| 英文摘要 | we proved that ice crystallized from water molecules within as-synthesized graphene oxide (go) can be used as a spacer among individual go sheets to form an expanded go aerogel with a three-dimensional porous network structure. this designed specific structure can be retained during further processes to form graphene paper. due to the fact that the as-fabricated graphene paper contains carbon defects and space in its infrastructure, this creates more electroactive surfaces and interfaces to significantly increase the faradaic reaction efficiency. with the introduction of redox-electrolyte k3fe(cn)(6) into a koh electrolyte, we can obtain a 95-fold increase in the specific capacitance compared with the value obtained in the traditional koh electrolyte. the ice-crystallization formed graphene paper electrode showed high electro-activity because the specific porous structure can favor the fast transfer of electrolyte ions, such as fe(cn)(6)(3-) ions. the presented results prove that ice-crystallization formed go can serve as a chemically tunable platform for electrochemical energy storage applications. |
