Among different nanos-tructured MnO 2 thin films, the mesoporous weirds composed thin film obtained at temperature of 453 K exhibits excellent physical and electrochemical features for supercapacitor application. The weirds composed MnO 2 thin film exhibits specific surface area of 109 m 2 g ?1 , high specific capacitance of 595 ¡£¡£¡£¡£¡£¡£¡£ . In addition to this, MnO2 weirds attain capacity retention of 87 % over 2000 CV cycles,representing better cycling stability. The enhanced electrochemical performance could be ascribed to direct growth of highly porous MnO 2 weirds on carbon cloth which provide more pathways for easy diffusion of electrolyte into the interior of electroactive material. The as-fabricated electrode with improved performance could be ascribed as a potential electrode material for energy storage devices.weirds ¾ÍÊÇÀïÃæµÄMnO2 weirds Ôõô·Òë |
