We have synthesized and characterized hybrid nanomaterials capable of enhancing the specific capacitance of thin film supercapacitors.  Integration of supercapacitors into the renewable energy grid is critical for efficient use of periodic and transient sources such as solar, wind, and tide.  We use combinations of single walled and multiwalled carbon nanotubes as the matrix.  The nanotubes are functionalized by novel ruthenium coordination complexes at very low atomic percent.  At only a 0.3% Ru complex functionalization the specific capacitance of our thin films increased by 250%.  We will also present our results from our nantoube � NiO nanoplate composite films.  All of the materials are characterized spectroscopically, electrochemically, and structurally by SEM, TEM, and DLS.  Computation studies on these hybrid nanomaterials will also be presented.
