Cobalt-based perovskites exhibit fascinating physical properties at the nanoscale, being excellent candidates for applications in renewable energy storage devices. In this work, a technological approach using porous anodic aluminum oxide (AAO) as a template for the synthesis of low dimensional SrCo0.95V0.05O3 cubic perovskite, is introduced. Composite electrodes based on nanostructured perovskites and graphite show an improvement in electrochemical performance. Cyclic voltammetry as well as galvanostatic charge/discharge cycles experiments show a remarkable enhancementin the charge storage capabilities of the material due to the nanostructuration [1]. These results allow considering SrCo0.95V0.05O3 / Al2O3 / C composites as potential candidates to be used as electrodes materials on supercapacitor devices.[1] M. A. Salguero Salas, J. M.
