CoSn(OH)_6 nanocubes were synthesized by a facile one-step co-precipitate method. 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.
