Au nanoparticles on N-doped carbon modified carbon cloth for flexible sodium metal batteries
摘要
A novel flexible sodium metal anodes were designed and fabricated via composite gold nanoparticles with N-doped carbon nanorods on carbon cloths. As-prepared anodes exhibit low overpotential and stable sodium plating/stripping over 800 h with superior reversibility at 5.0 mA cm−2. The flexible full batteries with NaVPO4F cathode are further assembled. The flexible batteries can deliver good cycle stability even under various bending angels and display excellent rate ability.
