Abstract

The invention discloses a ferrocenyl triblock copolymer and application thereof, and a ferrocenyl pseudocapacitor. The ferrocenyl pseudocapacitor comprises a working electrode, a reference electrode, a counter electrode and electrolyte, wherein the electrode manufactured by PFC28-PEO-PFC28 is the working electrode. The novel ferrocenyl triblock copolymer with controllable hydrophilic-hydrophobic property and a novel structure serves as a positive electrode material of a supercapacitor, and a novel ferrocenyl pseudocapacitor is developed by utilizing extremely excellent redox characteristic and film-forming property of the triblock copolymer. Through electrochemical characterization of cyclic voltammetry, constant current charging-discharging and the like, the PFC28-PEO-PFC28 is a good positive electrode material of the pseudocapacitor. The research result provides beneficial reference for developing the novel electrode material of the pseudocapacitor.

Description

technical field [0001] The invention relates to the technical field of supercapacitors, in particular to a ferrocene-based triblock copolymer and its application and a ferrocene-based pseudocapacitor. Background technique [0002] Supercapacitors have attracted widespread attention in recent years because of their high energy density, large specific capacitance, and high cycle life. In general, supercapacitors are divided into electric double layer capacitors and pseudocapacitors. Compared with electric double layer capacitors, pseudocapacitors are more attractive due to their higher specific capacitance and energy density due to the presence of Faradaic reactions. MnO 2 It is one of the most common pseudocapacitor electrode materials because of its very high specific capacitance (>1370F / g), environmental friendliness, and low cost. But MnO 2 The low conductivity (10 -5 -10 -6 S cm -1 ), making its magnification not high. In order to further improve the performanc...
