T
he storage and production of electrical energy is a major issue of the 21
st
century. Many methods are developed today for
embedded systems in the range of small storage. In this context, the development of nanoscale 3D structures makes it
possible to considerably increase the specific area of the material. By working on this surface increase but also on its reactivity
we can considerably increase the performances of the devices. We have developed in our laboratory electrochemical methods
for the production of ultra-dense align nanowires and nanotubes embedded in nanoporous alumina membrane with various
materials like metals (Cu, Au, Ni, Pt), semiconductors (Si, Ge) or dielectrics (TiO
2
, polymers) for their integration into electrical
devices in partnership with companies in link with industrial issue. We will present some of our results in various fields
of electricity production such as PtCu and/or PtNi nanotubes fuel cells, Si nanowires solar cell and thermoelectric devices.
We will also present their applications for electrical storage: 3D metal-insulator-metal capacitors, electrolytic capacitors, and
supercapacitors. Electrochemical elaboration as well as electrochemical operation will be presented.
