主　　题：One step Cobalt tin hydroxides All solid Flexible Asymmetric supercapacitor 

摘      要：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.
