Their supercapacitor performances were investigated via a traditional threeelectrode system and all solid-state flexible asymmetric supercapacitor. The electrode shows a maximum specific capacitance up to 695 F·g^-1. The flexible all solid-state asymmetric supercapacitor was fabricated based on CoSn(OH)6 nanocubes and active carbon as positive and negative electrode. The assembled asymmetric supercapacitor exhibits a specific capacitance(97.3 mF·cm^-2), good rate/mechanical stability and a long cycling stability(5000 cycles), demonstrating great promise for applications in all solid-state flexible supercapacitors.展开更多
