Abstract

A novel asymmetric hybrid capacitor using LiMn₂O₄ and manganese oxide (MnO₂)/carbon nanotube (CNT) nanocomposite as the positive and negative electrode materials, respectively, and 1 M LiClO₄ in propylene carbonate (PC) as the electrolyte has been developed. To the best of our knowledge, this is the first reported assembly of an asymmetric hybrid capacitor with metal oxides for both electrode materials, and, especially, with MnO₂ as the negative electrode material. The discharge profile of the asymmetric hybrid capacitor shows a typical capacitive behavior with a linear slope. The asymmetric hybrid capacitor was able to deliver a specific energy as high as 56 Wh/kg at a specific power of 300 W/kg, based on the total weight of LiMn₂O₄ and MnO₂/CNT nanocomposite in both electrodes. These results clearly demonstrated a superior performance of this new type of capacitor with a higher specific energy compared to other types of asymmetric hybrid capacitors.
