Description
Technical Field
The invention particularly relates to a preparation method of a Prussian blue-based flexible symmetrical supercapacitor, and belongs to the field of energy storage.
Background
With the rapid increase of energy demand, the development of high performance energy storage devices has become an urgent requirement, and materials with high energy and high power density have become hot spots of interest for researchers. Energy storage materials have numerous applications in hybrid vehicle, portable electronic and wearable device design. The super capacitor has the performance of the combination of an electrolytic capacitor and a traditional battery. In the last few years, sodium ion super capacitors have attracted much attention, have extremely high energy density, ultra-long cycle life, relatively low cost, and have broad application prospects in large-scale electric energy storage systems.
Transition metal-based hydroxides/oxides, sulfides, phosphides, etc. are often compounded with conducting polymers to form composites and used as electrode materials because such composites have multiple oxidation states, large capacity electroactive centers and can thereby initiate redox faradaic reactions, characteristics that make such composites promising electrochemically active materials. The structure of Prussian Blue (PB) is iron hexacyanide (Fe)4[Fe(CN)6]3) Having a Face Centered Cubic (FCC) crystal structure, is considered to be the first example of a synthetic coordination compound or metal organic framework compound. Compared to PB, Prussian Blue Analog (PBA) has a similar crystal structure, with some or all of the iron positions being replaced by other transition metal ions. Such analogs are more widely used in electrolysis, supercapacitors and batteries. Various transition metals such as Mn, Fe, Co, Ni, Cu and Zn are often used to react with sodium ferrocyanide to produce new prussian blue analogues. Among them, the prussian blue analogue Co-HCF containing Co shows great electrochemical activation and high specific capacity. On the other hand, Graphene (GO) is widely used as a dopant for semiconductor materials due to its abundant active centers, stable structure and high conductivity. In recent years, the advantages of graphene and prussian blue analogues are gradually shown, and the requirement of rapid development of supercapacitors is met. Since the symmetrical supercapacitor has excellent rate performance and long-life cycle performance and is easier to assemble, the capacitor is wearableIn energy devices, the research on symmetric supercapacitors is receiving more and more attention.
