond with fullerenes in solution and contacting the treated substrate surface with a solution of fullerenes to form a fullerene layer covalently bonded to the treated substrate surface. Alternately or in addition, a fullerene layer is formed on a substrate by chemically modifying fullerenes to provide a bond-forming species thereon, chemically treating a surface of the substrate to provide a bond-forming species effective to covalently bond with the bond-forming species of the fullerenes in solution, and contacting a solution of treated fullerenes with the treated substrate surface to form a fullerene layer covalently bonded to the treated substrate surface.A three dimensional multilayer fullerene structure can be formed on the substrate surface by chemically modifying an initial fullerene layer formed thereon in the manner described above to provide chemical bridging species (e.g. piperazine) covalently bonded thereto and effective to covalently bond with fullerenes in solution. The modified fullerene film then is contacted with a solution of modified or unmodified fullerenes to form a second fullerene layer covalently bonded to the initial fullerene layer by the chemical bridging species. The method can be repeated to build up additional fullerene layers on the substrate surface.

An electrochemical cell is presented. The electrochemical cell includes an anode, a separator, and a cathode. The separator is coupled to the anode and to the cathode. The cathode comprises a first layer, a second layer, and a single current collector. The first layer includes a first surface and a second surface. A second layer, less than 2 mils thick, is introduced over the first surface of the first layer without a current collector being disposed between the first and the second layers. The current collector is coupled to the second surface of the first layer.

The present teachings include an electrochemical cell including an anode, a cathode, an electrolyte, a separator disposed between the cathode and anode, and a housing containing the anode, cathode, electrolyte, and separator. The separator can include a first sheet consisting essentially of a single layer material and a second sheet distinct from the first sheet. The second sheet can include an inner microporous layer laminated between two more outer layers. In some cells, the inner layer can have a transition temperature between a porous configuration and a substantially non-porous configuration that is between about 80 degrees C. and 150 degrees C., and in which the two more outer layers maintain their structural integrity to at least about 10 degrees C. greater than the first layer transition temperature.
