Abstract
Los condensadores electroquímicos de doble capa (EDLC), comunmente denominados supercondensadores, son dispositivos de almacenamiento electroquímico de energía capaces de proporcionar más energía que un condensador común y cargarse o descargarse más rápido que una batería. Hoy en día, este tipo de dispositivos ha atraído un gran interés debido a tener una excelente reversibilidad, una capacidad de ciclado prácticamente ilimitada (>1,000,000 ciclos) y un modo de operación sencillo,ofreciendo soluciones en aplicaciones donde se requiere un aporte instantáneo de energía. Los esfuerzos e investigaciones actuales tienen como objetivo aumentar su densidad de energía sin perder potencia, para obtener nuevos dispositivos que alcancen o incluso superen la densidad de energía de una batería manteniendo las ventajas propias de los supercondensadores...
Electrochemical double layer capacitors (EDLC), commonly referred as supercapacitors, are electrochemical energy storage devices that can provide more energy than a common capacitor and deliver or capture it faster than a battery. Nowadays, this type of devices have attracted considerable interest because they have excellent reversibility, practically unlimited cyclability (> 1,000,000 cycles) and a simple operation mode, offering solutions in applications where a rapid energy boost is required. Current efforts and research are aimed at increasing their energy density without losing power, in order to obtain new devices that reach or even surpass the energy density of a battery while simultaneously maintaining the advantages of supercapacitors...
