Carbon materials for an efficient use of energy by electrochemical devices

Abstract

[ES] El uso eficiente de la energía, en particular de la energía eléctrica, requiere de dispositivos que permitan su almacenamiento y posterior conversión en trabajo con alto rendimiento. Los dispositivos electroquímicos son especialmente eficientes ya que la ausencia de elementos mecánicos móviles permite conversiones con una eficiencia muy elevada. El rendimiento global del dispositivo depende de las prestaciones de los electrodos, las cuales dependen de las propiedades de los materiales que los componen. La mayor parte de los electrodos están elaborados con materiales de carbono, por lo que este campo de investigación ha experimentado un enorme crecimiento en los últimos años, en particular los relacionados con Pilas de Combustible Poliméricas, Baterías de ión litio, y Supercondensadores. En este artículo, se presentan las últimas tendencias en investigación en estos dispositivos tomando como referencia los artículos presentados en la pasada Conferencia Carbon 2012 celebrada en Cracovia.

[EN] The efficient use of energy, in particular electricity, requires devices allowing its storage and subsequent conversion into work with a high yield. Electrochemical devices are very effective since the absence of mechanical moving parts reduces irreversibility and provides high efficient conversions. The efficiency of the device depends on the performance of the electrodes, which depends on the properties of the materials that compose them. Because most of the electrodes are made from carbons, this field of research has experienced a tremendous growth in recent years, in particular for three devices: Proton Exchange Membrane Fuel Cells, Lithium Ion Batteries and Supercapacitors. This article presents the latest research trends in this field taking as a reference the papers presented at the Carbon 2012 Conference recently held in Krakow.
