IMDEA Materials has a proprietary method to produce continuous sheets of nanostructured Silicon  (see Fig. 1) and their integration as high capacity anodes in Lithium-ion batteries without use of processing solvents or polymers. The electrodes combine high capacity (> 6 mAh/cm2), high Coulombic efficiency (> 99 %) and high capacity retention.
This technology spans from the synthesis of nanostructured sheets to the integration as fully-transformed electrodes in electrochemical devices. A semi-industrial process is used for the fabrication of continuous sheets of nanostructured silicon, compatible with different current collectors, supports or other downstream modifications. This material can be integrated in full cells of standard sizes (coin, pouch, etc), as well as in complex shapes, including designs with high curvature.
In addition to the fabrication of electrodes, IMDEA Materials has ample expertise in advanced characterization of nanostructured electrodes, including using in-situ spectroscopic and X-Ray diffraction techniques during electrochemical processes  and mechanical deformations .
